| | | Tuna and billfish catches |
| |
|  Whatever its sources might be, natural variability adds to the uncertainty about the working of exploited ecosystems, their resilience to human impacts and their capacity to recover from serious disturbances. It therefore contributes to the need for wide implementation of the precautionary approach to fisheries. Tuna and tuna-like species are found in the Atlantic, Indian and Pacific Oceans and in the Mediterranean Sea. They are economically very important as well as a significant source of food. | | | | The world production of tuna and tuna-like species has increased continuously from less than 0.6 million tonnes in 1950 to 5.7 million tonnes in 2000 (FAO's most recent statistics). That year, the catch of tuna and tuna-like species accounted for about 8.5 percent of the total production of marine finfishes.The 2000 total catches of the principal market tuna species and all billfishes represent 63 and 2.5 percent, respectively, of all tuna and tuna-like species. With the exception of swordfish, billfishes are captured mainly by recreational fisheries and as by-catches of commercial tuna fisheries. | | | | Since 1995, FAO's Marine Resources Service has been collecting catch data for tuna and tuna-like species in order to present this information in an atlas on the global distribution of catches. The Atlas (only accessible via Internet) presents the global distribution of catches at a resolution of 5° latitude by 5° longitude for all tuna and tuna-like species. These species consist of the so-called principal market tunas and some billfishes, as listed below (scientific names are given in brackets followed by the FAO abbreviation in upper case): | | | | PRINCIPAL MARKET TUNASBILLFISHESalbacore (Thunnus alalunga), ALBAtlantic blue marlin (Makaira nigricans), BUMbigeye tuna (Thunnus obesus), BETAtlantic white marlin (Tetrapturus albidus), WHMnorthern bluefin tuna (Thunnus thynnus), BFTblack marlin (Makaira indica), BLMskipjack tuna (Katsuwonus pelamis), SKJIndo-Pacific blue marlin (Makaira mazara), BLZsouthern bluefin tuna (Thunnus maccoyii), SBFstriped marlin (Tetrapturus audax), MLSyellowfin tuna (Thunnus albacares), YFTswordfish (Xiphias gladius), SWO | | | | Whatever its sources might be, natural variability adds to the uncertainty about the working of exploited ecosystems, their resilience to human impacts and their capacity to recover from serious disturbances.
