 Climate change will cause key species of fish to migrate towards the poles, badly depleting many commercial fisheries, scientists said in a study published on Thursday.

气候变化导致关键鱼种向北极洄游,严重导致当地经济渔业和衰退.

温水将导致这些鱼类的重新分布,大约每十年移动40公里.

.大西洋鳕当向北方冷水移动时,将下降1/5多.

欧洲鲽已侵入北海,

美国的鳕鱼产量将下降50%.

Some species will face a high risk of extinction, including the striped rock cod in the Antarctic and the St. Paul rock lobster in the Southern Ocean.有些种类将面临来绝, 包括南极的鳕鱼同和南大洋的龙洋.

The disturbing results demonstrate for the first time:

• There will be a large-scale re-distribution of species, with most moving towards the Pole
• On average, fish are likely to shift their distribution by more than 40km per decade and there will be an increasing abundance of more southern species
• Developing countries in the tropics will suffer the biggest loss in catch
• Nordic countries such as Norway will gain with increased catch
• In the North Sea, the northward shift of Atlantic Cod may reduce its abundance by more than 20 per cent, while European plaice - a more southerly fish - may increase by more than 10 per cent
• In the US, there may be a 50 per cent reduction in the number of some cod populations on the east coast by 2050
• Some species will face a high risk of extinction, including Striped Rock Cod in the Antarctic and St Paul Rock Lobster in the Southern Ocean
• The invasion and local extinction of species may disrupt marine ecosystems and biodiversity
