The term "shared fish stocks" is understood by FAO (see, in particular, the FAO Code of Conduct for Responsible Fisheries, Article 7 (FAO, 2003b)) to include the following: (a) fish resources crossing the EEZ;  (b) highly migratory species, as set forth in Annex 1 of the 1982 UN Convention on the Law of the Sea (UN, 1982), consisting, primarily, of the major tuna species (being highly migratory in nature, the resources are to be found, both within the coastal State EEZ, and the adjacent high seas); (c) all other fish stocks (with the exception of anadromous/catadromous stocks) that are to be found, both within the coastal State EEZ and the adjacent high seas - straddling stocks; (d) fish stocks to be found exclusively in the high seas - discrete high seas fish stocks. Clearly, these categories are not mutually exclusive. One can find many examples of fish stocks that fall into category (b), or category (c), which also fall into category (a).
