In the United States, the snakehead was first discovered in 1977 in Silverwood Lake in California. Historically live snakeheads were openly sold in the United States in pet shops and live fish markets. This fish is popular in the Asian food market and most introductions were likely released for this purpose. In 2002, the import and interstate transport of the northern snakehead was banned without a permit from the U.S. Fish and Wildlife Service.

Impacts

The northern snakehead will compete for food and habitat with native and sport fish.  Adults are voracious predators, feeding on other fish, crustaceans, frogs, reptiles, birds and small mammals. 

Status

Listed as a federal injurious wildlife species
