The Maryland Department of Natural Resources (DNR) recently released survey information from the 2021 spring Conowingo Dam fish lift operations.
A total of 6,354 adult American shad were successfully transported alive from the fish lift to Columbia, Pa. so they could spawn.
During the spring 2021 shad season, 952 northern snakeheads and 1,098 flathead catfish were removed from the fish lift. The invasive fish were processed and donated to Maryland food banks.
Sorting and removal of invasive northern snakeheads and flathead catfish will be a continuing process in the future, according to DNR.
In recent years, northern snakeheads, flathead catfish, blue catfish, and other invasive species have spread throughout much of the Chesapeake Bay watershed.
