negotiations as soon as possible with all foreign governments which are engaged in, or which have persons or companies engaged in, commercial fishing operations which are found by the Secretary to be unduly harmful to any species or population stock of marine mammal, for the purpose of entering into bilateral and multilateral treaties with such countries to protect marine mammals, with the Secretary of State to prepare a draft agenda relating to this matter for discussion at appropriate international meetings and forums;

discussions with foreign governments whose vessels harvest yellowfin tuna with purse seines in the eastern tropical Pacific Ocean, for the purpose of concluding, through the Inter-American Tropical Tuna Commission or such other bilateral or multilateral institutions as may be appropriate, international arrangements for the conservation of marine mammals taken incidentally in the course of harvesting such tuna, which should include provisions for (i) cooperative research into alternative methods of locating and catching yellowfin tuna which do not involve the taking of marine mammals, (ii) cooperative research on the status of affected marine mammal population stocks, (iii) reliable monitoring of the number, rate, and species of marine mammals taken by vessels of harvesting nations, (iv) limitations on incidental take levels based upon the best scientific information available, and (v) the use of the best marine mammal safety techniques and equipment that are economically and technologically practicable to reduce the incidental kill and serious injury of marine mammals to insignificant levels approaching a zero mortality and serious injury rate;

discussions with those countries participating, or likely to participate, in the International Dolphin Conservation Program, for the purpose of identifying sources of funds needed for research and other measures promoting effective protection of dolphins, other marine species, and the marine ecosystem;

in consultation with the Marine Mammal Commission established by section 1401 of this title, undertake a study of the North Pacific fur seals to determine whether herds of such seals subject to the jurisdiction of the United States are presently at their optimum sustainable population and what population trends are evident; and

in consultation with the Secretary of State, promptly undertake a comprehensive study of the provisions of this chapter, as they relate to North Pacific fur seals, and the provisions of the North Pacific Fur Seal Convention signed on February 9, 1957, as extended (hereafter referred to in this subsection as the “Convention”), to determine what modifications, if any, should be made to the provisions of the Convention, or of this chapter, or both, to make the Convention and this chapter consistent with each other.

as a result of the study required under paragraph (1)(A) of this subsection, that the North Pacific fur seal herds are below their optimum sustainable population and are not trending upward toward such level, or have reached their optimum sustainable population but are commencing a downward trend, and believes the herds to be in danger of depletion; or

as a result of the study required under paragraph (1)(B) of this subsection, that modifications of the Convention are desirable to make it and this chapter consistent;
