The Chesapeake logperch (Percina bimaculata) is a small species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches.

[3] The Chesapeake logperch are freshwater, benthopelagic fish that live near gravel runs and riffles in clear, medium-sized rivers.

[2] Currently, the Chesapeake logperch is classified as threatened by the states of Pennsylvania and Maryland due to its limited global distribution within only a small portion of its historical range.

As part of the project, adult brood stock were collected from several tributaries of the Susquehanna River and approximately 1,500 juvenile fish were cultured at laboratories at Conservation Fisheries, Inc. in Knoxville, Tennessee, and under the direction of Distinguished Professor of Ichthyology, Jay Stauffer, Jr., PhD at Penn State University in State College, Pennsylvania.

On September 26, 2019, the PFBC along with project partners including the USFWS, Penn State University, Susquehanna River Basin Commission, Pennsylvania Biological Survey, Maryland Department of Natural Resources and Conservation Fisheries, Inc. successfully released 1,500 healthy Chesapeake Logperch juveniles into Chiques Creek, near Columbia, Lancaster County, PA. Future research will include surveys of the area to determine the survival of the introduced fish and gauge natural reproduction and recruitment.
