Pennsylvania Fish and Boat Commission.

The Pennsylvania Fish and Boat Commission (PFBC) is urging anglers to report and dispose of any invasive Northern Snakehead fish that may be caught in the lower Susquehanna River. This 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. Anglers are reminded that possession, transport, and importation of a live snakehead is unlawful in both Pennsylvania and Maryland. Any of these invasive fish that are caught should be killed and disposed of properly or consumed. 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. For more information on Northern Snakeheads in Pennsylvania, including an identification guide, visit the PFBC snakehead resource page.
