The purpose of this thesis is to clarify present conditions, problems, and essential factors that prompt extensive resource management to secure sustainable production in marine capture fisheries, by way of a case study of the Small-scale Trawling Fishery and Boat Seine Fishery in Seto Inland Sea.

There are a number of reasons to target the Boat Seine Fishery and Small-scale Trawling Fishery for this study. Firstly, the style of fishing observed at these fisheries is the main fishing method in Seto Inland Sea and so is used by many fishermen to earn their living. Secondly, this style of fishing is very efficient. Therefore, there has been a remarkable decrease of fish due to over catching and deterioration of the environment of fishing areas. Thirdly, the resource management of the Small-scale Trawling Fishery and Boat Seine Fishery has been successful due to some important steps established by fisherman to use their fishing areas in a cooperative and comprehensive manner.

It is from this point of view that I shall consider the characteristics of organization, the support of the administrative organ and the continuance factors involved in managing a comprehensive use of the fishing grounds.

The conclusion of this thesis found that six factors are absolutery necessary in order to maintain a sustainable pace of development and extensive resource management in marine capture fisheries, i.e: 1) the promotion of friendship among the fishermen, 2) the sharing of a managerial crisis, 3) the existence of a controller and a leader of organization, 4) the establishment of an observation agency, cooperative resource management rules and a very strict penalty system for offenders, 5) the inspection of resource management effects on marine capture fisheries, 6) the establishment of a higher-level administrative that aims to increase the fishermen’s motivations that prompt an extensive resource management.

Canadian snow crab landings accounts for 57.4% of the world landings and she exports almost her products to major market, Japan and U.S. Prices of snow crab has been fluctuated depend on, they say, ‘World Market’, which is section products market. The reasons why Canada had become a major exporter in 1990’ are followings. 1) Landings has increased, 2) Her products could entry into U.S. market as substitute of Alaskan snow crab 3) Canadian producers change to section procession from meat procession with Japanese technical introduction. Although Canada is a major exporter, Canadian producers could not conduct enough marketing activity.

In the 1980’s, Taiwanese small-scale tuna longliners lost their traditional fishing grounds owing to the implementation of Exclusive Economic Zones (EEZs), and they also encountered worsening operation problems due to insufficient fishing laborers and fishery resource shortage. Along with the gradual expansion of Taiwanese small-scale tuna longliners to fishing grounds abroad, the operation problems not only improved, but the production and export quantity of fresh tuna in Indonesia also has been greatly affected and increased consequently. This article tries to explore those affecting factors during the period when Taiwanese small-scale tuna longliners enlarged the fishing grounds overseas into Indonesian waters as well as the operation strategy used by them. The article also analyzes the characteristics for the Indonesian government to develop the tuna fishing industry in different periods and the policy change in terms of the tuna fishery; the methods that Taiwanese small-scale tuna longliners adopted in terms of systems for fishing access fees; vessel charter agreement and joint venture; and, the operation strategy used to comply with policy modification in Indonesia.

This paper aimed at arguing about the public financial support for a traditional fishing and the tourist industry which utilized it. We investigated about the Cormorant Fishing in Nagara-river, Gifu.

First, we clarified about the present condition of the Cormorant Fishing and Gifu City Cormorant Fishing Viewing Boat enterprise (GCF). Since the Cormorant Fishing cannot become independent, it is utilized as tourist attractions. On the other hand, Cormorant Fishing offers various external effects. In this paper, we pointed out that political decision-making of the public financial support should have been performed in consideration of the external effect, and measured the recreation-effect. We evaluated a part of the external effect with which the Cormorant Fishing provides visitors using Travel Cost Method (TCM).

As results of analyses, it became clear that its benefit is about only 10% of additional public financial support. However, Cormorant Fishing has existence value and bequest value of a national level while producing the economic effect to this area. It is necessary to judge about the right or wrong of public financial support based on evaluation of these effects.
