Description:

To facilitate population analyses, the following data and explanations of collection procedures on land since the 1911 Convention are summarized for the northern fur seal, Callorhinus ursinus, of the Pribilof Islands, Alaska: rookery-specific counts and estimates of numbers of pups born, live pups, and dead pups (1912-79); information on causes of pup mortality on land (1964-78); rookery-specific counts of adult males which are classified as idle, and breeding or harem bulls (1911-79); daily commercial kills of males (1918-79) and of females (1956-68) by area; and counts on the killing fields (St. Paul Island only) of seals entangled in fishing nets and other commercial debris in recent years (1967-79). The data and estimates are primarily from annual reports of the National Marine Mammal Laboratory and its predecessor organizations; a special effort was made to document the pup numbers because of their unique importance in population work. A brief historical review and a provisional interpretation of events since the mid-1950s are presented. This information is intended to implement the intent of the Congress in the Marine Mammal Protection Act of 1972. It will also be included in comprehensive data reports being prepared by the North Pacific Fur Seal Commission.
