Biology and Control of Invasive Fishes: Lessons Across Species and Regions

Abstract: Invasive fishes are rapidly becoming a primary challenge to fisheries managers worldwide. There does not seem to be any watershed or ecosystem that is not seriously threatened. The taxonomic variety of fishes that are invasive, the damage they cause, and reasons for their invasiveness are also extraordinarily diverse. Yet, common lessons can be drawn from different species and situations about how to study and control these species. This symposium seeks to identify these lessons by examining species from across the world (ex. Sea lamprey, common carp, Asian carp, brown trout, smallmouth bass, etc.), locales (Great Lakes, Mississippi basin, Australia, Japan, etc.) and approaches to control (ex. toxins, behavioral barrier, predators, integrated control) in new and integrative manners. A broad range of integrative ideas and approaches are solicited. Sub-symposia on special issues such as Asian carp are possible.

Teaming up Atlantic and Pacific Salmonid Biologists to Enhance Recovery of Endangered Salmon in North America

Abstract: Salmon hold an iconic status along the Atlantic and Pacific coasts of North America. These fish historically provided critical ecosystem services and substantial economic benefits to these regions. Over harvest, fish passage barriers, habitat destruction, in combination with other factors have resulted in extirpation of approximately 30% of Pacific and over 90% of Atlantic salmon populations in the contiguous United States. Many of these remaining native populations of Atlantic salmon, steelhead, and Pacific salmon are protected under the U.S. Endangered Species Act. Significant population declines are also occurring on both coasts in southern Canada. This conservation crisis has resulted in extensive research on salmon to inform management decisions associated with recovery of these endangered populations.
There is a large and productive research effort in North America focused on conservation of endangered salmonid populations. Numerous partnerships are in place to facilitate collaborations among researchers within the Pacific and Atlantic salmon research communities. In contrast, opportunities for sharing information between these two communities are less structured and usually occur on a small scale.
We are organizing a symposium to bring together pairs of Pacific and Atlantic salmonid biologists to identify areas where collaboration between these research communities would be beneficial. Each member of the pair will give an oral presentation synthesizing major findings for a management or research topic from a Pacific or Atlantic salmon viewpoint. After the symposium is completed, each pair will co-author a manuscript to distill research from both viewpoints in an effort to identify new perspectives or techniques to enhance recovery of endangered salmon populations. Potential topics include: hatcheries, pelagic ecology, smoltification, fish passage, estuarine environments, ESA listing and recovery, dam removal, landlocked forms, reintroductions, genetics, freshwater ecology, life history variation, population dynamics, fisheries, contaminants, climate change, and aquaculture.

Understanding the Ecological and Social Constraints to Achieving Sustainable Fisheries Resource Policy and Management

Abstract: Fish are the ultimate integrators of ecosystem changes as their diversity and productivity reflect changes in the composition of the airshed, the structure and function of upland ecosystems, and ground and surface water quantity and quality. To achieve healthy and productive fisheries, the integrity of freshwater ecosystems, as well as their connectivity to the landscape and to humans must be assured to better mediate the impacts associated with the ever-changing environmental conditions.  The link between the quantity and quality of freshwater and sustainable fisheries makes it imperative for researchers and managers to compare stressors on these resources among the principally agriculturally dominated, upper-Midwest landscapes to adaptively manage our fisheries for the benefit of both the ecosystem and society.  Only through understanding the requirements and benefits of healthy fish, healthy habitats and healthy people will sustainability of fisheries and aquatic ecosystems be ensured and economic and social prosperity be enhanced. The overarching goal of this symposium will be to determine the factors that facilitate or hinder fisheries sustainability in the United States.   More specifically, this symposium will address some of the most important stressors to fish populations, including: 1) climate change impacts to aquatic ecosystems; 2) shifting land use; 3) recent invasions of Viral Hemorrhagic Septicemia (VHS) in the Great Lakes region; 4) ecosystems effects of invasive species; and 5) the impacts of governance systems and policies on aquatic resources.   Presentations and discussions will focus on how these stressors impact fish habitat, communities, and production dynamics and will foster partnerships for research and solution development for conserving and restoring sustainable and economically viable aquatic ecosystems and fishery resources.

The Role of Molecular Genetics in Fisheries Management in the Great Lakes Region

Abstract: In 1980, the Stock Concept International Symposium (STOCS) brought together scientists and managers from the United States, Canada, and Europe to synthesize the state of knowledge about the stock concept and examine its potential role in fisheries management and rehabilitation of fish stocks in the Great Lakes region.  Genetic methods were highlighted as having great potential to describe genetic variation and population structure in aquatic species.  Since STOCS molecular techniques have advanced significantly and continue to play a role in stock assessment in the Great Lakes region.  Researchers across the Great Lakes have contributed collected genetic data for numerous species in all lake basins that have contributed significantly to management and rehabilitation efforts.  As issues that may impact past rehabilitation efforts and pose entirely new challenges emerge, this is an excellent time to assess the role of population genetics in stock based management of Great Lakes aquatic ecosystems by reviewing past research, examining the use of molecular techniques to address current and emerging issues and to learn about novel approaches that might be used to address emerging (and continuing) challenges.  Therefore, we propose a symposium to review the role of population genetics in stock based management and rehabilitation of Great Lakes aquatic ecosystems and to identify and prioritize future issues in fisheries management and rehabilitation in the region that may be addressed using genetic methods.  This symposium will bring together AFS members who work in the Great Lakes region on issues concerning stock based management to share ideas and learn more about the use of molecular techniques as well as researchers and biologists who work in other regions.

Valuing Alternative Views in Fisheries Management

Abstract: As the human population increases the pressure on global aquatic resources to provide food and other products will become even greater than now experienced. Isolated areas, such as the Midwest, will not be immune from the increased demand for protein sources. Human diversity in the United States is and will grow as we are now seeing other cultures, religions and genders changing the face of our work and societal environments. How can we begin to broaden our incorporation of new values into fisheries management?  The topic for this session will address suggestions for increasing and broadening fisheries management success by blending and valuing a diverse set of voices, views and basic understanding of traditions and cultures now. The objective is to expose more fishery workers to the value of knowing historic cultural expressions as well as alternate and new views on natural resources that might influence success of working relationships and co-management arrangements and decisions in a growing global world. The value is not just for AFS members but for all of human society and our global natural resources. Increasing the awareness of the need and desirability of incorporating cultural backgrounds and in understanding other views into decision making can only enhance future management.

