Abstract. The northern snakehead (Channa argus) is a large piscivorous fish that is invasive in eastern Europe and has recently been introduced in North America.n the winter (NovemberâApril), these fish moved to deeper water (~135 cm) with warmer temperatures, but habitat selection was weak at both scales. Northern snakeheads returned to shallower water (~95 cm) in the prespawn season (AprilâJune) and used milfoil and other cover.
Northern snakehead fish are voracious eaters that prey on fish, crustaceans, frogs, insects, small reptiles, birds, and mammals, with significant impacts to food chains and ecosystems. Adults may attack humans who approach young.
