Laboratory analysis of diet of Pacific harbor seals at Umpqua River, Oregon and Columbia River, Oregon/Washington conducted from 1994-06-23 to 2005-09-03 (NCEI Accession 0139413)

Data provided by  National Oceanic and Atmospheric Administration

From 1994 to 2005, The National Marine Mammal Laboratories' California Current Ecosystem Program (AFSC/NOAA) collected fecal samples at the Umpqua River, Oregon and Columbia River, Oregon/Washington to examine the diet of Pacific harbor seals (Phoca vitulina). Scats were collected at various sites on the Umpqua River and at Desdemona sand spit on the Columbia River. Apart from describing the diet of Pacific harbor seals in these regions, of special interest was to determine the level of predation by these seals on endangered or threatened salmonids (e.g., cutthroat trout; Oncorhynchus clarkii).
