ABSTRACT- To achieve sustainable fishery, it is indispensable to incorporate environmental measures into fishery production process in addition to a resource and economic viewpoint. Life Cycle Assessment (LCA) is an important and useful tool to evaluate the environmental effects and potential impacts associated with a product and a service throughout its life span. Although it has been widely used in many industry sectors, no report has been found in the fishery industry based on LCA perspective. In this research, we quantitatively calculated the environmental burden of the entire squid and scallop fishing systems in Japan and assessed the environmental impacts using LCA. Squid and scallop were chosen for this case study because they are important fishery products for the Japanese food supply. Moreover, we suggested the evaluation procedure, while applying LCA to the fishery. As to squid related fishery, squid jigging fishery exhibited the largest environmentally burden, followed by off-shore trawl fishery, and large scale set-net fishery. The results suggested the largest value of the squid jigging fishery was mainly due to the use of fuel oil by fish gathering lamps. As to the scallop cultivation industry, on the other hand, the value indicated the ground sowing method was superior to the hanging method. We demonstrated that LCA was applicable to fishery, and this new methodology was to be useful toward the improvement of the environmental aspects of fishery.
