Gas Supersaturation Suspected As Cause of Massive Western Kentucky Fish Kill
Biologists say they may know the cause of a massive fish die-off last month in the Cumberland and Tennessee Rivers in Western Kentucky.
Paul Wilkes with the Kentucky Department of Fish and Wildlife Resources says the Asian carp show signs of having bubbles in their gills. He says the bubbles happen when a body of of water develops gas supersaturation. He says it often happens below dams -- in this case the Lake Barkley dam and the Kentucky Lake dam.
An estimated 500,000 Asian carp were found dead April 23rd. Biologists from several agencies are still examining specimens from the fish kill.
