Sea Squirt Invades BLM Submerged Lands in Southeast Alaska

An invasive marine invertebrate known as “marine vomit,” that can smother native species has been found within Whiting Harbor in Sitka. This non-native carpet sea squirt, Didemnum vexillum, (D. vex) is thought to be native to Japan. It was first detected in Whiting Harbor in 2010 as a result of a citizen-science-marine invasive species bioblitz. Tammy Davis, Alaska Department of Fish and Game (ADF&G), invasive species program lead, was concerned along with other stakeholders including local Sitkans and those who work in the marine invasive species world, about the discovery and potential growth and spread of D. vex in Whiting Harbor.
