Management of high sea fisheries

Objective

The intergovernmental UN Conference on Highly Migratory and Straddling Stocks (1993-95) addressed the management of fishery resources found both within the coastal state 200 mile Exclusive Economic Zone (EEZ) and the adjacent high seas. During the negotiation process, a number of suggestions were designed to solve the contradiction between the rights and duties of the coastal states and the distant water nations and to improve cooperation between fishing nations. A consensus was reached on that the management of straddling and highly migratory fish stocks is to be carried out through regional fisheries management organisations
Research has been undertaken with regard to both parts.

As regards part 1), management issues regarding straddling and highly migratory fish stocks have been reviewed. Preliminary analysis of some alternative cooperative management regimes has been undertaken.

As regards part 2), models of population dynamics have been developed for both Norwegian spring spawning herring and Atlantic bluefin tuna. Furthermore, available cost, effort, harvest and revenue data have been collected, and preliminary estimations of cost and harvest functions have been undertaken.

Our research consists of two parts:
1) Theoretical analyses of the UN negotiation process, the implication of the negotiation text produced to the international exploitation of marine resources, and possible regional arrangement on the management of straddling and highly migratory fish stocks. The prevailing methodologies applied are economic analysis, game theory and decision analysis.
2) Detailed economic analyses of two case studies that are important to the European Union.

One of the cases is the Norwegian spring spawning (Atlanto-Scandinan) herring, exploited by Norway, Russia, Iceland, the Faroe Islands and several EU countries. The other case is Atlantic bluefin tuna, exploited by a number of EU countries.
