	note = {Colonial tunicates are concerning to shellfish growers. They foul gear, smother shellfish, and interfere with the settlement of shellfish larvae.  The invasive colonial tunicate Didemnium vesillum, colorfully called {\textquotedblleft}sea vomit,{\textquotedblright} has shown up at two sites in Oregon, at Charleston Marina in Coos Bay and at Umpqua Aquaculture in Winchester Bay.  This species is considered to be one of the 100 most dangerous invasive species in Oregon.  In this article, the authors describe five years of monitoring the Winchester Bay colony, from 2011-2016.  Over that time, the size of the colony declined. The authors warn, however, that because this species is extremely adaptable, it can propagate vigorously, and stress that any populations should be regularly monitored.},
