Regional Impacts
Economic Impact | Fisheries | |
Oyster culture racks, ropes, and shells (of Crassostrea gigas, Pacific Oyster) in Bahia San Quintin, Baja California, Mexico were badly fouled by tunicates, beginning in 2002. Microcosmus squamiger was a major organism in this fouling (Rodriquez and Ibarra-Obando 2008). | ||
Ecological Impact | Competition | |
Microcosmus squamiger now greatly outnumbers Styela canopus, an earlier invader, in San Diego Bay. It forms single-species patches at some locations, suggestive of competition (Lambert and Lambert 2003). | ||
