Mollusks Bivalvia

The bivalve mollusks include clams, oysters, mussels and scallops. The common oyster (also called flat native or European oyster) and the blue or common mussel are the most often processed molluscan shellfish. 

Oysters Ostreidae, e. g. the European oyster, Os-trea edulis) live in colonies along the sea coast or river banks, or are cultivated in ponds ( oys- 

The blue or common mussel Mytilus edulis) lives in shallow, sandy freshwater, while the sea mussel lives in ocean water or is cultivated in ponds or lakes. The shell, 7-15 cm long, is bluish black and the body meat is yellowish. The meat is rich in protein (16.8%) and also in vitamin A and the vitamin B-complex. The meat is eaten cooked, fried or marinated. The major mussel growing areas in Germany are the Kiel Bay and the East Friesian Islands. 

In addition to common mussel, numerous other mussels are eaten, mostly canned in vegetable oil, e. g.. Pacific Bay or Cape Cod scallops Pec-tinidae) and cockles Cardidae). 

Due to rapid spoilage, mussels are marketed hve or canned. They are eaten soon after being caught or after the can is opened, and are avoided in warm seasons. Moreover, they should originate from uncontaminated clear waters.

The largest number of species of mollusks are in the class Gastropoda, which includes snails with a coiled shell, and others lacking a shell. The next largest group are the bivalves (class Bivalvia), the chitons (class Am-phineura), and octopus and squid, (class Cephalopoda). The other classes of mollusks are the class Scaphopoda (consisting of a few species of small mollusks with a tapered, tubular shell) and the class Monoplacophora, a...
