"Inland fish play critical roles in North American ecosystems and economics: In the U.S. alone in 2011, freshwater anglers spent more than $30 billion on their hobby, generating $73 billion in economic output. And fish help keep nature in balance as they feed on aquatic plants and animals and in turn provide sustenance to iconic species such as eagles, bears and osprey.
It’s no surprise, then, that as climate changes, 30 experts gathered last year in Bozeman, Montana, to explore implications for the well-being of North American fish populations.
Reporting earlier this month in a special issue of Fisheries magazine, the researchers summarized a range of actual and anticipated changes in North American inland fish identified by 31 previous studies. The changes relate to shifts not only in temperature but also in other climate-related environmental factors such as salinity, oxygen levels, and size and connectedness of water bodies."
