September 23, 2021 — The long-running effort to get American shad back to their historic spawning grounds this year enlisted a tool that had been abandoned two decades ago: trucks.
With operation of the multi-million dollar fish lifts halted at Conowingo Dam, biologists resorted to capturing shad below the dam and trucking them upstream before releasing the fish back into the Susquehanna River to continue their spawning migration.
By the time the trucks stopped running on June 5, they hauled more than 6,300 shad upstream. That’s a fraction of the number that swam upriver during historic shad runs, but it’s the most that got past the first three dams on the river in more than a decade.
And it wouldn’t have happened without the trucks. Fish lifts at the 94-foot-high dam have not operated for two years because of concerns that invasive species such as northern snakeheads and blue catfish were moving upstream through the fish lifts, too.
“From a shad perspective, we feel like in the short term it is best to get as many to the spawning grounds as we can,” said Sheila Eyler, who coordinates fish restoration efforts on the Susquehanna for the U.S. Fish and Wildlife Service.
American shad definitely needed the helping hand.
