NC1189 In-Person Meeting Notes - 18 Aug 2023.docx.pdf

Brief Summary of Minutes

Broadly, the purpose for this meeting was to allow project participants to get to know one another and to plan for efforts to address our project goal and objectives in the coming years, which includes determining how fisheries function as coupled human and natural systems (CHANS). Because membership of the current project team includes individuals who were members of the previous NC1189 team (engaged before 2022) along with multiple new members, we began the meeting by reviewing the goal and objectives of our proposal. This was followed by short lightning talks from each member so that we could learn about members' research expertise and interests. Following those talks, Andrew Carlson provided an overview of the CHANS framework and discussed the various components of CHANS (scale, heterogeneity, feedback loops, time lags and legacy effects, nonlinear dynamics with thresholds, surprises). We then had a discussion led by Mazeika Sullivan and Gayle Zydlewski which described previous efforts to incorporate the perspective of Native American tribes into the work as well as the challenges and opportunities of doing so in our current efforts. We then began discussing details of a survey that would be sent to natural resource professionals that would in part assess their understanding of fisheries as CHANS and also serve as an education tool. The meeting concluded with a short discussion on identifying some funding opportuntiies for our project.

Accomplishments

SHORT-TERM OUTCOMES We are collaborating with several different angling groups to quantify the impact of angling practices on individual fish and fish populations with hope of improving regulations that sustain healthy fisheries, particularly in the future when considering climate change. We are collaborating with state and federal agencies to develop a risk assessment tool for invasive species range expansion via a network of rivers, streams, irrigation canals, and other connection points in the Great Plains that is building a compendium of physical connections among waterways, early detection data from eDNA, and human management practices that facilitate connections. We are working with the National Park Service to develop an early detection and rapid response (EDRR) framework for aquatic ecosystems in the agency’s Midwestern region. In this region, increased air and water temperatures and intensifying drought risk will likely accelerate the rate of native species decline, opportunistically favoring invasive species. We are working with the US Geological Survey Nonindigenous Aquatic Species Program to identify a set of streams and lakes to monitor that are optimal for establishment of aquatic invasive species based on habitat characteristics of those waterbodies. OUTPUTS In our proposal, we identified multiple outputs that we expected to achieve through this effort.  These are listed below. <ol> <li>Research framework</li> </ol> Our team is developing a survey focused on fisheries as CHANS to send throughout our professional community.  This survey will assess respondents' understanding of fisheries as CHANS, and, based on responses, we expect that it will expand our own understanding and inform additional investigations. We are developing a framework to link creel survey and mobile device-generated data to inland fisheries conditions, which will allow us to link human activity to fish assemblages, invasive species, water quality, and climate. It will be able to draw on the database described in output #3. This framework is a collaboration between social and fisheries scientists and piloted with data on reservoir fishing. We are developing a framework for understanding factors associated with resilience and transformation of social-ecological systems, and it will be tested on fisheries case studies. We are conducting a comprehensive, structured literature review supplemented by key informant interviews about climate change impacts and adaptations in freshwater systems (fisheries as well as aquaculture), the results of which will inform the development of a framework for studying climate impacts and adaptations in freshwater fisheries and aquaculture systems. We are mining historical self-reported creel data for brook trout fisheries in the Adirondack Park to assess how angling efforts and outcomes have shifted over the last 50 years.  In this region, warming in the summer has reduced trout angling during the period of peak park visitation, and displaced both effort and catch into the spring and fall.  This limits overall angling opportunities as a reflection of intersections between ecosystem changes, fish behavior, and angler responses.  Warming may also be facilitating species invasions and shifts in angling targets in this landscape. We are looking at the response of native and invasive aquatic plants (fish habitat) to carp removal and alum treatments to improve water clarity and how this affects or requires additional plant management. We are also looking at the decision-making processes and integration across disciplines in managing these systems which have been impacted by climate change and human development. We are assessing the effects of harvest, escapement, and environmental conditions on reservoir sportfish populations across a range of reservoirs with various water control structures. We are developing ecological and social–ecological models to advance knowledge of Florida fisheries as coupled human and natural systems (e.g., Largemouth Bass, Black Crappie, Smalltooth Sawfish, Bluenose Shiner) in the context of stressors such as land-use change, species invasion, and groundwater withdrawal. Over a decade of data are being aggregated and synthesized to empirically characterize factors affecting survival, reproduction, and population trends of diadromous coastal and inland species - particularly dam removal. Data continue to be collected from individual fish that are carrying long-lived (10 year) tags. These data are being used in species management as well as informing the framework development for the multi-state coupled human and natural systems research that are beyond the specific local fisheries research in Maine. <ol start="2"> <li>Best practices</li> </ol> We have defined how different angling practices across temperatures can impact fish populations, identifying situations where water conditions may be exceeding the tolerable limits for certain fishes, suggesting the need for management intervention. We have created co-developed decision-support, including integration of spatial data into an interactive map to serve as a knowledge base and creation of a central data repository for non-spatial information to inform coastal development, with a focus on tidal power and fisheries. <ol start="3"> <li>Database</li> </ol> Stream fish data have been acquired from state agencies across the US.  These data have been integrated into an existing dataset to characterize assemblages sampled in a consistent manner at tens of thousands of locations in the US. We and collaborators are developing a database of aquatic plant point intercept surveys in Minnesota and Wisconsin and another data base of watermilfoil genotypes and known responses to herbicide treatments.  These data could be linked to or accessed from project data base or project members We are working to connect coastwide datasets on Shortnose and Atlantic Sturgeon populations on the east coast of the US. <ol start="4"> <li>Data needs</li> </ol> Nothing to report yet. <ol start="5"> <li>Assessment</li> </ol> Using information on characteristics of locations where aquatic invasive species have established previously across the US, we have modeled the likelihood of invasions by a set of new species to aid in developing watch lists for state and federal agencies.  This was also described as a short-term outcome but will form the basis of a larger assessment focused on invasive species. <ol start="6"> <li>Synthesis comments</li> </ol> We are conducting a comprehensive, structured literature review supplemented by key informant interviews about climate change impacts and adaptations in freshwater systems (fisheries as well as aquaculture), the results of which will inform the development of a framework for studying climate impacts and adaptations in freshwater fisheries and aquaculture systems. <ol start="7"> <li>Meetings and workshops</li> </ol> We held our first NC-1189 meeting on August 18, 2023 in East Lansing, Michigan.  Some members of the team were able to join in person while others attended virtually. We hosted a workshop in October 2023 with MSU, FAO, and world experts on ecosystems restoration, with the goal of exploring guidelines for doing ecosystems restoration that supports livelihoods and food security, among other social objectives. The framework described in output #1 will be presented at the World Fisheries Congress, March 3-7 in Seattle, Washington. We are organizing a symposium on the physiological control of invasive species at the Fish Physiology meeting (International Congress on the Biology of Fishes), June 23-27, 2024 in Ann Arbor, Michigan. We are in the process of planning for a symposium to occur at the American Fisheries Society 2024 annual meeting to highlight work showcasing fisheries as CHANS. 8.

