Lake Michigan Yellow Perch Bounce Back After Commercial Ban

For decades, commercial fishing for yellow perch was allowed in southern Lake Michigan. This persisted until 1996 when it was outlawed, giving perch stocks there some time to recover. Scientists had for some time assumed that this fishing ban would not affect the reproduction cycles of the perch quickly and that they were going to need a long time to revert back to the cycles they relied on before commercial fishing ever started. But new research led by scientists at Purdue University finds that maturation schedules of yellow perch in southern Lake Michigan are much more resilient than had been previously thought possible.

Colorado River Fish Contain Levels Of Selenium, Mercury

Scientists from many institutions were involved in the years-long work, full results of which have been published in the journal Environmental Toxicology and Chemistry. It was led by the U.S. Geological Survey, but perhaps the contributors from Idaho State University got the best end of the stick. They were looking into the food webs of the river to evaluate concentrations of selenium and mercury gathering in fish.
