The widespread implementation of extended fisheries jurisdiction (EFJ) through out the world has meant that substantial fishery resources, which hitherto had been international common property, have become the property of coastal states. One question that this development raises is what is the future role of cooperative fisheries arrangements between coastal states and distant-water nations in the newly created zones. Although many coastal states at the dawn of EFJ viewed cooperative fishery arrangements largely as temporary expedients, the economics of such arrangements indicate that coastal states in the Pacific and elsewhere would benefit from maintaining many, and perhaps most, such arrangements on a permanent basis. This is true whether the coastal states are developing or developed. However, the opportunities for long-term cooperative arrangements in the Pacific and elsewhere are endangered by uncertainties and ambiguities in coastal states' rights to the fishery resources within their zones. Two major sources of uncertainly are the inadequate management capacity of some coastal states and the transboundary nature of many of the stocks in their waters
