脆弱天堂 19

These fishermen are superstitious about turtles.

Bringing one on board is bad luck.

It's her lucky day.

More and more fishing vessels are being drawn to the South Pacific each year

As this is one of the last oceans where healthy numbers of fish still remain.

But for how much longer?

Fishing is now a high-tech operation

With radar picking up distant flocks of birds that indicate fish feeding below.

The net is paid out in a wide circle around the fish.

It's a race against time, as the fish could disappear at any moment.

As the circle closes, pellets of dye are dropped into the water.

The dye, and the speedboats overhead

Discourage the tuna from making a dash through the closing gap in the wall of net.

As the net closes, a draw-cord running along the bottom of the net is pulled tight

The net becomes a bag, or ''purse'', and the fish are trapped.
