And often residents are the first to discover a nasty spill or a fish kill in their area.

通常情况下都是普通的居民第一时间发现污物排放到河流里，或发现水里出现死鱼。

The cause of the fish kill has not yet been determined, but the area they were discovered in was impacted by oil from the BP oil spill.

鱼的死亡原因尚未确定，但是它们被发现的区域受到英国石油公司泄漏原油的影响。

It would make sense to give the fish enough time to recover, grow to full sizes and reproduce, then catch them in a way that doesn't kill other innocent sea life.

给这些鱼足够的时间来恢复、成长和繁殖，然后以一种不会杀死其他无辜海洋生物的方式来捕获它们，这是有意义的。

In such places red tides tend to form, some producing toxins that get into the food chain through shellfish and rise up to kill bigger fish (if there are any left), birds and even seals and manatees.

在这样的地方赤潮容易形成，有些会产生毒素，毒素通过贝壳动物进入食物链，并且增多而杀死较大的鱼(如果还有任何剩下来的话)、鸟，甚至海豹和海牛。

Some are genetically engineered on fish farms, while the rest are hooked by the mouth or netted by huge trawlers that catch and kill everything in their path.

有些是养鱼场基因改造的鱼，其余的则是嘴被钩住或是被巨大的拖网渔船网住，拖网渔船所过之处一路捕杀。
