In some places, yes, but under several constraints. Specifically, importation of live snakeheads and their interstate transport is prohibited. Many states prohibit possession of snakeheads, and several of those states have done so for decades.
Most snakeheads will avoid contact with humans. However, when guarding their eggs or young, they can become aggressive if approached.
Dead snakeheads--on ice or frozen--can be imported for food purposes to any state except those where importation or possession of dead snakeheads is illegal.
Although claims of their mobility have been greatly exaggerated, several species of snakeheads are able to wriggle overland from one body of water to another, particularly if the ground is wet.
Northern snakeheads were purposefully introduced and established into Japan in the early 1900s.
Prior to being added to the list of injurious wildlife under the Lacey Act in October 2002, which banned import and interstate transport without a permit from the U.S.
A mature northern snakehead female can carry as many as 50,000 eggs, although some will not develop and others will be eaten by insects and small fishes following fertilization. Depending on water temperature, eggs can hatch in about 24-48 hours.
Snakeheads are airbreathing freshwater fishes that are not native to North America. In scientific terms, snakeheads are divided into two distinct genera:* Channa (snakeheads of Asia, Malaysia, and Indonesia); and
* They are very predatory and could alter conditions in our aquatic ecosystems.* They are airbreathers and several species are capable of overland migration during some part of their life history.
During all life stages, snakeheads compete with native species for food and habitat. As juveniles, they eat zooplankton, insect larvae, small crustaceans, and the young of other fishes.
