Upper Potomac Invaders

Type: Nontidal
Region: Western
Location: Upper Potomac

The invasive flathead catfish bite is on in the upper Potomac River! Recently discovered in the freshwater Potomac, these apex predators appear to have established themselves. Flathead catfish are extremely productive, creating high numbers of offspring each year. They grow fast, fight hard, and reach impressive sizes. Unfortunately, this biological invader consumes at various levels of the food chain in large quantities! They undoubtedly have serious potential to alter the natural ecology of the river, which may pose a serious threat to naturalized sport fish populations. Studies from other rivers suggest that these top predators negatively impact populations of both sunfish and crayfish; both of which serve as important prey for other popular game fish in the river. Anglers are encouraged to keep all that they catch and are reminded that there is no creel limit or minimum size restrictions for this species.

Pictured is Brett Poffenberger of Williamsport, MD who managed to land over 10 flatheads in a single weekend outing. He targeted woody-debris piles in areas of slow to moderate current. Brett enjoyed a fish fry with family and friends to compliment his Memorial Day picnic!
