Global warming will not necessarily change the amount of fish caught half a century from now, but it will shift catches away from the tropics toward the poles, researchers reported. The researchers, from the University of British Columbia and elsewhere, used a computer model including environmental factors and data on 1,066 fish species ranging from sharks to shrimplike creatures at the bottom of the food chain. Together those species accounted for most of the world's catch from 2000 to 2004. The findings were reported in the journal Global Change Biology. By 2055, the scientists predicted, countries like China, Chile, Indonesia and the United States (excepting Alaska and Hawaii) will see catches decline, while catches off Alaska, Greenland, Norway and Russia will rise.
