摘要: Recent lock closures at Barkley Lock and Dam in western Kentucky are helping researchers determine more about the movements of invasive Asian carp and how best to contain their spread. In November 2019, officials with the U.S. Fish and Wildlife Service and partner agencies installed a bio-acoustic fish fence (BAFF), at an angle across the lower lock approach so they could determine if it helps prevent the spread of the fish from the Cumberland River into Lake Barkley. The curtain of bubbles and the underwater lights and sounds may be noticeable to those navigating the lock, especially in lower water conditions. During the study period, which is now forecast to conclude in fall 2023, researchers turn the fence on for a week and off for a week and watch the movement of tagged silver carp through it, said Rob Simmonds, the U.S. Fish and Wildlife Service deputy fisheries program supervisor for aquatic invasive species.
