What is the sea lion population?

Answer 1

The Northern Sea Lion is also commonly named the Steller Sea Lion.Mate (1982) estimated the California population at 5,000-7,000. He estimated the world population to be between 219,914 and 225,444. According to Trites and Larkin (1996) the Alaska and Aleutians population increased from 250,000 in the 1950s to 282,000 in the mid-70s. Since 1980, this population has declined with 5% per year to about 76,000 animals in 1992. Since 1989, the population decline seems to have stopped in the eastern Aleutians and the western Gulf of Alaska.

California sea lionMate (1979) reports a total population for Zalophus californianus californianus of around 50,000, which could be increasing. Mate (1982) estimates the total population at 75,000 to 100,000 and calls it a conservative estimate. The Galapagos sea lion, Zalophus californianus wollabaeki, numbers about 20,000. The Japanese sea lion, Zalophus californianus japonicus, is probably extinct.
