Walleye are valuable sport fish across the Great Lakes basin. In Lake Erie, this is no different as the lake is commonly called the “walleye capital of the world.” But keeping the lake full of abundant walleye stocks takes a lot of work.
The effects of climate change are changing the distributions of fish stocks around the world, according to research led by Rutgers University.
Fisheries biologists have been trying to help endangered Chinook salmon in the Sacramento River for a few years now. But last year, after a horrible rise in summer water temperatures, about 95 percent of those fish that had been stocked were killed.
Seafood is a heavily relied upon resource for protein and nutrients globally--and the ever-decreasing number of fish found in the ocean, streams, lakes, and rivers is making people anxious.
