This chapter discusses the biology of scallop industry in Japan. The scallop industry supports Japan's coastal fisheries and cultures with an annual increase in economic activity in shellfish producing communities. The scallop is found to be the most valuable, with the oyster coming second; the oyster landing being 37,950 million yen in value and 221,252 mt in weight. The pearl oyster produces a gem; however, it is separated from the shellfish fisheries statistics. “Yoshoku”, possessive culture in the demarcated sea, is held by the demarcated fishery, its produce contributing to the stabilization of the supply of good quality seafood. “Yoshoku” areas are separated by caging or fencing from the common sea or culture facilities that may be set up in these areas. Scallops in hanging culture grow more rapidly than in sowing culture. All scallop seed are produced from a natural spat collection. Many animals prey on or compete with scallops, starfishes, sea urchins, octopuses, crabs, and fishes.
