BELL FROM THE NATAL QUEEN: For many years the iron barque, Natal Queen, traded between Tasmania and mainland ports.

While the results necessarily remain uncertain, they undoubtedly represent our most complete picture yet of the global state of fish catches." Worm said the world's fisheries were being over-exploited but that some stocks were being sustainably managed: "Where such measures have been taken, we find that both fish and fishermen are more likely to persist into the future." Global fish catches rose from the 1950s to 1996 as fishing fleets expanded and discovered new fish stocks to exploit.

But after 1996, few undiscovered fisheries were left and catches started to decline.

Prof Daniel Pauly, at the University of British Columbia in Canada and who led the work, said the decline is very strong and "is due to countries having fished too much and having exhausted one fishery after another." Prof Boris Worm, at Dalhousie University in Canada and not involved in the new research said.

"This was a Herculean task that no one else has ever attempted.

Illegal and pirate fishing take place in many parts of the world.

Prof Callum Roberts, at the University of York in the UK and not part of Pauly's team, said: "We can see more clearly now, for example, the immense value of fish to poor people in developing countries," he said.

"We can see how industrial fisheries from developing countries are robbing these people of livelihoods and food.

We can also see, that in efforts to stem declines, we have been using more and more bycatch that was once thrown away." Seabirds have been around for sixty million years, and they are true survivalists: circumnavigating the globe without rest, diving more than 200 meters in treacherous seas for food, braving unpredictable weather and finding their way with few, if any, landmarks.
