AFSC/NMML/CCEP: Sampling locations for harbor seal genetics in Washington and British Columbia

Using skin samples from 777 unweaned pups collected in 9 different regions in WA state and British Columbia (WA Coastal Estuaries, WA North Coast, British Columbia, Boundary Bay, San Juan Islands, Smith/Minor Islands, Dungeness Spit, Hood Canal, South Puget Sound), the California Current Ecosystem Program at the Marine Mammal Laboratory/AFSC tested levels of genetic variation using mtDNA and 9 microsatellite loci. For both mtDNA and microsatellites we found the same four groupings. Previously, harbor seals were managed as two stocks: coastal and Inland waters. The data indicated that the harbor seals should be managed as four stocks: one on the Coast and three stocks in the Inland Waters. An additional 92 skin samples were collected opportunistically from non-pups. They have not yet been analyzed.
