| 摘要： | Preliminary test results suggest a bio-acoustic fish fence (BAFF) installed at Barkley Dam in November 2019 is deterring the movement of Asian carp from the Cumberland River into Lake Barkley. Lyon County (Ky.) Judge-Executive Wade White announced in June that a report he received from U.S. Fish and Wildlife Service (USFWS) Midwest Fisheries Center Director Teresa D. Lewis, Ph.D., indicated promising results. Of the 254 silver carp tagged in the area during a study period from November 1, 2020, through February 13, 2021, 57 fish crossed the BAFF when it was turned off. Only four crossed it while the BAFF was on. Additionally, she said, the agency counted 3,181 times silver carp approached the BAFF when it was off but only 612 times when it was on, "suggesting possible avoidance behavior when the system is on." |
