Regional Fishery Bodies Map Viewer. Regional Fishery Bodies (RFBs) are a mechanism through which States or organizations that are parties to an international fishery agreement or ("agreement" is fundamental, and different from arrangement) arrangement work together towards the conservation, management and/or development of fisheries. (Some RFBs, especially those with an ecosystem mandate, work with seabirds, etc that are connected with fisheries but are not fish stocks per se.)
