Abstract

Profound indirect ecosystem effects of over-fishing have been shown for coastal systems such as coral reefs and kelp forests. A new study from the ecosystem off the Canadian east coast now reveals that the elimination of large predatory fish can also cause marked cascading effects on the pelagic food web. Overall, the view emerges that, in a range of marine ecosystems, the effects of fisheries extend well beyond the collapse of fish exploited stocks.

摘要

过度捕捞对珊瑚礁和海带森林等沿海生态系统产生了深远的间接生态系统影响。加拿大东海岸生态系统的一项新研究表明，大型掠食性鱼类的消失也会对远洋食物网产生显著的级联效应。总体而言，人们逐渐认识到，在一系列海洋生态系统中，渔业的影响远远超出了被捕捞鱼类种群的崩溃。
