Monitoring plan for the eastern North Pacific population of gray whale, which is proposed for delisting

The population status of northern fur seals Callorhinus ursinus ) on st. Paul Island has been monitored annually since 1911. Annual reports of research on the population status of northern fur seals on all U. s. breeding rookeries (including st. Paul Island) and throughout their pelagic North Pacific and Bering Sea range (Fig. 1) have been published since 1940 excluding, a 3-year break during World War II. This series of publications, first produced by the Marine Mammal Biological Laboratory (later to become the National Marine Mammal Laboratory) represents one of the longest-running documentations of life history patterns and dynamics of a wild animal population. From 1911 to 1984, northern fur seal research was carried out by Canada, Japan, the Soviet Union, and the United States under a convention for the conservation of North Pacific fur seals. Since 1984, studies have been conducted independently, but cooperatively by former member nations.

Scientists from the National Marine Mammal Laboratory have published reports of annual studies of northern fur seals from the Pribilof Islands since 1958, and from San Miguel Island off Southern California since 1968. This document presents the results of research conducted in 1992.

Observations of the Prince William Sound driftnet fishery May - October 1991

Discussion of the Cook Inlet beluga whale stock's distribution, population size, food habits, reproduction, subsistence harvest, and recommendations for monitoring their status.

This report summarizes northern fur seal (Callorhinus ursinus) research conducted by scientists from the National Marine Mammal Laboratory in 1991. Research was conducted on St. George Island and St. Paul Island of the Pribilof Island group in the eastern Bering Sea, and on San Miguel Island and Castle Rockin Southern California.

Final report of observer program methods and results in Alaska.

This report summarizes the research carried out by scientists from the National Marine Mammal Laboratory at four northern fur seal breeding sites during 1990.

The National Marine Mammal Laboratory (NMML) is responsible for collecting biological and management data on the northern fur seal (Callorhinus ursinus). This responsibility is mandated under the Fur Seal Act and the Marine Mammal Protection Act, in absence of the Fur Seal Convention which expired in 1984.
