    • AFSC/NMML/CCEP: Food habits of California sea lions in Washington, 1986 - 1999

    Metadata Updated: June 1, 2025

    From 1986 to 1999, The National Marine Mammal Laboratories' California Current Ecosystem Program (AFSC/NOAA) collected fecal samples and stomachs of male California sea lions from Washington. Scat samples were collected primarily from haulout sites in Puget Sound and a few were collected along the northern-outer Washington coast. Stomach content samples were collected from dead/stranded California sea lions throughout Washington. The data contains prey identifications and analyses of samples including prey species composition, frequency of occurrence, and size of prey.

    Lineage Samples were collected at California sea lion haulout sites in Washington and from stomach from dead sea lions throughout Washington. Fecal and stomach samples were cleaned. Prey hard parts were separated using nested sieves, and subsequently identified. Sizes of prey were determined from measurements of fish otoliths and cephalopod beaks using calipers or ocular micrometer. Measurements were used to estimate prey size from published regression equations. Data were entered into a database. Data analyses were performed to address research questions about California sea lion diet.
