The regulations contained in 50 CFR part 16 implement the Lacey Act
(18 U.S.C. 42) as amended. Under the terms of that law, the Secretary
of the Interior is authorized to prohibit by regulation certain
activities involving wild mammals, wild birds, fish (including mollusks
and crustaceans), amphibians, reptiles, and the offspring or eggs of
any of the foregoing that are injurious to human beings, to the
interests of agriculture, horticulture, or forestry, or to the wildlife
or wildlife resources of the United States. The lists of injurious
wildlife species are at 50 CFR 16.11 to 16.15. By adding snakehead
fishes to the list of injurious wildlife, their importation into, and
transportation between, States, the District of Columbia, the
Commonwealth of Puerto Rico, or any territory or possession of the
United States by any means whatsoever is prohibited, except by permit
for zoological, educational, medical, or scientific purposes (in
accordance with permit regulations at 50 CFR 16.22), or by Federal
agencies without a permit solely for their own use, upon filing a
written declaration with the District Director of Customs and the U.S.
Fish and Wildlife Service Inspector at the port of entry. No live
snakehead fish, progeny thereof, or viable eggs imported or transported
under a permit may be sold, donated, traded, loaned, or transferred to
any other person or institution unless such person or institution has a
permit issued by the Director of the U.S. Fish and Wildlife Service.
The interstate transportation of any live snakehead fish or viable eggs
currently held in the United States for any purpose is prohibited
without a permit.
