Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked.

而且早期用延绳钓捕鱼的时候， 有许多鱼在上钩后就被鲨鱼吃了。

Conservationists say longline gear also damages corals and other important habitat on the sea bottom, threatening both the turtles and the fish.

环保人士称延绳钓也破坏了海底的珊瑚和对其它动植物来说很重要的海底栖息地，对鱼类和海龟都造成威胁。

He says he quit when he saw dolphins, caught accidentally on longline hooks, being dragged aboard ship, beaten to death, and thrown back into the sea.

他说，当他看到长线鱼钩意外捞到海豚，人们把它们拖上船，打死，又给扔到海里时，他不干了。

The Spanish fleet of so-called surface longline fishing boats ostensibly targets swordfish, but 70 per cent of its catch, by weight, from 2000 to 2004 were pelagic sharks.

西班牙所谓的拖网渔船船队表面上是以旗鱼为目标，但从2000年到2004年，它70%按重量计算的捕获物是深海鲨鱼。

Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around now.

因为没有足够的鱼钩来诱捕，某些鱼就逃过一劫，这会导致对以往鱼类资源存量的低估，再者，在早期的延绳钓时代，许多已经勾住的鱼会落入鲨鱼的口中。
