Species items reported in the FAO capture fisheries production database have been classified as oceanic or living on the continental shelf. Catch trends of oceanic species, further subdivided into epipelagic and deep-water species, have been analysed over a 50-year period (1950-99) while statistics for shelf species have been re-assigned to Large Marine Ecosystems (LMEs) for a shorter period (1990-99) and used to investigate catch patterns among the various LMEs.
