The purpose of this publication is to present considerations which can serve as the basis for potential cooperation between RFBs and RSCs. It describes the concept of ecosystem-based fisheries management, the relevant mandates and activities of RFBs and RFCs and the relationship and mutual relevance of their work. Possible mechanisms for cooperation, and issues for future consideration, are identified. It is anticipated that such cooperation could best be implemented on a site-specific or regional basis, after initial consideration at the global level by RFBs and RSCs.
