The investigation into the energy consumption in some Japanese fisheries and the measures to reduce CO2 emissions
Japan’s fish production volume in 2008 was 5.59million tons, it accounted for 4% of world’s production and consisted of catch (4.40million tons) and aquaculture (1.19 million tons). For the far sea fishery, its’ fishing grounds are in domestic and foreign countries’ exclusive economic zone and international waters, since the total production volume of this fishery has been declining, offshore and coastal fishery have become mainly in Japan. In this study, the estimation of the energy consumptions in a kelp aquaculture and three types of fisheries, such as squid, fixed net and gill net, is done for comparison to the consumptions of fisheries in foreign countries. The result reveals that the characteristics of these fisheries’ energy consumptions and the measures for reductions of energy use. Furthermore, in Minamikayabe as surveyed fishing village, the carbon dioxide balance in this village is evaluated. The carbon dioxide emissions from the energy (fuel and electricity) use and the escape Chlorofluorocarbons (CFCs) and Hydrochlorofluorocarbons (HCFCs) from freezers, refrigerators and ice manufacture machines in the village are calculated. Meanwhile, as forests and oceans are carbon dioxide sinks, it is possible to estimate the volume of carbon dioxide stored by woods and seaweed along the coast. Finally, several measures for carbon dioxide reductions are shown.

Marine production and distribution system and Dispersed / Integrated construction of Fishing Ports
There are approximately 3000 fishing ports in Japan and there have been strong criticisms against the dispersed construction of fishing ports. The dispersed construction of the fishing ports is inevitable and historical consequence of the style of the production and life of fishing operators. In recent years, with the fishing production and distribution patterns becoming widespread, and with the advancement of motorization and information technology, the criticism against the investment in dispersed construction of fishing ports is growing furthermore. This paper shows that daily production and living hours of inshore fisheries determine the most of production patterns of the year and so that the dispersed construction of fishing ports in inevitable. Also, this clarifies that some functions of fishing port, considered to be easier for integration than others, such as the function of joint seedlings production, marketing distribution and direct sales to urban consumers, have been in progress of integrations accompanying function-sharing. Also, this paper shows that these dispersed constructions of fishing port are advancing with the merger of the fishery cooperative, which was considered it would push the integration of constructions.Keywords: Fisheries Economics, Dispersed construction, Integrated construction, Marine production and distribution system, Fishing Port
