More and more fishing vessels are being drawn to the South Pacific each year,
每年有越來越多的漁船被吸引到南太平洋
as this is one of the last oceans where healthy numbers of fish still remain.
因?yàn)檫@是最后幾處魚群數(shù)量仍然保持健康的海域之一
But for how much longer?
可是還能持續(xù)多久?
Fishing is now a high-tech operation,
捕漁現(xiàn)在是高科技作業(yè)
with radar picking up distant flocks of birds that indicate fish feeding below.
由雷達(dá)辨認(rèn) 遠(yuǎn)方顯示水下覓食魚群的海鳥群
The net is paid out in a wide circle around the fish.
撒下的漁網(wǎng)在魚周圍圍成了 一個(gè)巨大的包圍圈
It's a race against time, as the fish could disappear at any moment.
這是場與時(shí)間的賽跑 因?yàn)轸~群會(huì)隨時(shí)消失
As the circle closes, pellets of dye are dropped into the water.
當(dāng)這個(gè)圓收縮 顏料塊被丟到水里
The dye, and the speedboats overhead, discourage the tuna from making a dash through the closing gap in the wall of net.
顏料和上方的高速快艇 使金槍魚喪失沖出收縮中的網(wǎng)墻空隙的信心
As the net closes, a draw-cord running along the bottom of the net is pulled tight.
當(dāng)網(wǎng)收緊 網(wǎng)底部的拉繩被拉緊
The net becomes a bag, or "purse", and the fish are trapped.
漁網(wǎng)成為一個(gè)袋子或"囊"而魚被困住了
There are 150 tonnes of fish in this one haul.
這一網(wǎng)有150噸魚
It used to take a fishing vessel one whole year to catch this many fish.
過去一艘漁船要花一整年才能捕這么多魚
These are mostly yellowfin tuna, plus some skipjack.
大部分是黃鰭金槍魚 加上一些鰹魚
As they're slower breeders than skipjack, many yellowfin are caught before they're old enough to breed.
因?yàn)樗鼈儼l(fā)育比鰹魚更緩慢 許多黃鰭金槍魚在長到能夠繁殖前就被捕撈
This makes them more vulnerable to over-fishing.
這使它們更容易因過度捕撈而受損
