The Puzzle Of The Disappearing Steller Sea Lions

Since 1980, the world population of Steller sea lions has dropped from more than 300,000 animals to less than 100,000 and continues to decline. The North Pacific Universities Marine Mammal Research Consortium, made up of four participating institutions and the Vancouver Aquarium, was formed to undertake a long-term research program on the relationships between fisheries and marine mammals in the North Pacific Ocean. Steller sea lions at the Aquarium are directly participating in a comprehensive research study for this project.
