Notes on the Food of Fur Seal, Sea-Lion and Harbor Porpoise
Wilke F and Kenyon KW. 1952. Notes on the Food of Fur Seal, Sea-Lion and Harbor Porpoise. The Journal of Wildlife Management. 16(3):396-397
Aside from its interest to naturalists, the food of marine mammals is of direct concern to the fishing industry and conservation agencies. Our knowledge of the food of even such a commercially important mammal as the northern fur seal (Callorhinus ursinus) is surprisingly incomplete. Almost no studies have been made of their feeding habits on the vast wintering grounds off California, Oregon, and southern Washington. Despite widespread condemnation of the northern sea-lion (Eumelopias jubata) by fishermen, its food has not yet been accurately determined. Imler and Sarber, who made the most extensive investigation in Alaska, examined only 15 stomachs containing food. The following notes will add a few facts to the compilation of a geographically and seasonally complete record of the food of three common marine mammals.
