Researchers emphasize the heightened urgency to save and restore the river's population. A Penn State research team, in collaboration with the Pennsylvania Fish and Boat Commission, has embarked on a mission to save a unique darter from the lower Susquehanna River. Their findings revealed that this

To reach their conclusion that the Chesapeake logperch, Percina bimaculata, is one of a kind — recently published in— the researchers collected thousands of specimens of logperch using seines, electrofishing units, and electrified benthic trawls from the Allegheny River, from tributaries of Lake Erie and from the lower Susquehanna River.

In Maryland, the researchers collected darters from just below Conowingo Dam and in the Susquehanna Flats at the river’s mouth in the Chesapeake Bay. The fish has been a victim of past pollution, Stauffer pointed out, but now is threatened by predation by voracious invasive fishes, including the northern snakehead, flathead catfish and blue catfish that are colonizing the lower Susquehanna. The numbers of the Chesapeake logperch have dwindled significantly in the river and a few of its tributaries.
Why go to all this trouble to save this unimpressive little fish? Stauffer admitted he had asked himself that question. Because the Chesapeake logperch has no commercial value and it is not of recreational importance, a conventional cost-benefit analysis on losing the fish cannot be performed, he conceded.
