Diets can be estimated from an analysis of scats through both hard-part (bones) identification and genetic DNA analysis, as well as from biochemical analysis of blubber and skin samples obtained through biopsying of live animals. This survey will collect biopsies and scats from Harbour Seals, Steller Sea Lions and California Sea Lions on a monthly basis from spring through fall at key locations and along salmon migratory pathways. The goal is to estimate competition between pinnipeds and Resident Killer Whales for salmon prey. |
