Nope: it's a Natural Starin Muskie. The Potomac DOES have some stocked Tigers (the fingerlings came from PA), but they stopped stocking them with the emergence of Naturals. They ARE reproducing with fish of 30+ pounds being taken.

Due to the "whirling disease" stocking has stopped (hopefully temporarily) of fish from other states. Maryland traded Stirper fingerlings to PA hatcheries in exchange for the Tiger fingerlings.

Tigers were doing quite well. Hopefully, restocking river fingerlilngs will start a very good fishery here.

It is not known where the naturals came from with rumors of illegal stocking, etc. They started showing up a few years ago and are doing very well in the upper areas of the river.