MILESTONES In the next project year, we anticipate conducting the survey of fisheries professionals to gauge their understanding of fisheries as CHANS, including consideration of similarities and differences in understanding by profession and region.  We anticipate that this survey will clarify additional areas that we could work in to better understand relationships between fisheries and human systems, and we expect that this survey will provide a baseline of information for more clearly developing an overarching framework (refer to Output 1). We are also organizing a session for the American Fisheries Society meeting in September 2024.  In this session, participants will present on their respective research projects but will be asked to incorporate the emphasis of the fishery or system that they work on using a CHANS framework. We have been having near monthly calls with the project team, and on our next call in February 2024, we will begin discussions to plan our next in-person meeting.

Brief Summary of Minutes

Objectives for this meeting included reconnecting members with one another and learning more about the diverse expertise and skills of group members along with the various projects that people have been working on. We also reviewed our project objectives and timeline and spent substantial time discussing preliminary feedback provided through a pilot group on our survey intendend to better understand how fishery professionals understand fisheries as coupled human and natural systems (CHANS). Because we spent most of the meeting working on the survey, our meeting notes are limited. Our meeting occurred a few days before the beginning of the Annual Meeting of the American Fishery Society (AFS), and we were working to roll out the final version of the survey at a session organized to explore fisheries as CHANS during AFS. We discussed other professional societies and networks that we would engage to ensure that more diverse perspectives were included in the survey (e.g., Society for Freshwater Science, InFish network). We also discussed some ideas that could build on the survey once it was complete, including organzing focus groups, and we discussed the logistics of project management for the coming year including report writing and future meeting planning.

