Officials aim to install system to block invasive fish

October 1, 2018

FRANKFORT, Ky. (AP) — Kentucky officials say they are aiming to install a riverbed bubbler and sound system in Lake Barkley early next year as an environmentally friendly way to block the spread of an invasive fish.

The Kentucky Tourism, Arts and Heritage Cabinet said the technology will be tested below Barkley Dam in western Kentucky. Several agencies in Kentucky and Tennessee are combining funding, technology or staff to move forward with the project to stop Asian carp.

The agency says the Asian carp is a concern throughout the Mississippi River basin, including the Tennessee River, which forms Kentucky Lake, and the Cumberland River, which forms Lake Barkley.

The agency says the Bio-Acoustic Fish Fence creates a curtain of bubbles, which, along with a powerful sound signal, produces a “wall of sound” underwater.
