"Europe Takes Africa’s Fish; Migrants Follow"

Ale Nodye, the son and grandson of fishermen in this northern Senegalese village, said that for the past six years he netted barely enough fish to buy fuel for his boat. So he jumped at the chance for a new beginning. He volunteered to captain a wooden canoe full of 87 Africans to the Canary Islands in the hopes of making their way illegally to Europe.

The 2006 voyage ended badly. He and his passengers were arrested and deported. His cousin died on a similar mission not long afterward.

Nonetheless, Mr. Nodye, 27, said he intended to try again.

“I could be a fisherman there,” he said. “Life is better there. There are no fish in the sea here anymore.”

Many scientists agree. A vast flotilla of industrial trawlers from the European Union, China, Russia and elsewhere, together with an abundance of local boats, have so thoroughly scoured northwest Africa’s ocean floor that major fish populations are collapsing.

That has crippled coastal economies and added to the surge of illegal migrants who brave the high seas in wooden pirogues hoping to reach Europe. While reasons for immigration are as varied as fish species, Europe’s lure has clearly intensified as northwest Africa’s fish population has dwindled.

Last year roughly 31,000 Africans tried to reach the Canary Islands, a prime transit point to Europe, in more than 900 boats. About 6,000 died or disappeared, according to one estimate cited by the United Nations.

The region’s governments bear much of the blame for their fisheries’ decline. Many have allowed a desire for money from foreign fleets to override concern about the long-term health of their fisheries. Illegal fishermen are notoriously common; efforts to control fishing, rare.

But in the view of West African fishermen, Europe is having its fish and eating them, too. Their own waters largely fished out, European nations have steered their heavily subsidized fleets to Africa.

“As Europe has sought to manage its fisheries and to limit its fishing, what we’ve done is to export the overfishing problem elsewhere, particularly to Africa,” said Steve Trent, executive director of the Environmental Justice Foundation, a London-based research group...

Overfishing is hardly limited to African waters. Worldwide, the United Nations Food and Agriculture Organization estimates that 75 percent of fish stocks are overfished or fished to their maximum. But in a poor region like northwest Africa, the consequences are particularly stark.

Fish are the main source of protein for much of the region, but some species are now so scarce that the poor can no longer afford them, said Pierre Failler, senior research fellow for the British Center for Economics and Management of Aquatic Resources...

“The sea is being emptied,” said Moctar Ba, a consultant who once led scientific research programs for Mauritania and West Africa...

Fishermen like Mr. Diouf argue that Africans should have first priority in their own waters — an idea enshrined in a 1994 United Nations treaty on the seas that acknowledges the right of local governments to sell foreigners fishing rights only to their surplus stocks.

But that rule has been repeatedly violated along northwest Africa’s nearly 2,000-mile coast.
