Biology
Oysters belong to the commercially important group of bivalve molluscs which also includes mussels, clams and cockles. The Pacific oyster, now widely distributed, originated in northeastern Asia. Pacific oysters, as with many oyster species, develop first as males, spawn, and then later develop into females. Spawning occurs in the summer.
