Where did the Puget Sound green crabs come from? We’re still not sure.- Puget Sound Institute


It’s amazing how far afield the Columbia River affects environments. I’ve also heard it said by folks researching it that our Orca prefer (historically that is) the Columbia River (and Fraser River) Chinook and Chum. Maybe because of swimming longer distances make them more muscular? But again, research is the key to assumptions.

Genetic testing shows that invasive European green crabs in Puget Sound likely did not come from the Sooke Basin in British Columbia as previously thought. New findings on the crab’s origins were presented at the 2018 Salish Sea Ecosystem Conference in Seattle. Scientists are looking at a variety of potential sources.
