Fish and Climate Change (FiCli) Database: Informing climate change adaptation and management actions for freshwater fishes
Recreational and inland fisheries are invaluable to their local communities, providing economic support, food security, and enhanced social connection with natural areas. CASC scientists examine how climate change is contributing to aquatic habitat loss, increased river and lake temperatures, and invasive aquatic species to help fisheries adapt to these changes. Explore our science on fish below.

Understanding Brook Trout Persistence in Warming Streams
Cold-water adapted Brook Trout were historically widely distributed – ranging from northern Quebec to Georgia, and from the Atlantic Ocean to Manitoba in the north, and along the Appalachian ridge in the south. However, studies show that due to factors associated with climate change, such as increased stream temperature and changing water flow, the number of streams containing Brook...
Webinar: Variable Warming in Lakes of the Upper Midwest and Implications for Sport Fish
Check out this webinar to learn more about how warming temperatures are affecting lakes in the Midwest and the fish they support.
Adirondack Fish Conservation: Safeguarding Summer Suckers, Understanding Minnow Diversity, Limiting Smallmouth Bass Invasions, Developing Climate-Adapted Stocking
Overview Fishes of the Adirondack Park face numerous challenges. Summer Suckers are the only endemic vertebrate yet have suffered major range reductions, so we are analyzing their genome, body shape, and spawning timing to verify their uniqueness and current range. Warming patterns are expected to shift their spawning earlier, potentially intersecting with their recent ancestor (White...
Analysis and Visualization of Climate Information to Support USFWS Species Status Assessments
Under the Endangered Species Act, the U.S. Fish and Wildlife Service (USFWS) must evaluate the status of at-risk plants and animals in the U.S. A Species Status Assessment (SSA) is a scientific assessment prepared for each at-risk species to help inform a range of management decisions under the Endangered Species Act. SSA’s are currently needed for more than 350 species, 250 of which are...
Assessing the Benefits and Vulnerability of Current and Future Potential Ecosystem Services of the Nisqually River Delta and other Puget Sound Estuaries
The Nisqually River Delta represents the largest wetland restoration in the Pacific Northwest. The restoration resulted in a 50% increase in potential salt marsh habitat. The Delta supports threatened salmon fisheries, large populations of migratory birds, and provides unique opportunities for recreation. The Delta also provides multiple ecosystem services, which are the benefits that...
Developing A National Framework for Incorporating Climate Change Refugia into Conservation and Adaptation Planning
The impacts of climate change are widespread and accelerating. As natural resource managers are tasked with maintaining and protecting species and ecosystems, options for minimizing the impacts of climate change are needed. One option for climate adaptation focuses on resistance, which seeks to preserve, as much as possible, the historical structure, composition, and function of an...
Evaluating Species’ Adaptive Capacity in a Changing Climate: Applications to Natural-Resource Management in the Northwestern U.S.
Natural resource managers are confronted with the pressing challenge to develop conservation plans that address complex ecological and societal needs against the backdrop of a rapidly changing climate. Climate change vulnerability assessments (CCVAs) provide valuable information that helps guide management and conservation actions in this regard. An essential component to CCVAs is...

Fish Habitat Restoration to Promote Adaptation: Resilience of Sport Fish in Lakes of the Upper Midwest
Many Midwestern lakes are experiencing warming water temperatures as a result of climate change. In general, this change is causing coldwater fish species such as cisco and coolwater species such as walleye to decline. Meanwhile, warmer water species such as largemouth and smallmouth bass are increasing as temperatures warm. However, some fish populations are more vulnerable to these...
Northeast Regional Invasive Species and Climate Change (RISCC) Management
Overview Invasive species and climate change represent two of the five major global change threats to ecosystems. An emerging initiative of the Northeast Climate Science Center aims to develop management-relevant research to improve invasive species management in the face of climate change. Through working groups, information sharing and targeted research, this project addresses the...
The Potential Impacts of Climate Change on River Food Webs and Salmon Productivity in Southeast Alaska
Salmon that spawn and rear in Southeast Alaska watersheds are critically important to the region’s economic vitality and cultural identity. An estimated 90% of rural households in Southeast Alaska use salmon. Environmental changes that compromise the ability of these streams to support salmon could have dramatic consequences for the region. In particular, there is concern that climate...
