Alien Invaders: invasive tunicates and shellfish aquaculture


Several years ago, Washington State began tracking and eradicating invasive tunicates. Teams of scuba divers used ice scrapers and even blow- torches to remove tunicates at low tide, and divers removed a ton of them from just two marinas. SeaDoc supported Jeff Cordell and colleagues at the University of Washington to collect and analyze data on the impact of these tunicate species. Refreshingly, the research found little evidence that the three tunicate species of most concern are damaging our local ecosystem and our valuable shellfish industry. That’s great news for our local shellfish.
