Alaska Northern Fur Seal Stomach Contents from Pelagic Collections 1981-1985

This data set contains food habits determined from stomachs of northern fur seals collected from pelagic waters during 1981-1985. Prey items were identified using hard parts including bones, otoliths, and cephalopod beaks.

The primary purpose of this data set is to identify species and sizes of northern fur seal prey in Alaska.

This dataset should be cited as coming from Sinclair, E. 1989. Feeding habits of northern fur seals (Callorhinus ursinus) in the Eastern Bering Sea. Available at NMFS Alaska Fisheries Science Center Access Dataserver:
