The International law of the sea is undergoing significant changes affecting the use and enjoyment of marine fishery resources. The effects of these changes, however, are quite dissimilar among the different regions of the world, because of the wide disparity in the characteristics and geography of the coastal states and the fishery resources. The only common element that all regions share is the necessity for improvements in systems for the management of the resources and the distribution of the resource benefits. Few, if any coastal states are adequately prepared to deal with the consequences of extended jurisdiction, either in terms of managing the newly acquired wealth or in terms of ensuring that their fishermen have reasonable access to the zones of other countries. As the changes in the law of the sea take place, the gap between the problems and competence to deal with the problems is likely to result in increases in the economic and biological waste of resources and in conflicts among countries. The general purpose of this study is to help stimulate improved competence to deal with these problems of waste and conflict. It seeks to do this by examining the nature of the changes taking place in two neighboring but fundamentally different regions --Southeast Asia and the Southwest Pacific. The study also attempts to identify some of the major problems that are emerging, and then to suggest some approaches and strategies that might be followed'by coastal states in dealirig with the problems.
