Catching fish for the purpose of [[food]] or [[sport]] is known as [[fishing]]. The annual [[yield]] from all [[fishery|fisheries]] worldwide is about 100 [[million]] [[tonne]]s. [[Overfishing]] is a threat to many species of fish. On [[May 15]] [[2003]], the journal ''[[Nature (journal)|Nature]]'' reported that all large [[ocean]]ic fish species worldwide had been so systematically over caught that fewer than 10% of 1950 levels remained. [http://www.globeandmail.com/servlet/story/RTGAM.20030514.wfish1405/BNStory/National/] Particularly imperiled were [[shark]]s, Atlantic [[cod]], [[Bluefin tuna]], and Pacific [[sardine]]s. The authors recommended immediate drastic cutbacks in fish catches and reservation of ocean [[habitat (ecology)|habitats]] worldwide. |
