UW Conservation Canine Tucker is in the news again for his fabulous work helping Puget Sound orcas! Tucker assisted Biology professor Sam Wasser and graduate student Katherine Ayres identify the main culprit stressing the whales, whose population has diminished in recent years. It turns out drastic shortages of Chinook salmon, the orcas main food supply, is much worse for the whales than commotion caused by whale watching boats. That's good news for tour boats, but now a plan is needed to make sure these iconic species get enough fish to eat! Click here to read all the details.
