were between them taking twice as many fish from the sea as they had just twenty-five years earlier. 它们每年从海里的捕鱼量是25年前的两倍。
Trawlers are sometimes now as big as cruise ships and haul behind them nets big enough to hold a dozen jumbo jets. 现在的拖网渔船有时候大得很像巡洋舰,后面拖的网大得能装下十几架大型客机。
Some even use spotter planes to locate shoals of fish from the air. 有的甚至使用侦察机从空中寻找鱼群。
It is estimated that about a quarter of every fishing net hauled up contains "by-catch", 据估计,每拖上来一网,大约有四分之一是“无意捕获物”,
fish that can't be landed because they are too small or of the wrong type or caught in the wrong season. 即因为太小而抓不住的鱼,或不该捞的鱼,或不该在那个季节捕的鱼。
As one observer told the Economist 1: "We're still in the Dark Ages. We just drop a net down and see what comes up." 正如一位观察员对《经济学家》杂志说的:“我们仍处于愚昧黑暗时代。我们只是把网一撤,看看能捞上来什么。”
Perhaps as much as twenty-two million metric tons of such unwanted fish are dumped back in the sea each year, mostly in the form of corpses 2. 每年大约有多达2200万吨这类不要的鱼倒回海里,大多数是以尸体的形式。
For every pound of shrimp 3 harvested, about four pounds of fish and other marine 4 creatures are destroyed. 每收获1千克虾,就有大约4千克鱼和别的海洋动物遭受灭顶之灾。

a degree of disturbance 5 that no ecosystem 6 can withstand. 哪个生态系统也受不了这等干扰。
At least two-thirds of species in the North Sea, by many estimates, are being overfished. 据许多人估计,北海至少有三分之二的鱼类处于过捕捞的状态。
Across the Atlantic things are no better. 在新英格兰近海,
Halibut once abounded 7 in such numbers off New England that individual boats could land twenty thousand pounds of it in a day. 原来大比目鱼如此之多,分散的渔船一天可以捕捞到9000多千克。
Now halibut is all but extinct off the northeast coast of North America. 如今,大比目鱼在美国东北海岸附近几乎已经灭绝。
