This document describes highly migratory fish stocks, straddling fish stocks, and stocks of other high-seas fishery resources and the fisheries for them, including information on their state of exploitation. Fisheries for highly migratory species are important in all oceans and semi-enclosed seas, except for polar regions. Fisheries for straddling fish stocks are much more localized, primarily occurring in a few regions where continental shelves extend beyond the 200-mile exclusive economic zone (EEZ) while most fisheries for other high-seas fishery resources are deep-water fisheries. Formal assessments are lacking for most of the stocks examined. Nevertheless, the compilation of available assessments and FAO's analyses indicate that about 30 percent of the stocks of highly migratory tuna and tuna-like species, more than 50 percent of the highly migratory oceanic sharks and nearly two-thirds of the straddling stocks and the stocks of other high-seas fishery resources are overexploited or depleted.
