Survival and growth performance of the japanese scallop Patinopecten yessoensis seeds produced in the upper tolerant temperature

The Japanese scallop (Patinopecten yessoensis), a cold-tolerant bivalve, is one of the key species cultured in suspension on the Gangwon coast of the East Sea (Sea of Japan). However, since the commencement of the scallop farming in early 1990s mass mortalities occurred most probably due to daily te...
