When shell-boring marine worms were first documented in Olympia oysters in 2020, they raised an important question for restoration: were these parasites always part of the Salish Sea ecosystem, or were they accidentally introduced with Pacific oysters a century ago? That mystery sent researchers on an investigation thousands of years into the past.
Is a Newly Discovered Worm a Threat to Oysters in the Salish Sea?
Is a newly discovered shell-boring worm a threat to Olympia oysters—a species of concern and the only oyster species in the Salish Sea?
Dr. Chelsea Wood and her team at the University of Washington School of Aquatic and Fishery Sciences aims to answer that question. If so, this will be crucial information to modify the current restoration plan for Olympia Oysters (Ostrea lurida).
