This 33 second underwater video was taken during phase I of an invasive sea squirt cleanup effort at an oyster farm in Sitka. Commercial Fisheries Division divers used burlap bags to enclose oyster nets that had been encased by the invasive colonial sea squirt, Didemnum vexillum. In order to reduce the chance of spreading the sea squirt during the cleanup, bags were used to capture any fragments of the tunicate that could break off, float in the water column, and then settle, starting new colonies. After the nets were bagged they were removed from the water and disposed at a site far from the marine environment.