Effects of Anthropogenic Chemicals on Chemosensation and Behavior in Fish: Organismal, Ecological, and Regulatory Implications

Abstract: The effects of anthropogenic chemicals on chemosensation and behavior in fish are growing ecological and regulatory concerns in North America.  Although these effects have recently been highlighted in the press for populations of anadramous salmonids in the Pacific Northwest, concern is now being raised about potential effects on other salmonids, other fish species, and other members of aquatic ecosystems across North America.  We propose a ½-day symposium in which platform presenters will discuss research on chemosensory and behavioral impairment in fish exposed to chemicals, the associated organismal and ecological consequences, and the regulatory implications.  The objectives of the symposium are to provide the audience with a comprehensive view of major concerns about impairment of chemosensation and behaviors caused by a wide variety of chemicals, and to bring researchers from various arenas together to identify common ground and remaining uncertainties.  AFS members will benefit because the fisheries community is being asked to comment on the importance of this issue and, in some cases, take management actions.  Novices and active participants in this field will be educated by a combination of overview presentations and results of recent research.  We will solicit abstracts from representatives of academia, government, and business.

Advances in Telemetry in the Great Lakes and Beyond

Abstract: The use of telemetry to study the movements of fishes has exploded in the Great Lakes. Without question, remote monitoring of behavior via telemetry is a powerful tool for addressing important management issues. However, use of these technologies is also accompanied by unique challenges that come into play at every stage of a study, including: study design, equipment deployment and retrieval, animal tagging, data collection and management, and analysis and presentation. This symposium will draw on expertise from both within and outside the Great Lakes basin to share experiences in conducting telemetry studies. Invited and contributed papers highlighting novel applications of telemetry and those addressing the challenges that are unique to telemetry studies will be given priority for oral presentations. Poster presentations are also welcome.

Development of Sustainable Fisheries Resources Internationally: Useful Tools in Simulations, Modeling, and Planning.

Abstract: Garhwal Himalaya is a region in Northern part of India and lies in the state of Uttarakhand.  This region has vast fresh water resources.  Two major snow fed rivers – The Ganges and The Yamuna originate in this region and they have many tributaries in form of smaller rivers and streams.  Many (approximately 44 ) hydro-electric power projects have either been built, are under construction or are planned.  These hydro-electric power projects have had an impact on fresh water systems in the region.  Similar conditions, if not exactly same, exist in many countries across the globe. This symposium is an effort to invite experts in simulations, modeling and fisheries management to develop and present their model for need based sustainable development of fisheries internationally. The symposium will provide an opportunity for all AFS members who are experts to develop fisheries internationally. Several tools designed by AFS members can be valuable in this international effort.

Innovations in Thermal Research and Ecological Effects of Thermal Discharges

Abstract: Despite nearly 40 years of  thermal regulatory requirements under the Clean Water Act, a significant void remains among scientists, regulated industries, regulators, educators and opposing groups on how thermal discharges affect aquatic biota and habitat in receiving waters. This void is not a result of disinterest or lack of effort, but more likely due to ineffective communications among these groups in describing innovative approaches, target organisms and results of thermal research as they try to understand thermal impacts. This symposium will highlight innovations and promising approaches being applied and tested to better understand thermal impacts on organisms in receiving waters of freshwater and marine environments. Finally, the symposium will highlight strategies for better communicating thermal research among interested parties.

Fisheries Data Dissemination – Building Better Networks

Abstract: Fisheries professionals have always collected copious amounts of data, but we don’t always do all we can with those data.  Recently advances in technology have allowed improved collection and organization of data, and now many entities are also making profound changes in how they disseminate those data.  Researchers have the ability to access data collected over broad spatial and temporal scales, managers have increased ability to make data-based decisions, and anglers can now view and compare fish survey information on systems where they recreate.  Organizing a meeting of leaders in this field to present their work and discuss new advances will help everyone improve their respective systems.

Diel Vertical Migration: Scaling Down From Populations to Individuals

Abstract: Diel vertical migration (DVM) is a pervasive behavior in marine and freshwater food webs and affects processes ranging from individual physiology to ecosystem function. Many pelagic organisms, ranging from the smallest autotrophs to the largest predators, undergo DVM to survive, grow and reproduce in vertically heterogeneous pelagic environments. Despite the common treatment of DVM as a population-level process, there is evidence to suggest that the timing and frequency of vertical movements of individual organisms may be highly variable within overall population migrations. Such asynchronous behavior could result in continuous and multiple vertical interchanges across habitat boundaries, which could have multiplicative effects on estimates and inferences of ecological processes across boundary layers when compared to a single vertical interchange often assumed under the population-level view of DVM. This session will extend beyond the population-level perspective of DVM and explore DVM at an individual level for organisms ranging from autotrophs to apex predators. We invite contributions that present new methodologies for assessing and quantifying DVM by individuals, empirical and modeling studies that address the causes and consequences of individual variation in DVM, and syntheses that evaluate the impact of individual variability in DVM on population-, community-, and ecosystem-level processes. This symposium will bring together researchers and managers from freshwater and marine systems working across multiple trophic levels, and thus supports the meeting’s theme of building fisheries networks across ecological and geographic boundaries.

Comparing and Contrasting Fisheries Research and Management Paradigms Across Marine and Freshwater Ecosystems

Abstract: Fisheries science and management face common challenges in both freshwater and marine systems due to overfishing, habitat loss, and food web changes brought about by invasive species. Despite recent declines in fisheries resources, there have been management successes in both marine and freshwater fisheries. This symposium provides a forum for scientists to discuss and share research and management tools through case studies of how various fisheries concepts and paradigms were applied to achieve management goals. Examples of research topics that cross marine and freshwater systems include: estuarine studies, invasive species control, fish early life history paradigms such as match mismatch and critical stage hypothesis, stock assessment, harvest policies, and fisheries management governance structures.

