LOUISVILLE (WATE) - Local fishermen got a chance to ride along with TVA officials to survey the fish population Wednesday. Crews were out at Fort Loudoun Reservoir in Blount County checking for any changes with the fish.
"The electrical field causes the fishes muscles to tense up. As they tense up, the swim bladder floats them to the surface," said John Justice, TVA fisheries biologist.
Then, he said they scooped the fish up and held them in an aerated tank to be checked out.
He said the fish are usually back to normal two or three minutes after being pulled from the water, and over the past few years, he's seen a trend of more sports fish in our rivers.
TVA will share the data collected with state agencies and schools.
