Late final week, the Tennessee Wildlife Assets Company (TWRA) responded to experiences of enormous numbers of lifeless catfish floating close to a rattling on Chickamauga Lake, a 36,000-acre reservoir northeast of Chattanooga. After combing a 32-mile stretch of shoreline, TWRA officers stated they discovered roughly 300 lifeless channel catfish averaging simply over a pound in weight. As a result of superior decomposition, the TWRA workers declined to gather samples, a latest press launch states, and the reason for loss of life has but to be decided.

Within the press launch, the company stated that all the catfish died on the similar time, and there have been no apparent indicators of illness or trauma.
Whereas TWRA biologists are nonetheless investigating the case, they imagine that the die-off found over the weekend was an remoted occasion. And since it was restricted to only one species of fish, they’ve formally dominated out chemical compounds, viruses, and bacterial sources as potential causes of loss of life. “This seems like a big quantity, however within the organic world, it isn’t,” stated Bobby Brown, the state’s Aquatic Habitat Safety Biologist. “There are a number of clues that permit us to know this incident shouldn’t be attributable to chemical compounds, micro organism, or a virus.”
Richard Simms is a catfish information on Chickamauga Lake and different waterways round Chattanooga who reported the die-off to the TWRA. He tells Discipline & Stream that the entire variety of lifeless channel catfish is probably going far bigger than the 300 or so counted by TWRA brokers.

“There are credible experiences from different states of a bacterial an infection referred to as columnaris, which will be particular to channel catfish.

Folks do have to be involved and report incidents to the officers, the scenario must be monitored. However there’s no must panic.”
