Fish

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.

Susceptibility of Rio Grande Cutthroat Trout to Displacement by Non-Native Brown Trout and Implications for Future Management

The Rio Grande cutthroat trout is New Mexico’s state fish; but habitat loss and non-native trout invasions threaten the persistence of this fish throughout the remaining 12% of its historic range. Stakeholders, including state agencies, federal agencies, Tribal nations, Pueblos, and private groups are particularly concerned about the impact that non-native brown trout have on native cutthroat trou

Synthesizing Climate Change Impacts on Wildlife Health and Identifying Adaptation Strategies

Changing climate conditions could have significant impacts on wildlife health. Shifts in temperature and precipitation may directly affect the occurrence of disease in fish and wildlife by altering their interactions with pathogens (such as the bacterium that causes Lyme disease), helping vectors like mosquitoes and ticks expand their range, or speeding up the time it takes for a parasite to devel

The U.S. Inland Creel and Angler Survey Catalog (CreelCat): A Database and Interactive Tool for Inland Fisheries Management and Research

Inland recreational fishing, defined as primarily leisure-driven fishing in freshwaters, is a popular past-time in the USA. State natural resource agencies endeavor to provide high-quality and sustainable fishing opportunities for anglers. Managers often use creel and other angler-survey data to inform state- and waterbody-level management efforts. Despite the broad implementation of angler survey

Understanding Climate Impacts on Native and Invasive Fish for Conservation, Management, and Economic Goals in the Northern Rockies

As the origin of three major basins that drain the Columbia, Missouri, and Saskatchewan rivers, Montana is the hydrologic apex for North America. The Northern Rocky Mountain region is home to some of the last remaining interconnected habitats for many native fishes, including the threatened bull trout and native westslope cutthroat trout. The Northern Rockies are also experiencing rapidly changing

“Hyperscale” Modeling to Understand and Predict Temperature Changes in Midwest Lakes

Many inland waters across the United States are experiencing warming water temperatures. The impacts of this warming on aquatic ecosystems are significant in many areas, causing problems for fisheries management, as many economically and ecologically important fish species are experiencing range shifts and population declines.

Balancing Water Usage and Ecosystem Outcomes Under Drought and Climate Change: Enhancing an Optimization Model for the Red River

Hydrologic drought and declining water availability are among the foremost stressors of stream ecosystems in the Red River basin. Resource managers face the challenge of apportioning scarce water resources among competing uses, but they lack a systematic framework for comparing the costs and benefits of proposed water management decisions and conservation actions. In 2016, Co-PIs Neeson and Moren

Climate Change Impacts on Invasive Species in the Northwest: A Synthesis and Path Forward

Invasive species have increasingly severe consequences for ecosystems and human communities alike. The ecological impacts of invasive species are often irreversible, and include the loss of native species and the spread of disease. Implications for human communities include damaged water transportation systems, reduced crop yields, reduced forage quality for livestock, and widespread tree death -

Development of the Wildlife Adaptation Menu for Resource Managers

The Climate Change Response Framework is an example of a collaborative, cross-boundary approach to create a set of tools, partnerships, and actions to support climate-informed conservation and land management. Historically, this effort has focused on the needs of forest managers and forestry professionals. In recent years, however, there has been increasing demand for science and tools to address

Evaluation of Sustainable Water Availability in Drought Prone Watersheds in Southeastern Oklahoma

During the severe drought of 2010-2015, several communities in southeast Oklahoma almost ran out of water. Some of these communities rely on streams and rivers as their sole source of water and when these sources almost ran dry, it left them searching for alternatives and wondering how to continue growing, economically, with this water uncertainty.
