灰熊卓越的捕鱼技巧

Grizzly bear's amazing salmon catching techniques - BBC

成千上万的大马哈鱼
Salmon, returning to spawn,
正归来产卵
in their thousands.
这些灰熊是首批来捕获营养美食的客人
These bears are first in line for a nutritious catch.
由于荷尔蒙的变化
Triggered by hormonal changes,
灰熊现在进入了暴饮暴食的阶段
the grizzly bears now enter a phase of hyperphagia.
这使得它们每天可以连续吃上20个小时
This allows them to eat constantly for up to 20 hours a day,
也不会有饱腹感
without ever feeling full.
它们一天可以消耗高达10万卡路里的热量
They can consume up to 100,000 calories in a single day.
大马哈鱼数量如此之多 灰熊可以只挑鱼的一部分食用
And given the abundance of salmon, they can afford to be picky.
就好似热带地区的熊一样
Just like the bears in the tropics,
它们只吃拥有最高级能量的部分
they seek out the highest form of energy.
只挑选富含脂肪的鱼卵 鱼皮和鱼脑食用
Selecting only the fat rich eggs, the skin and brain of the fish.
在开阔水域 这并不总是容易的
In open water, it’s not always easy.
但随着大马哈鱼向上游迁徙
But as the salmon move further upstream,
灰熊们也来到了这里
the grizzlies are here too.
在河道变窄的地方更容易捕到鱼
Where the river narrows it will be easier to land a catch.
