Description
Summary:	Stock size, distribution, size and age composition, and growth of Japanese scallops,Mizuhopecten yessoensis, were studied at eight sites in Possjet Bay, Sea of Japan, Russia. At seven sites, most of the scallops were cultured animals (seeded as one-year-olds in 1986–1989). At the eighth site, only native (i.e. naturally settled) scallops were present. Cultured scallops had an irregular strip-like distribution at all locations. Maximum growth of scallops occurred in the northwestern part of Reid Pallada Bight. Only at Temp Bight did both native and the majority of cultured scallops attain the harvest size of 100 mm shell height at age 3 years. At all other sites in Possjet Bay, cultured scallops reached harvest size at an age of 4 years.
