我们回顾了目前关于气候变化对北极海产品生产影响的知识。预计北极海洋食物网将在未来40-100年内发生大规模变化。北极捕捞渔业在气候变化下可能的未来轨迹预测了水生物种进入新水域的运动,并改变了现有物种的动态。预计会对一些鱼类产生负面影响,但其他鱼类,如巴伦支海鳕鱼(Gadus morhua)可能会增加。北极水产养殖约占全球养殖总量的2%,主要由挪威鲑鱼(Salmo salar)养殖组成。在一个更温暖的未来,该行业将面临许多挑战,其中一些已经成为对鲑鱼生长产生负面影响的现实。气候变化的其他更间接的影响,就对北极水产养殖经济状况的影响而言,则更不确定。
We review current knowledge about climate change impacts on Arctic seafood production. Large-scale changes in the Arctic marine food web can be expected for the next 40–100 years. Possible future trajectories under climate change for Arctic capture fisheries anticipate the movement of aquatic species into new waters and changed the dynamics of existing species. Negative consequences are expected for some fish stocks but others like the Barents Sea cod (Gadus morhua) may instead increase. Arctic aquaculture that constitutes about 2% of global farming is mainly made up of Norwegian salmon (Salmo salar) farming. The sector will face many challenges in a warmer future and some of these are already a reality impacting negatively on salmon growth. Other more indirect effects from climate change are more uncertain with respect to impacts on the economic conditions of Arctic aquaculture.
