In June 2010, researchers discovered Didemnum vexillum — also known as “rock vomit” — in Whiting Harbor near Sitka. This species, which can cover large areas of the seafloor, is an aggressive invader and a potential threat to shellfish farms, groundfish fisheries, fish spawning and other resources. The council is also concerned about the European green crab which can potentially travel in the ballast water of oil tankers and be released into Prince William Sound.
