European Oyster (Ostrea edulis) populations in Casco Bay were considered sufficient to support limited fisheries (Heinig and Tarbox 1985; Hidu and Lavoie 1991). Aquaculture of this oyster has had mixed results, because of disease (Bonamia ostreae) and other culture problems. Aquaculture research in Maine is continuing, and there is a demand for this oyster because of its flavor (Morse 2011). | ||
