Northern Snakehead Channa argus (Cantor, 1842)Non-native  -  Invasive  

Status:

"In 2002, a reproducing population of northern snakeheads was discovered in a pond in Crofton, Maryland. The snakeheads were exterminated and subsequently assigned injurious wildlife status under the Federal Lacey Act which prohibits import and interstate transport. A mid-Atlantic Aquatic Nuisance Species council was formed and a management plan for northern snakeheads was drafted. Despite intense media and political attention, increased awareness did not serve to prevent further introductions. In 2004, northern snakeheads were found in the Potomac River near the nation's capitol and have since established a reproducing population." (MD DNR) The species continues to expand into other Bay tributaries.
