A new global study concludes that 90 percent of all large fishes have disappeared from the world's oceans in the past half century, the devastating result of industrial fishing.
The study, which took 10 years to complete and was published in the international journal Nature this week, paints a grim picture of the Earth's current populations of such species as sharks, swordfish, tuna and marlin.
The authors used data going back 47 years from nine oceanic and four continental shelf systems, ranging from the tropics to the Antarctic. Whether off the coast of Newfoundland, Canada, or in the Gulf of Thailand, the findings were dire, according to the authors.
"I think the point is there is nowhere left in the ocean not overfished," said Ransom Myers, a fisheries biologist at Dalhousie University in Halifax, Nova Scotia and lead author of the study.
