Seaweed is a nursery for all these large pelagic fish.

对所有这些大型中上层鱼来说，海藻是它们的温床。

But pelagic fishing only runs 6 months a year.

但是，一中能出海的机会只有半。

Young polar cod are pelagic, meaning they live at or near the surface.

幼的极地鲟鱼是海洋生物，也就是说他们生活在或者接近海平面。

Most free-swimming sea creatures are pelagic.

大多数自由移动的海洋生物都是海面生物。

But pelagic sharks are used to being able to swim long distances without obstructions, changing directions only as they please.

但是高阶的鲨鱼习惯于长时间在没有障碍物的环境下，能够随心所欲地改变方向游泳。

And we haven't even gotten into the whole mercury thing yet, where migratory Pelagic fish like tuna absorb toxic metals.

我们还没说到有害物质呢，洄游的大洋性鱼，金枪鱼会吸收有害金属。

So, as far as we know, it was not a deep water kind of species or an open ocean, we call pelagic species.

所以就我们所知，它不是我们称作远洋物种的深海物种或是外海物种。

" Offshore" killer whales, up to 6.6 metres long, patrol distant waters in pods of 100 to 200 individuals, hunting pelagic fishes like sharks.

“远洋鲸”长达6.6米，以100至200头的群体在遥远水域巡逻，捕食鲨鱼等中上层鱼。

I mean, a lot of times I think that the open pelagic water ecologists do feel a bit hard done by because, you know, it's the bit that you have to get through to get to the seabed.

我的意思是， 很多时候我觉得开阔的远洋水域生态学家确实感到有些被忽视，因为你知道， 这片区域只是你前往海底途中必须经过的部分。
