State of the Science on the Effects of Climate Change on North American Inland Fishes

Assessing the Impact of Climate Change on Global Inland Fisheries


Start Date
End Date
Release Date


Changes in the Earth’s climate are expected to impact freshwater habitats around the world by altering water temperatures, water levels, and streamflow. These changes will have consequences for inland fish – those found within lakes, rivers, streams, canals, reservoirs, and other landlocked waters – which are important for food, commerce, and recreation around the world. According to the U.S. Fish and Wildlife Service, in 2011, 33.1 million people fished and spent $41.8 billion in the United States alone. Yet to date, little comprehensive research has been conducted to investigate the effects of climate change on inland fisheries at a large scale. The aim of this project was to summarize the current state of knowledge, identify [...]

Changes in the Earth’s climate are expected to significantly impact freshwater aquatic habitats in North America and around the world by changing water temperatures, water levels and streamflow. These changes will have an effect on inland fish species, and their associated fisheries, and consequently will impact recreational and subsistence fishers, human communities, and economies. Inland fish are especially vulnerable to climate change because they have limited habitat availability and they have a more direct link with terrestrial systems, human land use patterns, and human water use than fish in marine ecosystems (and human activities are already threatening and weakening inland fish in many areas). With a changing climate, some inland fish may become stressed, resulting in weaker immune systems and lower reproductive success, whereas other inland fish species may actually fare better and become more competitive. To date, little comprehensive research has been conducted to investigate the climate change effects on inland fisheries at a large scale. The objective of this project is to synthesize our understanding of how climate change may affect inland fisheries. Project researchers are actively (a) identifying the key data and knowledge gaps related to how climate change will affect inland fisheries and (b) examining the questions: “do current and future changes differ by region?” and “do these changes differ by species, habitat type, or other traits?”.
