Northern Snakehead Fish

The Northern snakehead fish (Channa argus) is native to China, Russia and Korea. Snakeheads are highly invasive and have the potential to disrupt recreational and commercial fishing, harm native fish and wildlife, and impact our economy.  Northern snakeheads are top predators capable of growing to at least three feet long and surviving throughout the continental US in a variety of habitats. They feed voraciously and spawn multiple times each year.  When oxygen is insufficient to support most of our native fish, snakeheads can breathe air and they may survive for days out of water in damp conditions. Young fish can move across the ground to access water.  New York State prohibits possession, sale and live transport of snakehead fish (genus Channa and Parachanna) and their viable eggs. Importation and interstate transport of snakeheads is prohibited under federal Lacey Act  [from the NYS Dept. of Environmental Conservation].