Calibration, Validation and Other Recent Progress on the AFS Standard Methods for Sampling Freshwater Fish.

Abstract: In 2009 the American Fisheries Society published Standard Methods for Sampling North American Freshwater Fishes, which was developed through a collaboration of 284 biologists from 107 state, provincial, federal, local and private agencies and organizations across Canada, Mexico and the United States.  This work provides AFS standard recommendations for sampling freshwater fishes, thus improving the ability for North American fisheries scientists to communicate and compare data across agencies, regions or time ranges on a continental scale. Since the publication of the book, much additional work has been conducted on AFS standard methods.  Scientists from various states, provinces and nations will discuss recent progress on validating and calibrating the standard techniques; developing web-based programs for comparing standard data; opportunities for data sharing worldwide; incorporating updates in techniques, and adoption of standard techniques. This symposium will allow an interchange among North American fisheries scientists to provide direction for future incorporation and development of standard techniques. A symposium on the AFS North American standard sampling program is directly related to the theme of the Twin Cities AFS conference: Fisheries Networks: Building Ecological, Social, and Professional Relationships.

The Interdependence of Fish Populations and Their Food Webs in Temporally Varying Environments.

Abstract: A defining characteristic of the limnetic ecosystems of North America is the presence of strong short and long-term variation in the relationships linking fish populations to their supporting food webs.  Recent climate change has imposed a consistent temporal trend on this variation which is becoming increasingly evident in the time series from many systems spread across the continent.  This symposium focuses on studies that illustrate how differences in climate, and other environmental factors, shape these population-food web relationships.  Study systems range from walleye and lake trout populations in lakes distributed across North America to cyprinid populations in the Everglades. A symposium on environmentally driven shifts in the relationships linking fish populations to their supporting food webs is directly related to the ecological aspects of the theme of the Twin Cities AFS conference: Fisheries Networks: Building Ecological, Social, and Professional Relationships.

Free Data: Opportunities in Open-Access Network Databases to Advance Spatiotemporal Scales of Inquiry in Fisheries Science

Abstract: Novel NSF-funded, grassroots, and agency initiatives are poised to provide high-quality, open-access data distributed across broad spatial and temporal scales with direct or indirect ties to fisheries science. Such resources will allow researchers to conduct unprecedented analyses well beyond what may be achieved using the facilities of individual laboratories. Yet the full potential of such initiatives will only be realized if the scientific community is cognizant of the available data. Symposium presentations will introduce programs such as the National Ecological Observatory Network, the Global Lakes Observatory Initiative, the National Fish Habitat Action Plan, and the National Ecological Data Base (National Water Census) as well as regional or local initiatives that offer open-access data to researchers. Presenters may also discuss findings derived from such initiatives that serve as examples of how these systems may benefit individual fisheries scientists. To help foster interdisciplinary collaboration among AFS members, presentations will include marine, estuarine and freshwater system-targeted programs as well as those with indirect ties to fisheries science, such as hydrological or atmospheric databases. Central to the discussion will be linking appropriate hierarchical scales, such as river networks, watersheds, and coastal environments and comparing these datasets to spatially contiguous layers of information to address questions of interest.  Presentations may also involve the utility of various raw (e.g. presence/absence) or synthesized (e.g., areas of potential vulnerability) datasets in aiding management decisions and promoting future research.  Consequently, AFS members attending this symposium will become familiarized with open-access data resources that they may not be familiar with, learn how to access such data, and receive introductions to initiatives that may foster interdisciplinary collaboration.

Making Native Fish and Their Habitat Relevant: Contemporary Challenges and Creative Solutions to Generate Broad Public Interest

Abstract: Human connections to fish and the waterbodies they inhabit are evolving, and, in many cases, atrophying. To the majority of U.S. residents, fish go largely unseen in their natural habitats. When they are seen, it is often as highly processed food items of unfamiliar or unstated origin. Anglers that directly interact with fish when they are in their natural habitat are a minority, and angler recruitment and retention is declining nationally.  According to recent studies, approximately 40% of fish taxa in North America are imperiled.  For the majority, habitat degradation from human activities is the primary cause of imperilment. General public apathy towards fish and their habitat needs suggests our communication strategies need to better reflect an understanding of contemporary behavioral motivators and what factors are constraining meaningful public interactions with fisheries and participation in fish habitat conservation. Effective public outreach is increasingly a critical component of any successful fisheries or fish habitat conservation program. The objective of this symposium is to introduce contemporary challenges/constraints, and highlight creative ways to increase the relevancy and visibility of fish and their habitat needs to a broader segment of society.

Stakeholder Involvement in Fisheries Science: New Approaches and New Partnerships

Abstract: Stakeholder involvement in fisheries issues is increasing and cuts across traditional boundaries between scientists and citizens. These partnerships now support novel outreach programs, stakeholder involvement in management decisions, and even citizen scientists collecting research or monitoring data. This approach is being revolutionized by changes in electronic communication. This symposium will illustrate what can be achieved by showcasing outcomes from a broad range of partnerships, with emphasis on identifying attributes and processes that made them successful.

Wildlife and Sport Fish Restoration 75th Anniversary

Abstract: The year 2012 marks the Wildlife and Sport Fish Restoration 75th anniversary.  Both Pittman-Robertson Wildlife Restoration and Dingell-Johnson Sport Fish Restoration (SFR) support unique user-pay, user-benefit partnerships among industry, federal and state fish and wildlife agencies, sportsmen and sportswomen, and conservation organizations.  SFR has been a major financial contributor since 1950 for stable and secure funding to improve sport fish populations and aquatic habitats while also providing recreational opportunities.  A total of $7.3 billion from excise taxes on fishing equipment and motorboat fuels has been matched with at least $2.4 billion primarily from state fishing license sales over that time period.  This symposium will provide historical, current and future perspectives on the SFR program from leaders of national and state partner organizations.  Introductory presentations will cover the history of the SFR Act, its funding and mechanics, and its contribution to enhancing professionalism in the field of fisheries science.  The main body of the symposium will feature the wide variety of projects supported by SFR, primarily through projects and case studies from state resource agencies recognized in recent years by the AFS Fisheries Administration Section through their Outstanding SFR Project Awards program.  These include habitat acquisition or improvement, fishing access development, research and surveys, and aquatic resource education.  Project locations range from headwater stream to ocean habitats.  Other presenters will describe key national programs supported by SFR and provide sport fishing industry perspectives, including return-on-investment of excise taxes supporting the SFR program.  The symposium will conclude with visionary comments on political support, funding outlook, and the continuing need for highlighting SFR program accomplishments.

