Walleye

From U.S. Geological Survey (USGS):

Warming water temperatures from climate change will likely mean fewer walleye – a preferred fish for many anglers – and more largemouth bass in midwestern lakes, according to a new study supported by the USGS National Climate Change and Wildlife Science Center. The researchers examined more than 2,100 Wisconsin lakes and found that walleye populations have been declining for the past 30 years, a trend that is predicted to continue into the future. On the other hand, largemouth bass, which prefer warmer lakes, are anticipated to become more abundant. These changes will have implications for the freshwater sport fishing industry, which is valued at more than $1.5 billion in Wisconsin. Learn more:http://go.usa.gov/xKtAD
