State’s fight against Asian carp scales up

WATE: Commercial fishing pulls out 10 million pounds of exotic carp from Tennessee River system

If you never thought there’d be an Asian carp commercial fishery in Tennessee waters, you were wrong.

Tennessee Wildlife Resources Agency’s Asian Carp Harvest Incentive Program has yielded 10 million pounds of the exotic fish since 2018, the bulk caught downstream on the Tennessee River system at Kentucky and Barkly reservoirs. The fish has been spotted as far upstream as Knox and Anderson counties.

The Tennessee Valley Authority and TWRA are experimenting with acoustic barriers to prevent further upstream spread of the fish, which compete with native fish for food and habitat.

“There are four types of Asian carp: bighead, silver, black and grass,” WATE reported. “Experts say the species threatens to disrupt aquatic ecosystems and starve out native species due to their ability to out-compete native species for food like plankton.”

So what do fishermen do with 10 million pounds of carp?

It can be sold to wholesalers for distribution abroad and also makes for really good fertilizer.