Fishery Information Networks As Agents of Change

Abstract: A key to effective fisheries management is good communication within the management community. New technologies now allow communication at a speed and depth of information not possible even a few years ago.  These technologies are being applied to vessel monitoring systems and fishery information networks worldwide.  New systems are usually designed to meet a narrowly defined need, with little consideration for broader possibilities within individual fisheries or among fisheries and fishery sectors. Tighter information linkages among fishermen, scientists, managers, marketers, and the public can lead to new collaborations within the fishery community.  This opens up opportunities to improve fishery science, rationalize harvest while conserving stocks, and create new marketing strategies.  At the same time, fishermen may take a more active role in data collection and analysis, leading to changes in the social structure of the management community. In our view, this change is necessary to the future of fisheries.
In this symposium we will explore a new range of possibilities for fishery management and science, identifying opportunities based on modern communication and data collection technologies. We will explore the nature and direction of desirable change and identify incentives for and impediments to change.  The hope is to foster the use of new information technologies to improve the enterprise of fishing in the broadest sense. Potential topics include: Visions for future management scenarios; Technology – state of the art and coming developments; Economic opportunities; Social implications; Change agents and engines; Case studies.

Effects of Climate and Land Use Changes on Fish and Fish Habitat in Streams and Lakes: Special Emphasis on Strategies for Fisheries Management and Conservation

Abstract: Freshwater ecosystems are increasingly challenged by threats including climate and land use changes.  Planning for and implementing strategies to cope with changes to freshwater ecosystems can be difficult for resource managers.  These changes are likely to affect aquatic systems by altering flow, temperature, and sediment regimes as well as concentrations of nutrients and toxins.  Habitats (reach/network scale) are not equally vulnerable to changing environmental conditions, and fish perceive these effects differently.  Effects of climate change on water temperature and flow regimes are expected to alter freshwater habitats in lakes and streams and lead to changes in fish abundance and distribution, with declines predicted for many temperature specialists, often native species.  Conversion of catchment land area to urban and agricultural uses has been directly linked with disruptions in stream integrity and loss of fish diversity across the United States.  In combination, changing climate and land use patterns pose particularly serious threats to aquatic systems.  This symposium will examine the potential effects of climate and land use change across multiple spatial scales in the conterminous United States. We invite contributions that: 1) demonstrate the transformation of aquatic habitats due to historical changes of climate and land use, or 2) incorporate downscaled Atmosphere-Ocean General Circulation Models and projected land use models to identify how future climate and land use will affect fish distributions, fish behavior (spawning, foraging, interactions, etc.), and fish habitat in lakes and streams at various spatial scales.  Specifically, we will report on research based on approaches that can serve as a framework for future investigations to identify the large scale effects of changing patterns of climate and land use on fish and their habitats.  The results from this symposium will identify important habitats for conservation or restoration and especially potential management options for managing these changes in our aquatic landscape.

Connectivity in Coastal and Estuarine Ecosystems: Patterns, Processes and Consequences

Abstract: Agencies, at all levels, are seeking to develop ecosystem-approaches to management (EAM) of fisheries in efforts to ensure long-term sustainability of the exploited marine resources and ecosystems.  In the marine realm, ecosystem approaches are challenged by the open nature of ecosystems.  The openness of these ecosystem results from two important mechanisms:  the direct exchange of fish, invertebrates and mammals among ecosystems and the spatial segregation of recruitment and spawning in many species.  These two processes produce a complex pattern of connections among coastal and estuarine ecosystems that has important consequences for the resilience and sustainability of networks of coastal ecosystems.  The resultant connectivity among marine ecosystems highlights the importance of selecting the appropriate spatial scale for scientific investigations and management.  This symposium highlights recent research that seeks to quantify the pattern, levels and consequences of connections among coastal and estuarine ecosystems.  Presentations will discuss connectivity issues in the Atlantic, Pacific and Caribbean basins.  The symposium will highlight statistical methods that quantify the pattern and level of connectivity, empirical approaches that measure rates of exchange among ecosystems together with modeling techniques that explore the consequences of differing levels of connectivity to ecosystem resilience and sustainable management.  To conclude the symposium, we will seek to synthesize across different systems to understand broad principles of the implications of connectivity for management of coastal and estuarine ecosystems.

Fish Habitat Condition Assessment in the Midwest and Great Plains

Abstract: Since 2006, state federal and tribal governments and their conservation partners have been working together across the Midwest and Great Plains to develop Fish Habitat Partnerships (FHP) under the National Fish Habitat Partnership (formerly known as the National Fish Habitat Action Plan).  Six FHPs have grown with independent missions to address a common problem, habitat degradation.  As the FHPs formed they quickly realized a shared need to understand the scope and severity of aquatic habitat degradation across the landscape.  In 2009 they jointly undertook the three year task of assessing aquatic habitat condition by modeling cumulative impacts of primarily terrestrially based anthropogenic stressors in stream and lake catchments.  This symposium will address the science behind the models, mapping products, and decision support tools being made available to fishery management organizations and others interested in aquatic conservation.  Symposium speakers will discuss the data, analysis, and results of thirty-two independent fish habitat condition modeling efforts, the challenges of such an effort, the advantages of working together, and importance of this information in making strategic fish conservation decisions at the landscape and local scales.  This foundational effort paves the way for much more investigation into the causal relationships between independent and cumulative human disturbances within watersheds and the subsequent impact to aquatic habitat and fisheries.

Standardization in Hydroacoustic Assessments: Fundament or Folly?

