A regional fishery body (RFB) is a type of international organization that is dedicated to the sustainability of fishery resources in a particular region, or of highly migratory species, whose such capacity has been recognized by the UN Food and Agriculture Organization. An RFB is classified as one of the following two types: regional fishery management organisation (RFMO) regional fishery advisory body (RFAB). RFABs issue non-binding recommendations only, but they are usually organised as more independent, impartial expert bodies, expected to be guided by science rather than political interests of its members. RFMOs are in turn more politicised, but their decisions are binding for the members and subject to enforcement. Therefore, the usually science-focused recommendations issued by the relatively independent RFABs often constitute the scientific input to the RMFOs, where they are subject to political negotiations between the members, in order to adjust them to social and economic reality and to translate them into politically acceptable and tenable binding decisions, which the RMFOs subsequently enforce. In some regions where there are only few actors and they are willing to cooperate on a non-confrontational basis, they may choose to establish a regional fishery management arrangement (RFMA) exercised directly by them rather than to form a more expensive incorporated RFMO. Regional fishery management organisation A regional fishery management organisation (RFMO) is a type of RFB entrusted with sustainable management of fish stocks in a particular region, or of highly migratory species. RFMOs may be classified as belonging to one or more of the three types: General or generic RFMOs which have a wider remit related to living marine resources in general within a region; examples include: Commission for the Conservation of Antarctic Marine Living Resources General Fisheries Commission for the Mediterranean North East Atlantic Fisheries Commission Northwest Atlantic Fisheries Organization North Pacific Fisheries Commission South East Atlantic Fisheries Organisation South Pacific Regional Fisheries Management Organisation Southern Indian Ocean Fisheries Agreement Western and Central Pacific Fisheries Commission Tuna RFMOs are the 5 RFMOs managing tuna stocks: Commission for the Conservation of Southern Bluefin Tuna) International Commission for the Conservation of Atlantic Tunas Indian Ocean Tuna Commission Inter-American Tropical Tuna Commission Western and Central Pacific Fisheries Commission Specialised RFMOs manage certain other species of marine fauna; examples include: North Atlantic Salmon Conservation Organization International Whaling Commission This wide diversity of mandates and areas of application, and also effective implementation of regulations, opens up opportunities
