The Secretary, on the basis of the best scientific evidence available and in consultation with the Marine Mammal Commission, shall prescribe such regulations with respect to the taking and importing of animals from each species of marine mammal (including regulations on the taking and importing of individuals within population stocks) as he deems necessary and appropriate to insure that such taking will not be to the disadvantage of those species and population stocks and will be consistent with the purposes and policies set forth in section 1361 of this title.
Any regulation prescribed pursuant to this section shall be periodically reviewed, and may be modified from time to time in such manner as the Secretary deems consistent with and necessary to carry out the purposes of this chapter.
Within six months after the effective date of this chapter and every twelve months thereafter, the Secretary shall report to the public through publication in the Federal Register and to the Congress on the current status of all marine mammal species and population stocks subject to the provisions of this chapter. His report shall describe those actions taken and those measures believed necessary, including where appropriate, the issuance of permits pursuant to this subchapter to assure the well-being of such marine mammals.