Abstract: Hydroacoustic sampling is a common and useful tool for the assessment of aquatic and marine organisms.  Technological and theoretical improvements are consistently occurring, but comparability of data from different environments is often limited (or perceived to be limited) by differences in equipment, sampling, and data analysis techniques.  While some effort has been made to identify factors that impart incomparability and to develop/adopt standards to minimize differences, uncertainties remain.  We propose a symposium to review and synthesize the need for and importance of standardization in hydroacoustic assessment.  Our primary objective is to identify areas in which standardization efforts remain necessary and critical to improve comparability of research.  We invite presentations from aquatic and marine environments that compare and contrast multiple methods of assessing organisms and communities using hydroacoustics.  Examples of topics include comparisons of frequencies, equipment, software, deployment techniques, and density apportionment to species or size groups.

Understanding Complex Linkages Between Fish and Fisheries in a Changing Ocean

Abstract: Fisheries scientists have long recognized that fish abundance is strongly influenced by conditions in the natural environment, and for exploited populations, by the direct influence of humans through fishing.  Environmental conditions encompass both the physical environment as well as ecological properties including the abundance of predators and prey.  Predator-prey relationships create dynamical linkages between fish populations.  Fishing which is influenced by environmental conditions as well as economics and regulations introduces another set of complex dynamics that can link seemingly separate fisheries.  Understanding how changes in one exploited population propagate to other components of the ecosystem is a key requirement for fisheries management to move towards an ecosystem approach.  This symposium aims to explore how linkages among fish populations and between fisheries ecosystems and socio-economic systems influence the dynamics of fish populations around the world.

Upper Mississippi River Restoration: Combining Habitat Rehabilitation, Monitoring, and Research to Enhance Fish Communities.

Abstract: Congress authorized the Upper Mississippi River Restoration – Environmental Management Program (UMRR-EMP) in 1986 to help address ecological needs on the Upper Mississippi River System.  The U.S. Army Corps of Engineers administers the program, which emphasizes habitat rehabilitation with long-term monitoring and research.  The habitat rehabilitation component includes techniques such as dredging backwater areas and channels, constructing dikes, creating and stabilizing islands, modifying flow into channels and backwaters, and controlling water levels to address habitat needs.  The long-term monitoring component addresses status and trends of selected resources, conducts research on river processes and functions, develops products to help make resource management decisions, and maintains river information databases.  The Program is implemented through a partnership including the U.S. Army Corps of Engineers; U.S. Fish and Wildlife Service; U.S. Geological Survey; U.S. Environmental Protection Agency; U.S. Department of Agriculture; the states of Illinois, Iowa, Minnesota, Missouri, and Wisconsin; and various non-governmental organizations, business interests, and private citizens. 
UMRR-EMP was the first program in the nation to combine ecosystem restoration with scientific monitoring and research efforts on a large river system.  The Program has completed 54 habitat projects benefitting approximately 100,000 acres of aquatic and floodplain habitat and contributed significantly to our scientific understanding of this complex system through monitoring and research.  UMRR-EMP has served as a model for other river restoration and monitoring programs, both nationally and internationally. 
The objective of this symposium is to address two main questions:  (1) what have we learned, and (2) how have we affected the system?  Presentations will address program history and organization, development of desired future conditions, insights gained from monitoring, restoration designs and planning tools, ecological and social benefits realized, case studies of rehabilitation projects, and application of adaptive management.

Moving Beyond Distribution and Abundance in Quantifying Fish Habitat Selection

Abstract: Identification of species’ distribution and abundance in response to environmental variability and ecosystem dynamics is the basis of much first-level work in fish ecology.  The important correlates of species distributions and abundance are informative metrics for evaluating the potential of a species to persist in a particular habitat type and what restrictions exist on the species’ productivity, density, or abundance. Although these studies certainly have value, conclusions are often difficult because seemingly appropriate habitat appears under-matched by fish density. This is likely because important ecological and processes that are critical for understanding mechanisms of fish species resilience have been overlooked.  In fact, numerical density can be misleading in situations where smaller sub-populations actually have higher survivorship, fecundity or other response correlated with fitness. Behavioral and life history responses to predation risk, competition, parasites or pathogens often incorporate important selective processes that can vary significantly over a species range.  Theoretical approaches may also provide a conceptual basis to guide empirical studies that expand the understanding of mechanisms that enable species persistence in specific habitats or ecosystems.  In this symposium, we invite speakers working on a range of species responses to spatial heterogeneity in habitat conditions in aquatic, and marine environments, who have found unique insights into the ecology of the species by examining responses beyond distribution and abundance, including life history, individual condition, behavior, and plasticity in response.  We also invite speakers working on novel theoretical approaches that consider processes that affect the fitness and/or persistence of populations across the range of variation in habitat types.

Lake Trout East and West: What Can We Learn by Comparing Lake Trout Restoration in the Eastern USA to Lake Trout Suppression in the Western USA?

Abstract: We propose to address the question, what can be learned by comparing lake trout restoration in the eastern USA to lake trout suppression in the western USA?  In the Laurentian Great Lakes, lake trout were historically dominant, but underwent catastrophic declines caused by over-fishing, non-native species invasions, and habitat degradation.  Lake trout management in Laurentian Great Lakes now focuses on restoration or rehabilitation of the species.  In contrast, lake trout were introduced into many western lakes and are now overwhelming fish assemblages in many of those lakes, with devastating effects on native species, such as bull trout, rainbow trout, and cutthroat trout.  In many western lakes, fishery management now focuses on lake trout suppression to restore native depleted species.  Our symposium proposes to borrow information learned for one purpose, such as how to restore a depleted species, for the opposite purpose, such as how to suppress an invasive species.  The lake trout provides an excellent example of a species that is managed for opposite goals (restoration versus suppression) that depends on its historic role (native or non-native) in aquatic communities.  The symposium will provide AFS members and participants with an opportunity to study the use of common biological information about a species to develop diametrically opposite management goals.  The symposium will be organized around case examples to be presented by leading experts on lake trout restoration in the Laurentian Great Lakes (Superior, Huron, Michigan, Erie, and Ontario) and lake trout suppression in western lakes (e.g. Yellowstone, Flathead, Pend Oreille, and Glacier NP).