Accomplishments

I. Short-term Outcomes  The most relevant short term outcome generated from this project is the growing understanding of fisheries as coupled human and natural systems (CHANS).  This is important because this framework formally acknowledges the links between fisheries and their habitats with society.  This has been occurring through regular engagement of team members with each other through our monthly meetings, engagement with our peer community through the session organized at the American Fisheries Society Annual meeting in September 2024, and through the survey that we shared across our professional networks through 2024 (and into 2025).  Results of the survey are being analyzed currently, and preliminary results lend support to this outcome.   II. Outputs and Activities (Identified in our Research Proposal)  This section describes both outputs and activities organized by the objectives in our research proposal.   <ol> <li>Research framework: A collaborative, coupled human and natural systems research framework for investigating interactions between invasive species, climate change, and inland and marine fisheries and aquatic resources.</li> </ol>  Our team has developed a survey that presents fisheries as CHANS, and we have distributed the survey throughout our professional community.  This survey will assess respondents' understanding of fisheries as CHANS, and, based on responses, we expect that it will expand our own understanding.   <ol start="2"> <li>Best practices: A description of best practices for how the above framework can be applied for different fisheries.</li> </ol>  We have one example of best practices informed by the CHANS framework so far.  This has been achieved by colleagues from Cornell.  We have evaluated the climate resilience traits, growth rates, and survival rates of six strains of brook trout that are stocked into New York waters and are using the results to advise NYSDEC and private hatcheries on how strain selection could be used to adapt stocking practices to support self-sustaining cold-water fisheries.  We have now submitted a manuscript describing the differences in performance among strains (Detmer et al. in review), and we are sharing those results with our state partners. We also leveraged the Multistate project network and federal agency colleagues to gather brook trout tissue samples to sequence the whole mitochondrial genome of wild and stocked strains of brook trout throughout their range, which could inform future surveys of the outcomes of stocking programs using eDNA.   <ol start="3"> <li>Database: A database that integrates biological, ecological, and socio-economic data to facilitate analyses. To the extent practical, individual datasets comprising the database will be linked to a common spatial and/or analytical framework.</li> </ol>  Stream fish data have been acquired from state agencies across the US.  These data have been integrated into an existing dataset to characterize assemblages sampled in a consistent manner at tens of thousands of locations in the US.  Additionally, we have updated a database describing natural and anthropogenic influences on stream fishes and their habitats.  These data will be made publicly available in the coming year, but nearly all of the fish data and all of the environmental variables are available to the project team.   <ol start="4"> <li>Data needs: A prioritized list of data requirements for interdisciplinary questions that cannot be answered yet due to a lack of data.</li> </ol> <ul> <li> Colleagues from Cornell have identified a lack of data on how climate change is altering the nutritional value of inland fishes for human consumption, and we conducted an initial survey of omega-3 fatty acids, selenium, and mercury in brook trout across lakes representing a range of climate-induced oxythermal stress. We found a surprisingly wide range of concentrations of all three analytes, and both selenium and mercury were linked to oxythermal conditions. We infer that climate change can strongly mediate the nutritional value of fish, but in complex ways.</li> </ul>   <ul> <li>Colleagues from Michigan State University have attempted to model locations of reefs throughout the Laurentian Great Lakes. Presently, locations of reefs were compiled through anecdotal descriptions, but not comprehensive attempt to identify reefs has ever occurred limiting manager’s ability to strategical restore degraded reefs or monitor fish spawning activity.</li> </ul>   <ul> <li>We anticipate generating a more comprehensive list of data based on information provided through our survey as well through a national-scale assessment of stream fish habitat.</li> </ul>   <ol start="5"> <li>Assessment: An updated assessment of ecological and socioeconomic effects of climate change and invasive species on inland and marine fisheries. This assessment will integrate data across disciplines to gain robust insights into climate change and invasive species problems in order to make specific interdisciplinary management recommendations for mitigating detrimental effects on fisheries.</li> </ol> <ul> <li> Using information on characteristics of locations where aquatic invasive species have established previously across the US, we have modeled the likelihood of invasions by a set of new species to aid in developing watch lists for state and federal agencies.</li> </ul>   <ul> <li>We have used angler self-reporting to assess how both angling efforts and catch rates have changed over the last 40 years in terms of choice of lake and effort timing, with the goal of understanding whether independent responses of anglers and fishes to changing environmental conditions are likely to enhance or constrain the sustainability of cold-water fisheries.</li> </ul>   <ul> <li>Using data collected by the National Park Service Heartland Inventory and Monitoring network, we analyzed fish community data across Midwestern National Parks to investigate patterns of biotic homogenization, a phenomenon indicative of species introductions and loss of biodiversity. In this region, increased air and water temperatures and intensifying drought risk will likely accelerate the rate of native species decline, opportunistically favoring invasive species.