ROGERSVILLE, Ala. (April 6, 2014) Researchers are trying to answer the key question of what’s in the water to give people who enjoy America's $48 billion recreational fishing industry information about what lies beneath the surface.
Biologists are studying the 11 largest lakes in the Tennessee Valley Authority system using a method called "electrofishing," which involves charging the water with electricity to stun fish and make them float to the surface.
The charge leaves the fish in a zombie-like state, but researchers say they almost always recover.
Study data provides biologists with valuable information about how to best manage the TVA lakes, which are some of the most biologically diverse in North America.