Role of Forage Species in Ecosystem Approaches to Management

Abstract: Forage fish are a particular category of fishes bound together more by the ecological role than by their taxonomy or habitat occupancy.  They are small, abundant, schooling fishes (e.g., menhaden, anchovy, herring) that constitute a large fraction of diets in marine predators such as groundfish, striped bass, marine mammals, seabirds, etc. Extensive fisheries have developed on both the East and West coasts of North America (as well as internationally) for forage fish, and constitute a large percentage of the national landings.  This has generated concern not only for the forage species involved, but for all higher trophic level organisms that consume them. Fundamental for Ecosystem Approaches to Fisheries Management is the need for population data, trends and models focused on forage species and their multiple species interactions and stressors, but this information is uncertain in many instances.  The ultimate goal of the symposium is to review and discuss recent advancements in research, conservation, and management efforts towards forage fish which will enable AFS members to quantify the links between forage fish and other components of the ecosystem (from plankton to top predators and humans).  By AFS members exchanging information on how to describe and model the ecosystem-based consequences of different management options, the symposium will advance the knowledge needed to address which tools exist or need to be developed for management to assess economic and ecological changes in a meaningful manner.

New Perspectives in Fish Habitat: Remote Sensing, Modeling, and Scaling

Abstract: Quantification of aquatic habitat is an essential aspect of understanding the response of fish populations to a large spectrum of human perturbation. However, traditional on-the-ground methodologies have suffered from being site- and time-specific, and thus not readily conducive to extrapolation. A proliferation of newly evolving techniques is now allowing for the evaluation of fish habitat at a variety of spatial and temporal levels. In this symposium we explore some recent developments in remote sensing and spatial modeling that will allow us to view fish habitat at a variety of scales. These methods will assist greatly in our ability to manage fish populations in the face of inter-related fisheries pressures, habitat fragmentation and degradation, and climate change.

Great Lakes Fish Communities: Tales, Lessons, and Futures

Abstract: Each of the five Great Lakes shares common histories of exploitation and environmental degradation, though to varying degrees.  Throughout the 20th century, fish communities of all of the Great Lakes underwent massive changes and change continues to be a hallmark of these communities in the 21st century.  In the lakes Michigan, Huron, Erie, and Ontario, many native species have been lost and replaced largely with invasive and introduced exotics; only Lake Superior retains a relatively natural assemblage.  Moreover, the invasion and expansion of dreissenid mussels in the lower lakes has drastically altered their ecosystems by shunting energy and nutrients into a benthic sink and caused trophic cascades in some lakes like Huron.  In order to better understand similarities and differences among the lakes, researchers in the past decade have been comparing trends in abundance of prey species, trophic structure and organization, and energy transfers and linkages. The goal of these studies is to assess the potential for restoration of native fishes in the lower lakes (especially with the decline of alewives in lakes Michigan and Huron) and to restore a level of ecosystem stability comparable to that in Lake Superior.  We invite contributions that compare physical environments of the Great Lakes and their biological communities.  We would like to present a range of papers that describe differences and trends in lower trophic levels (microbial, nanoplankton, plankton) to upper trophic levels (prey and predator fishes) and use of models to compare and contrast ecosystem structure and organization.  Finally, we invite papers that address the potential for restoration of native fish communities in the Great Lakes.

Fish Habitat and the American Reinvestment and Recovery Act of 2009

Abstract: The American Reinvestment and Recovery Act of 2009 didn’t just fund road infrastructure improvements, it also supported work to improve fish habitat across the country.  Millions of dollars went toward a diverse portfolio of projects such as dam removals, culvert replacements, and efforts to remove marine debris.  The objective of this half-day symposium is to report on the progress of these projects, describe the successes and frustrations associated with managing this funding, and ponder the long-term effects.  Presenters will relate their experiences with managing high-value, high-visibility projects on a short timeline.  Agencies represented in the presentations will likely include NOAA, USDA, and the U.S. Army Corps of Engineers.  This symposium should be of interest to AFS members and participants who work in the fields of habitat restoration, estuarine science, and bioengineering.

Double-Crested Cormorants and Fisheries Management: Policy, Perceptions, and Research

Abstract: Continued recovery of continental double-crested cormorant populations have lead to increased social conflict and the pursuit of remediation at local and broader scales.  Consequently, the subject provides a unique overlap between wildlife and fisheries disciplines and carries the potential for competing approaches when managing exclusively.  Concurrent research describing cormorant diets and their interactions with fisheries is expanding and management policy is under review.  The objective of this symposium is to provide agencies context when seeking a multi-discipline approach for the sustainable management of both avian and fisheries resources.  This symposium seeks to blend the technical aspects of cormorant-fisheries research with the social and policy components to provide all levels of professionals a better understanding of cormorant interactions with aquatic resources and their users, future research needs, and management policy. While this symposium will focus on double-crested cormorant-fish interactions, presentations on other piscivorous birds, such as white pelicans, and their influence on fisheries resources are also welcome.

The National Fish Habitat Partnership – Building Relationships to Enhance Conservation of Aquatic Ecosystems

Abstract: Fish Habitat Partnerships – the primary work units of the National Fish Habitat Action Plan – were conceived as a means to involve diverse groups of public and private partners; engage the grassroots in fish habitat conservation; collaboratively develop a compelling vision; leverage different sources of funding and support through local and regional partnerships; and collectively assimilate and interpret the best available science on key geographic areas and fish habitats.  Since 2006, a network of 18 Fish Habitat Partnerships has developed to include all 50 States, engaging thousands of partners in on-the-ground projects and scientific assessments that support strategic conservation of fish habitats.  Speakers in this symposium will present case studies showing how building relationships within and among the Partnerships has advanced science on multiple scales; leveraged available funding; and engaged crucial non-traditional partners, including businesses, landowners, and local communities for the benefit of aquatic habitats and sustainable fisheries.  Speakers will also explore the future potential of relationships to address unmet and emerging needs, such as quantifying socio-economic benefits of healthy fish habitats; developing financial mechanisms linked to ecosystem services; and fostering a broad understanding and support for healthy fish habitats as a component of healthy human communities.

