The annual yield of cultivated scallop Patinopecten yessoensis, has exceeded 80 thousand tons in recent years at the Oshima area in Hokkaido. But because of the dampened price of the product, the scallop cultivation fishery faces a hard ship. Addressing this, this paper presents a cooperative system that consists of setting a targeted annual yield and allocating it to fisheries. First, We present the two systems for setting targeted yield, then we propose allocation of the target yield to fishery cooperative associations, using the contested garment (CG) principle, one of the allocation methods under the cooperative scheme. The allocation result based on the CG principle is appropriate for both large-scale and small-scale fishery cooperative associations depending on the targeted yield.
