Freezing Preservation of Fresh Antarctic Krill (Euphausia superba)

南极磷虾之冻结贮藏研究

Effect of Antarctic Krill on the Nutritional Physiology in the Growing Rat

南极虾对生长中白老鼠之营养生理影响

An oncoming ice age made the ocean water cold. High winds mixed the water in the ocean faster than before. Rain and snow made more nutrients run off from the land into the water. The nutrients resulted in algae. That attracted small fish and shrimp called krill .

随即而来的冰河时代（指第四纪冰期）使得海水变得冰冷。狂风使得海水融合得比以前更快。雨雪使得更多的营养物质从陆地流入水中。这种养分产生了藻类，吸引了小鱼和磷虾。

Baleen whales suck in mouthfuls of water and extract small organisms such as krill , using fibrous buccal filters.

须鲸，用纤维状的口腔过滤器吸入大量的水，并从磷虾等小生物中吸取营养。

Researchers have long known that a sizeable portion of the seals’ diet is made up of krill .

研究者们很早就知道在豹海豹的食谱中一大部分是由磷虾组成。

Some researchers have theorised that the seals might suck water into their mouths and swish it past their closed teeth to capture krill .

一些研究者们从理论角度分析豹海豹也许可以通过先入吸海水再闭紧牙齿将海水吐出的筛选法捕捉磷虾。

The year 2004 was a poor krill year at South Georgia, and 2009 has been a very bad one.

2004年南乔治亚岛仅出现少得可怜的磷虾，而2009年则更坏。

Plankton is essentially anything living in water that is too small to swim against the current, including krill and algae.

浮游生物是生活在水中的一切，包括磷虾和藻类，它们小到不能逆流而行。

No one thinks krill are yet endangered, but no one fully understands them.

没有人相信磷虾也处于濒危，但是没有人完全了解它们。

A trend often masquerades as a cycle at the start, and evidence suggests that these scarce krill years may foreshadow a new South Georgia.

趋势通常表现出新一轮循环起点的假象，有证据表明这些磷虾稀少的年份可能预示着一个新的南乔治亚。

图7：成群的磷虾是整个南极动物食物链的基础。它们以浮游生物为食，生长在海冰的上层。

The fear is that devastating the krill population will set in train a series of changes that will affect other creatures.

一个担心是，损坏了磷虾种群数量将引起一系列影响其它生物的变化。

When the gulf waters freeze over during the Antarctic winter, they hunt for the krill that lives underneath the ice surface.

在南极洲的冬天，海湾的水面都被冻住了，它们就会去捕捉冰层下面的磷虾为食。

This could be a good thing, of course. More algae might mean more krill , and that might mean more whales and other large sea animals.

这当然是个好事，更多的藻类意味着有更多的虾类，更多的虾类意味着将有更多的鲸类和其它大型海洋动物。

One of the most recent objects of concern is a small, shrimp-like creature called krill , which is now being fished in a big way.

最近令人担忧的是，一种被称为磷虾的类似小虾的小生物，正在被大规模捕捞。
