Description

Abstract: This report summarizes the fourth year of research on pinniped predation on salmonids at Alsea Bay, Oregon, conducted by the Oregon Department of Fish and Wildlife’s Marine Mammal Program. Background and motivation for this research is described in Riemer et al. (2001). Our objective in 2000 was to continue our assessment of whether pinnipeds posed a threat to the recovery of coho salmon (Oncorhyn-chus kisutch) in the Alsea basin. We carried out this assessment using three approaches: (1) surface feeding observations to estimate total predation; (2) marking and resighting of Pacific harbor seals (Phoca vitulina richardsi) to characterize movements, habitat use and foraging behavior; and (3) collection of seal fecal (scat) samples to describe diet.