The Future of Fishing: Leisure, Sport and Conservation

Abstract: Fish management in the United States is in a state of flux.  Management agencies are adept and efficient at raising and stocking sport fishes, and understanding factors that impact fish populations; yet, concurrent with our ability to provide fishing opportunities, we have witnessed a significant decrease in the proportion of the human population that fishes, coupled with changes in the preferences of anglers for different types of fishing opportunities.  At the same time, agencies spend increasing resources dealing with other types of activities, such as invasive species, athropogenic habitat modifications, and endangered species.  These trends raise concerns about the future of recreational fishing, and the ability of agencies to provide for the continued conservation and management of fish resources.  This symposium brings together researchers and fisheries managers interested in the so-called “human-dimensions” of recreational fishing, with a focus on fishing motivations, constraints, and anglers’ preferences for fish conservation and management.  We believe that reconnecting with and extending the theoretical traditions that have been developed to understand and better provide for recreational fishing opportunities are important steps to ensuring the future of fisheries and the connection of the public to recreational fisheries.

Science and Management Community Aquatic Habitat Connectivity Discussion

Abstract: It is recognized that, in general, dams and other anthropogenic barriers are detrimental to riverine ecosystems; they fragment habitat and may block seasonal migrations of Great Lakes fishes and other aquatic organisms which rely on tributaries for spawning or other components of their life history.  It is also recognized that there is increasing interest from governments (federal, provincial/state, municipal), non-government organizations and private individuals to decommission dams, particularly those at or beyond their anticipated life expectancy.  In the future, it is expected that agencies will be required to review an increasing number of proposals to remove or modify barriers, some of which are crucial in the control of sea lamprey, protection of threatened, endangered, and native species, and prevention of pathogen and contaminant spread. These proposals may originate either from within agencies, or through stakeholder interests.  A science and management community discussion of fish passage issues hosted by the American Fisheries Society, taken as a first step, will help frame the data and product needs to then drive development of a suite of fish passage principles, tools, protocols, and policies with the objective of voluntary implementation by agencies and jurisdictions first within the Great Lakes basin and then throughout North America.

Collaboration Through Fisheries Networks: Restoration of Sturgeon and Paddlefish Populations

Abstract: Description: At present all 9 species of sturgeon and one species of paddlefish found in the U.S. are in some degree of conservation jeopardy, with some facing a high risk of extinction.  As such, great effort and resources are devoted at the federal, state and or local levels to protect and recover these species.  Through our symposium, we will examine the application of sturgeon and paddlefish recovery actions utilized throughout North America, with the intent of identifying shared successes and failures.   This symposium will facilitate network development and information sharing among sturgeon and paddlefish researchers in North America, and will ultimately aid managers and researchers as they identify actions to recover these species. The relative uniqueness of sturgeons and paddlefish has led to the natural development of a fisheries network that others can use as a model when developing networks for other species.  AFS members will benefit from this symposium’s presentations and discussions, as lessons learned may be applied to other species faced with similar anthropogenic threats.

Missouri and Mississippi River Flooding 2011: Impacts of Historic Flows on Big River Systems

Abstract: The Missouri and Mississippi River ecosystems have been leveed and dammed to control flooding and facilitate the transportation of goods.  While generally successful in keeping floods at bay, these anthropogenic river training structures permanently altered the ecosystems of these two large rivers by disconnecting them from their associated floodplains.  During 2011, excessive spring runoff caused by snow melt and high rainfall events overwhelmed the capacity of these structures, creating calamitous floods.   Although catastrophic for the people and communities located along the rivers, the flood of 2011 provided scientists an opportunity to investigate the function of floods on large river biota.  Missouri and Mississippi river basin states employed varying strategies to monitor flood impacts on aquatics resources.  Specifically, scientists evaluated entrainment through the mainstream dams, immigration and emigration from floodplain habitats, destruction and creation of habitats, productivity and endangered species throughout the high flow period.  This symposium will serve as a venue for those scientists to describe the direct effects of the flood, and to set the foundation for determining the long term effect the floods of 2011 had on the Missouri and Mississippi Rivers’ ecosystems.

The NOAA Habitat Blueprint: Improving Fisheries, Marine Life, and Coastal Communities Through Habitat Conservation

Abstract: Healthy coastal and marine habitats generate over two million jobs and over $250 billion annually, but are being lost and degraded at a rapid rate. This day-long two part symposium will provide AFS participants with an overview of the NOAA Habitat Blueprint–a new initiative to address this challenge–and the opportunity to participate in initial scoping of a specific topic under the Blueprint.  
Part I will provide an overview of NOAA’s Blueprint, a new, forward-looking framework for NOAA to think and act strategically across programs and with partner organizations (including many AFS members) to more effectively protect and improve habitat conditions for fisheries, coastal and marine life, and coastal communities.  The Blueprint is comprised of four key approaches: implementing regional habitat initiatives; establishing geographic priorities; implementing a systematic and strategic approach to habitat science; and strengthening policy and legislation.  Presentations and panel discussions will focus on specific activities underway supporting these approaches, and will seek to build linkages for future collaboration and highlight opportunities for symposium attendees to engage in both regional and national-scale efforts under the Blueprint.
Part II of this symposium will allow AFS participants to participate in scoping approaches for more effectively applying existing habitat conservation authorities to achieve sustainable fishery outcomes.  Management approaches under the Magnuson Stevens Fishery Conservation and Management Act have largely focused on controlling fishing effort and mortality to achieve a stock objective.  This focus has been necessary and a major achievement for NOAA Fisheries and fishermen.  However some stocks may not respond well to these types of controls in part due to their dependence on healthy habitats.  Presentations will focus on: 1) impediments to applying existing habitat conservation authorities to achieve fisheries goals; 2) options for developing habitat conservation objectives for fisheries managers; and 3) gathering recommendations for implementing such objectives.