</li> </ul>   <ul> <li>Determined broad and fine scale drivers of fish assemblages in the Prairie Pothole region and identified environmental cut-offs for changes in species assemblages. Environmental cut-offs such as overwinter temperature and amount of natural land in watersheds were most predictive of fish assemblage. Changing water levels in the Prairie Pothole can also cascade from impacts on fish to impacts on humans. An analysis of Devil’s Lake, a large lake in North Dakota that has dramatically risen in water levels, revealed that higher waters were related to increased angler efforts. We are also using fish bioenergetics to examine changes in fish scope for growth over 40 years. These modeling efforts are currently in progress, but analyses completed thus far reveal spatial clusters of increasing habitat quality for cool-water fishes in locations such as the Upper Peninsula of Michigan. Habitat quality appears to be declining for many cool-water species along the East Coast.</li> </ul>   <ul> <li>We have investigated movement ecology and survival of invasive carp and native sportfishes in relation to key environmental variables (temperature, discharge) to assess factors associated with population connectivity and sustainability. These results will help guide efforts for controlling invasive fishes while promoting the existence of sport fisheries.</li> </ul>   <ul> <li>Multiple projects focused on understanding CHANS at various geographic scales. These include (1) understanding restoration impacts on hybridization with non-native species under different restoration scenarios and (2) climate change resiliency and adaptive capacity of inland fishes. (1) Is mostly related to a U.S. Forest Service grant which looks at comparative stream network connectivity across different species under different future scenarios that have been identified by stakeholders. This project is helping to build an overall model to understand the balance between increasing river habitat to improve populations while minimizing invasive species impacts. We collected environmental DNA in 2024 and worked with existing genetic samples across the basin of the grant to be paired with existing environmental data in the area. Adams et al. 2024 also used eDNA and traditional surveys to understand conservation outcomes at the aquatic community level, and although not included in the paper, three trout species were surveyed. (2) Captures two projects. The first is using genetics and environmental data to look for associations between the two to understand how local adaptation may be accounted for within our walleye hatcheries. These data will also be used to project how hatchery practices may need to change. The second is focused on local adaptation and land use management practices for the conservation of Yellowstone cutthroat trout, which uses individual-based models that incorporate demography, genetics, and climate change with the presence of three non-native trout species.</li> </ul>   <ol start="6"> <li>Synthesis Comments: A synthesis of existing work that reveals how individual and organizational responses to invasive species and climate change affect inland fisheries and aquatic resources.</li> </ol> <ul> <li> We have analyzed the ecological outcomes of a two-decade project to control smallmouth bass invasions, and demonstrated that bass life history has evolved in response to intensive selection from our management practices. Nonetheless, we find positive responses of many native species to the suppression of predatory bass, though some community members required >15 years to show a measurable demographic response.</li> </ul>   <ul> <li>Surveyed existing preventative actions (Regulation, Education, Inspections) across the United States related to Aquatic Invasive Species (AIS) in the live bait trade. We found that in some regions of the United States, high values fisheries that do not rely on live bait (e.g., trout fishing with flys) have allowed states to heavily regulate the live bait trade. In other regions such as the SouthEast where aquaculture is a leading economic driver, regulation of the live bait trade is less frequent. Education and inspections are heavily used for prevention in the Great Lakes region.</li> </ul>   <ul> <li>Also completed review of the drivers of introduced fishes in prairie streams wherein we overview impacts of introduced species, how climate change is likely to influence future introductions, and suggest management actions and future research directions.</li> </ul>   <ul> <li>Currently three review/synthesis papers are in prep. The first two are focused on adaptive capacity, with both papers providing context and recommendations related to the social system and have direct management implications. The third paper is a review of the integration of genetics into species action plans in the U.S. and Canada, and includes a review of the organizations involved in management decision making.</li> </ul>   <ol start="7"> <li>Meetings and workshops: Meetings and workshops that convey information on how to influence individual behavior and organizational responses to invasive species and climate change in ways that benefit the management of inland fisheries and aquatic resources.</li> </ol> We have met virtually nearly every month since our project was initiated.  Additionally, we organized a symposium at the American Fisheries Society 2024 annual meeting to highlight work showcasing fisheries as CHANS. We also hosted an annual NC1189 meeting where we discussed project objectives and progress towards meeting them.   <ol start="8"> <li>Publications and presentations: Peer-reviewed publications, research reports, and professional presentations communicating the results of this project.</li> </ol> Peer-reviewed publications Adams, A.

Impact Statements

1. Improved tools, datasets, and guidelines for use by federal and state agencies, non-governmental organizations, and other stakeholders to detect, predict, and mitigate the individual and interactive effects of climate change and invasive species on fish communities and aquatic ecosystems at local, regional, and national scales.
2. Forecasting the interacting effects of climate change and invasive species on inland and marine fisheries and aquatic resources will provide policymakers with improved understanding needed to make informed decisions about coupled human and natural systems, allowing us to anticipate and minimize ecological and socioeconomic losses, as well as to potentially mitigate for any losses. Increases sustainability of recreational and commercial fisheries in light of the individual and interactive effects of climate change, invasive species, and socioeconomic factors that influence aquatic communities.
3. Improved communication about threats to and condition of inland and marine fisheries globally.
