The purpose of this thesis is to study models of international fisheries management and attempt to analyse under what circumstances there will be conflicts and how can these conflicts be solved. The central model framework that we use is cooperative game theory. We use this framework to study the possibilities, conditions and stability of cooperation in high seas fisheries. The cooperative game theory framework is constructed using the traditional differential games in fisheries economics. This general theoretical framework is then applied to the case of Norwegian spring-spawning herring where we use a discrete time and age-structured population dynamics model as a basis for cooperative game models and risk analysis. We show that external and internal stability of cooperation depends on several factors including technological efficiency and harvesting costs. Furthermore, the problem of uncertainty may be avoided by simple adaptive modifications to the full cooperation strategy. The international management of herring is very important since stock variations and the risk of depletion are relatively high. This is shown in a risk analysis part of the thesis.
