Better check again. The federal Lacey Act put the breaks on snakeheads throughout the US and its' territories. They're illegal to acquire, sell, transport over state lines, or own without a permit. There are NO permits for private owners. Permits are issued to institutions only. Here's the summary of the Lacey Act:
The Lacey Act prohibits the importation, transportation, and acquisition of wildlife species deemed to be "injurious" by the U.S. Fish and Wildlife Service. The following fish and invertebrate species are considered to be injurious under the Act:

And as far as permits are concerned:
SUMMARY: The U.S. Fish and Wildlife Service adds all species of
snakehead fishes in the Channidae family to the list of injurious fish,
mollusks, and crustaceans. By this action, the Service prohibits the
importation into or transportation between the continental United
States, the District of Columbia, Hawaii, the Commonwealth of Puerto
Rico, or any territory or possession of the United States. The best
available information indicates that this action is necessary to
protect wildlife and wildlife resources from the purposeful or
accidental introduction and subsequent establishment of snakehead
populations in ecosystems of the United States. Live snakehead fishes
or viable eggs can be imported only by permit for scientific, medical,
educational, or zoological purposes, or without a permit by Federal
agencies solely for their own use; permits will also be required for
the interstate transportation of live snakeheads or viable eggs
currently held in the United States, for scientific, medical,
educational, or zoological purposes. This final rule becomes effective
immediately upon publication.
DATES: This rule is effective October 4, 2002.
