Northern Snakeheads in Pennsylvania

The northern snakehead is one of the most notorious aquatic invasive species found in Pennsylvania. This slender fish is found in several rivers and impoundments in the state

In May, 2020, the Pennsylvania Fish and Boat Commission (PFBC) urged anglers to report and dispose of any invasive Northern Snakehead fish that may be caught in the lower Susquehanna River.

The advisory follows the documented movement of 21 Northern Snakeheads past the Conowingo Dam into the Conowingo Pool, a 14-mile-long section of the Susquehanna River located between the Conowingo Dam in Maryland and the Holtwood Dam in Pennsylvania.

Fisheries management of the Conowingo Pool is shared between the PFBC and Maryland Department of Natural Resources (MD DNR).

In late March, operators of the fish passage systems used at the Conowingo, Holtwood, and Safe Harbor dams to assist migrating American Shad during their spring spawning runs indicated that due to restrictions associated with COVID-19, fish passage operations had been delayed from the original start date of April 1.

Over the course of four days, lift operators observed 35 northern snakeheads within the east fish lift; 14 of the invasive fish were able to be netted and removed, while another 21 entered the Conowingo Pool.

Due to the concern over increased invasive species passage and the lateness of the season for successful American Shad passage, the Susquehanna River Anadromous Fish Restoration Cooperative (SRAFRC) recommended that fish passage operations be immediately ceased to prevent further passage of snakeheads.

Fish passage operations at the Holtwood and Safe Harbor dams upriver were also ceased immediately, although no snakeheads were observed at either location.

Northern Snakeheads were discovered in the mid-Atlantic region in 2002 when a pair were discovered in a Maryland pond.

Snakeheads were confirmed in Pennsylvania in July 2004 in Meadow Lake, Philadelphia County, and are present in the connecting lower Schuylkill and Delaware rivers.

In summer 2018, anglers began catching snakeheads in Octoraro Creek in Lancaster County, a tributary that enters the Susquehanna River below the Conowingo Dam; however, snakeheads are not known to occur in the upper Octoraro Creek basin above the dam at Pine Grove.

In September 2019, an angler reported catching of a single snakehead in the Monongahela River near Braddock, PA, and the specimen was verified by PFBC biologists.

Anglers are reminded that possession, transport, and importation of a live snakehead is unlawful in both Pennsylvania and Maryland.

Anglers who suspect they have caught a snakehead are encouraged to NOT release it, and report it to the PFBC at (610) 847-2442 or by sending an email to tgrabowski@pa.gov.
