We examined what we should consider for design of purse seine vessel in Japan by comparing the characteristics of “large and medium- scale purse seine fishery”in Japan with “large scale purse seine fishery”in Norway. We concluded that there are three points which we should consider. At first, we should determine the appropriate level of the fishing capacities of the large and medium-scale purse seine fisheries in Japan based on the capacities of processing plants on land. The insufficiency of processing capacities often causes price collapse of the landing. Next, the transport ship is necessary in the operations of large and medium- scale purse seine fishery in Japan, because the use of transport ships largely contributes to the stability of landing price. Finally, the profitability of large and medium- scale purse seine fishery in Japan tends to be less than in Norway, so the design of the purse seine vessels in Japan should be determined based on this low profitability.