The New Food Web: Emerging Methods for Bringing Together Social and Ecological Networks

Abstract: Intact food webs underlie the sustainability of fisheries worldwide. Our approach to understanding food webs is undergoing a rapid expansion of ideas and approaches. These innovative approaches include new elemental and chemical biomarker techniques to identify poorly understood trophic connections, community based models to understand interactions among species, whole ecosystem models to understand ecosystem-level drivers of food web dynamics, and social network analytical methods to characterize and model interactions between humans and fisheries. Fundamentally, fisheries are humans harvesting animals from aquatic systems, and humans collaborate and compete to harvest fish – they share (or fail to share) information about the locations where fishing is best, innovate harvest methods, and have highly overlapping economic strategies. Fishing regulations impact the food web indirectly by impacting the human behavior. Humans are also responsible for the dispersal of invasive species (e.g, dreissenids, lionfish). These human behavioral interactions can be modeled as well as the ecosystem species interactions using coupled ecological social network models.  These modeling efforts have the potential to reveal how changes in any one part of these coupled systems can impact seemingly unrelated elements of the overall system, as, for example, in both the direct and indirect effects of fisheries regulations on not only human behavior but also food web and supply chain dynamics.  We invite contributions to this session that presents new methodologies for characterizing, assessing, and quantifying aquatic food web networks across a range of ecosystem types and spatial and temporal scales. We anticipate that these food web approaches are being applied to address emerging problems that affect food web functionality, such as new fishing methods and innovations, regulatory impacts, marine protected areas, climate change, cultural eutrophication, invasive species, and over-fishing. This symposium will bring together social and natural scientists using a common analysis and modeling technique – network analysis.

Making the Connection Between Land, Water, and Sustainable Fisheries: Management Beyond the Aquatic Zone

Abstract: Good water quality, which is highly dependent on land use practices, is imperative to strong fisheries. Land based planning and activities in many cases are largely detached from their direct implications on water quality which pose significant challenges to sustainably managing commercial, recreational and ecologically important species. These issues are evident in freshwater and saltwater systems alike. For example, in the United States, coastal areas represent less than 17% of available land area and serve as home to over 53% of the population. In Michigan, a 12% population increase is projected to lead to a 63-87% increase in the amount of land devoted to urba use. The concentration of commercial and recreational activities associated with our intense use of lakes, rivers, and coastal areas is taking a toll on the fishery benefits we can obtain from these systems. Many scientific diagnoses of declining fisheries species and their habitats along U.S. coasts point to upland and tributary sources near areas with increasing human population, development, and expansion of impervious surfaces. Resulting stressors, such as increased nutrient input, habitat loss, changing hydrological patterns, and exacerbated erosion are negatively impacting fish health and sustainability. As fisheries managers are faced with managing ever changing populations of fish, a broader approach may be necessary for proper management. Ecosystem based approaches must incorporate land use processes by better understanding and addressing the impacts of land use patterns, planning, and decision making. This symposium will assemble case studies to provide examples and explain the inherent link between land use, water quality and fisheries. The findings and presentations will help improve our understanding of factors that influence resources in coastal, lentic, lotic and estuarine systems. We will explore the actions taken, available tools, community engagement, and discuss cross organizational approaches needed to manage fisheries beyond the aquatic zone.

Climate and Fisheries: Responses of a Socio-Ecological System to Global Change

Abstract: Over the coming century, climate change is predicted to dramatically alter our oceans through ocean acidification, warming temperatures, altered ocean currents, and other changes. These changes will impact marine species and the food webs that support local and global fisheries. In parallel, human societies and the activities they pursue are projected to change dramatically. Population growth, rising gas prices, technology, and globalized economic markets will all affect the spatial and temporal patterns of fishing, the species they target, and the ways in which the social benefits of fisheries are distributed. How do these factors – social and ecological – work in concert and affect each other in a warming and souring ocean? In this session, we invite contributions that address the impacts of climate and societal trends on the future status of fish and fisheries, particularly those that address important feedbacks and coupling between social and ecological systems. We are particularly interested in work that addresses the ecological changes expected from climate change, the social changes over the next 50-100 years that will transform fisheries, and the ways in which social interactions can mitigate or amplify the effects of climate change. Will growing populations and warming waters drive large-scale fisheries declines or open new opportunities? What are the costs of these transitions and how to we plan for them? How do markets and societies deal with changing food webs and shifting ranges? How do we design individual incentives to facilitate adaptation to climate change? We anticipate that these approaches will be both theoretical and empirical, and we also hope to discuss pro-active approaches to manage fisheries and marine ecosystems in the face of these transformations.

Geomorphic-Based Design Responses to Natural Disasters

Abstract: The American Fisheries Society (AFS) Bioengineering Section (BES) is currently writing a position paper relating to appropriate geomorphic-based design responses to natural disasters, when dealing with rivers.  The recent hurricane in the northeast and significant flooding throughout the nation have highlighted the severity of this issue.  Engineering and scientific advancements in the field of river restoration are often set aside when communities and states need to respond quickly to safety and infrastructure issues immediately following a natural disaster.  Enhancement made through decades of carefully planned river management can easily be bulldozed away within days after a natural disaster, with little consideration given to environmental regulations.  While swift responses are critical following a natural disaster, this session will focus on many of the lessons learned and precautions that could be taken to ensure that more appropriate geomorphic-based design responses are implemented following a natural disaster.

Constructing Fish Passage Projects

Abstract: As fish passage practitioners many of us tend to focus on the investigation, planning, and design of quality fish passage projects. Although designing the fish passage project is a key component, constructing the project to meet design objectives is also an equally critical aspect of any project.  Conveying the intent of the design, collaborating with contractors, dealing with budget shortfalls, real-time conflict resolution, inspection, and verification of key design components are challenging.  Add on the fact that many fish passage projects include one-of-a-kind applications and many contractors don’t have adequate amounts of fish passage construction experience to begin with.  All of these factors play a part in the successful or unsuccessful implementation of fish passage projects long after the design is complete.  This session will focus on the variety of approaches that practitioners use to monitor, document, evaluate, and react appropriately to scenarios that occur at the construction site. Past case studies, lessons learned, and tools of the trade will be presented and discussed which will benefit those of us who spend time on a construction site as well as those who focus on design development.
