Description:

Tbe Pribilof Island population of nortbern fur seals, Callorhinus ursinus, feeds on a variety of prey throughout its subarctic range from California to the Bering Sea. A total of 53 species of fish and 10 species of squid has been identified from the stomachs of fur seals taken during 1958-74. Some fur seal prey species are commercially fished while others are not of commercial importance but are important forage food for many other predators including other marine mammals, seabirds, and fishes. The season and location are important considerations. as are the migratory characteristics of forage species, when studying the diet of fur seals in the eastern Pacific. Evidence suggests that fur seals are opportunistic feeders preying on the most available species throughout their range.
