The objectives of this study were to investigate for the relationship of consumption and substitution between aquaculture species and beef using the Almost Ideal Demand System(AIDS). After the analyses of demand for all farmed raw fishes, it is shown that the own-price elasticity of cultured raw fish has negative value, which is accordant with the demand theory. For the most of the farmed raw fishes, the own-price elasticity came out to be relatively olw, it can be explained by the fact that farmed raw fish are characteristically purchased based more on quality, freshness, taste, health factors, etc than price. Cross-price elasticity between cultured raw fish and beef suggests that farmed raw fish a beef are substitutes of each other, and in between farmed raw fishers, with exception of common sea bream, price change and consumption change correlate, suggesting that the cultured raw fishes have complementary relationship. This is probably because cultured raw fish is mostly consumed in dine out atmosphere by consumers who rather than going out to eat. An the consumer is faced by decision whether he take a meat or raw fish. If they take the raw fish, usually decide on a combination of various platter rather one fish platter.

Laver aquaculture has caused post-harvesting problems such as aggravation of fisheries environment by using inorganic acid in accordance with policies accentuating production increase. These problems resulted in reducing the consumption of laver. Therefore, prior to establishing development plans for laver aquaculture, improvement plans have been described after the analysis of problems concerning the treatment of inorganic acid. While solving this fundamental problem, methods to revitalize the consumption of laver has been drawn in terms of processing, distribution and export. The most important point regarding the solution of the inorganic acid problem is the establishment of an autonomous collective management system through joint-harvesting. And for this, we have considered founding a "Union of Laver Aquaculture Associations" between the associations which cultivate laver. Finally, the establishment of processing and distribution strategies by organizing national campaigns around the 「Day of the Sea」, opening community bazaars, and differentiating purchasers as well as applications of the product, have been proposed. Also, the enlargement of domestic consumers by utilizing e-commerce through the construction of portal service on the Internet has been underlined and the diversification of markets by employing marketing strategies which try to reach foreign consumers directly has been presented.
