脆弱天堂 21

The fish are scooped up from the water, a tonne or two at a time.

Every last fish from this school of 7,000 yellowfin and skipjack tuna

is plucked from the water.

With fishing techniques now so efficient

And with ever more vessels plying the Pacific

There is real concern among biologists

That even the resilient skipjack may begin to decline.

This vessel is not one of the newcomers.

It's a Papua New Guinea-flagged ship, fishing in their territorial waters.

So it's subject to catch limits and regulations

that are amongst the strictest in the Pacific

Designed to ensure that tuna fishing remains sustainable.

But New Guinea's fishermen are concerned about the increasing numbers

of foreign vessels now fishing for Pacific tuna.

They were the first nation to propose

that the high seas pockets beyond their national waters be declared marine reserves

As now advocated by Greenpeace.
