On May 19, 1992, President George Bush transmitted to the Senate for advice and consent to ratification the Convention for the Conservation of Anadromous Stocks in the North Pacific Ocean, with Annex, signed at Moscow on February 11, 1992. An accompanying report by Secretary of State James A. Baker III, dated May 14, 1992, stated, in major part: The Convention has as its centerpiece a prohibition on high seas fishing for Pacific salmon, which will protect valuable migrating U.S.-origin salmonids. It also establishes a new international organization to promote the conservation of anadromous stocks (primarily Pacific salmon) throughout their migratory range in the high seas area of the North Pacific Ocean and its adjacent seas, as well as ecologically related species that interact with these resources, including various marine mammals, seabirds, and non-anadromous fish species. The new organization, which is to be known as the North Pacific Anadromous Fish Commission, will also serve as a needed venue for consultation and coordination of high seas fishery enforcement activities by the contracting parties.

The diets of Laysan (Diomedea immutabilis) and black-footed albatrosses (D. nigripes) killed in squid and large-mesh drift nets in the transitional zone of the North Pacific Ocean were investigated by examining the contents of the digestive tracts and determining δ13C and δ15N values in breast-muscle tissue. The results show that (i) the combined prey of the two species of albatross consists of over 46 species of marine organisms including coelenterates, arthropods, mollusks, fish, and marine mammals; (ii) both species supplement their traditional diets with food made available by commercial fishing operations (e.g., net-caught squid and offal); (iii) while obtained from drift nets, diets of nonbreeding Laysan and black-footed albatrosses are dominated by neon flying squid (Ommastrephes bartrami); (iv) in the absence of drift-net-related food, Laysan albatrosses feed most heavily on fish and black-footed albatrosses feed most heavily on squid; and (v) based on δ15N values, nonbreeding adult Laysan albatrosses from the transitional zone of the North Pacific Ocean and Laysan albatross nestlings fed by adults from Midway Island in the subtropical Pacific feed at one trophic level and one-third of a trophic level lower than black-footed albatrosses, respectively.
