Shallow Water Nearshore Fish Assemblages around Steller Sea Lion Haulouts near Kodiak, Alaska
نویسندگان
چکیده
What Scientists Did Nearshore fishes around haulouts are potential prey for Steller sea lions, especially pups, as they learn to forage and supplement their milk diets during weaning. Scientists conducted spring, summer, and winter scientific diving surveys around two Steller sea lion haulouts and two control sites on Kodiak Island to determine the abundance and composition of forage fishes. Concurrent habitat surveys were used to quantify substrate, macroalga, and benthic invertebrate cover.

Seasonal Differences in Prey Availability Around a Steller Sea Lion Haulout and Rookery in the Gulf of Alaska
Abundance and distribution of fish biomass were surveyed around a Steller sea lion (Eumetopias jubatus) haulout (nonbreeding) and rookery (breeding) site in the Gulf of Alaska to test the hypothesis that seasonal occupation of either site was related to the availability of prey. The haulout and rookery are located 30 nmi (55.56 km) apart at Long Island and Marmot Island in the Central Gulf of A...
متن کاملA Longitudinal Study of Steller Sea Lion Natality Rates in the Gulf of Alaska with Comparisons to Census Data
Steller sea lion (Eumetopias jubatus) numbers in the Western Distinct Population Segment are beginning to recover following the dramatic decline that began in the 1970s and ended around the turn of the century. Low female reproductive rates (natality) may have contributed to the decline and remain an issue of concern for this population. During the 2000s we found high natality among Steller sea...
متن کاملSupplemental Environmental Impact Statement
The Gulf of Alaska and Bering Sea Aleutian Islands groundfish fisheries have been managed under fishery management plans since 1978 and 1981, respectively. The range of the Steller sea lion overlaps the waters where the fisheries are conducted. Under the Endangered Species Act, Steller sea lion west of Cape Suckling, Alaska, are listed as endangered; east of Cape Suckling they are listed as thr...
متن کاملAn Accounting of the Sources of Steller Sea Lion Mortality
During 1991-2000, the western stock of Steller sea lions (Eumetopias jubatus) declined at 5.2% (SE = 0.3%) per year. The population declined at statistically significant rates (P < 0.10) in all regions except the eastern Aleutian Islands. The greatest rates of declines occurred in the eastern and central Gulf of Alaska and the western Aleutian Islands (all greater than 8.6% per year). Using a p...
متن کاملComparisons of Walleye Pollock, Theragra chalcogramma, Harvest to Steller Sea Lion, Eumetopias jubatus, Abundance in the Bering Sea and Gulf of Alaska
Steller sea lion, Eumetipias jubatus, counts made on rookeries in the Gulf of Alaska, Aleutian Islands, and the Bering Sea from 1976 to 1991 were compared to annual estimates of walleye pollock, Theragra Chalcogramma, harvest to examine possible relationships between Steller sea lion abundance and commercial pollock fishing. Comparisons were made between Steller sea lion counts and pollock fish...
