Off the coast of Malta, bobbing in the Mediterranean waters, a flotilla of fishing boats is waiting to net swarms of bluefin tuna before the catching season ends last this month.
The tuna aren’t the only ones being hunted.
Environmental campaigners are waiting too, their binoculars and monitoring devices trained not on the sea but on the trawlers.
“Actually, I want them to start fishing,” said Oliver Knowles, a campaigner for Greenpeace, which wants a moratorium on bluefin tuna fishing and has sent two ships to the Mediterranean to try to disrupt the hunt.
“You want a little environmental destruction, so you get to say something about it,” he told his young crew of 26 on board the organization’s flagship Rainbow Warrior.
“There’s a perversity about being a campaigner — you have to hope for some bad news. I don’t want them
to fish.
“But actually, unless we raise the political temperature on this, and get them to stop, they can come back year after year after year.”
At any one time there are a dozen or more vessels in an area large enough for them to remain out of sight of each other. From France, Spain, Turkey and elsewhere. Some barely move, others shift constantly.
Big in Japan
Many of the boats carry net cages used to encircle the tuna swarms, which are then towed offshore to be fattened and shipped in giant freezer ships to Japan, where it is a mainstay of sushi and sashimi.
The larger and fatter, the more valuable they are — the biggest specimens can fetch more than US$100,000 at the Tsukiji fish market in Tokyo.
Industrial-scale fishing and harvesting on the high seas has caused stocks to plunge by up to 80 percent in the Mediterranean and eastern Atlantic, where they come to spawn in the warmer waters.
Earlier this year the EU and the US attempted to ban the trade of the species, but Japan lobbied successfully and the proposal was defeated.
The focus has now returned to the open waters until the tuna season ends on June 15, and Greenpeace flew reporters by helicopter onto the Rainbow Warrior to follow its side of the chase.
Leaning over nautical maps and compasses, Knowles and his crew monitor the trawlers, looking for signs they might have found a swarm.
“If they start circling or their speed slows down,” he said, “it’s usually an indication that they at least think they’ve got a shoal of fish.”
That’s the point when the Greenpeace activists want to step in to disrupt any fishing to “stop them taking the fish out of the water,” said Knowles.
Greenpeace refuses to divulge what kind of tactics it might employ. Last month, activists on board rafts temporarily blocked three tuna fishing vessels from leaving the port of Sete, in southern France.
Waiting for action
There is little time left. The wrangling over a ban piled further pressure on the International Commission for the Conservation of Atlantic Tunas (ICCAT) to shorten the fishing season to four weeks this year and shrink the quota of bluefin tuna that can be caught from 19,500 tonnes to 13,500 tonnes in 2010.
“Most scientists thought the quotas were higher than they should be,” said Audun Lem, a fishery trade expert at the Food and Agriculture Organization.
Italy went further and imposed a moratorium on industrial fishing of tuna this year, paying its fishermen and companies US$12.3 million to keep their boats at harbor.
The 49-strong tuna fleet, now being reduced to nine, “was subsidized to be built. It is now subsidized to stay at home. And it will be subsidized to be destroyed,” said Francois Chartier, a campaigner on board the Arctic Sunrise, the other Greenpeace vessel in the Mediterranean. “It is a total aberration.”
If everyone respected their quota, “we should have an improvement” in the situation, said Massimo Spagnolo, who heads a research institute close to the fishing industry.
Spagnolo, who says quotas are not a good idea because they encourage early and intensive fishing before
the tuna can spawn, believes ICCAT has overstated the danger facing
the species.
“If you go to the Tirrenian Sea there is a lot of tuna,” he said, referring to waters off Italy’s west coast.
South of Malta, however, it’s apparently not warm enough yet to draw tuna. The Rainbow Warrior has been at sea for more than a week but hasn’t been able to disrupt any fishing.
“There’s a good selection of vessels all around us,” Knowles said. “We’ll just have to keep watching. We just have to be patient.”
In late October of 1873 the government of Japan decided against sending a military expedition to Korea to force that nation to open trade relations. Across the government supporters of the expedition resigned immediately. The spectacle of revolt by disaffected samurai began to loom over Japanese politics. In January of 1874 disaffected samurai attacked a senior minister in Tokyo. A month later, a group of pro-Korea expedition and anti-foreign elements from Saga prefecture in Kyushu revolted, driven in part by high food prices stemming from poor harvests. Their leader, according to Edward Drea’s classic Japan’s Imperial Army, was a samurai
Located down a sideroad in old Wanhua District (萬華區), Waley Art (水谷藝術) has an established reputation for curating some of the more provocative indie art exhibitions in Taipei. And this month is no exception. Beyond the innocuous facade of a shophouse, the full three stories of the gallery space (including the basement) have been taken over by photographs, installation videos and abstract images courtesy of two creatives who hail from the opposite ends of the earth, Taiwan’s Hsu Yi-ting (許懿婷) and Germany’s Benjamin Janzen. “In 2019, I had an art residency in Europe,” Hsu says. “I met Benjamin in the lobby
April 22 to April 28 The true identity of the mastermind behind the Demon Gang (魔鬼黨) was undoubtedly on the minds of countless schoolchildren in late 1958. In the days leading up to the big reveal, more than 10,000 guesses were sent to Ta Hwa Publishing Co (大華文化社) for a chance to win prizes. The smash success of the comic series Great Battle Against the Demon Gang (大戰魔鬼黨) came as a surprise to author Yeh Hung-chia (葉宏甲), who had long given up on his dream after being jailed for 10 months in 1947 over political cartoons.

A fossil jawbone found by a British girl and her father on a beach in Somerset, England belongs to a gigantic marine reptile dating to 202 million years ago that appears to have been among the largest animals ever on Earth. Researchers said on Wednesday the bone, called a surangular, was from a type of ocean-going reptile called an ichthyosaur. Based on its dimensions compared to the same bone in closely related ichthyosaurs, the researchers estimated that the Triassic Period creature, which they named Ichthyotitan severnensis, was between 22-26 meters long. That would make it perhaps the largest-known marine reptile and would
