The breeding population of bluefin tuna in the Eastern Atlantic and the Mediterranean has collapsed, in what may come to be seen as one of the world’s most spectacular ecological disasters, according to an independent report.
The destruction of stocks of one of the world’s most expensive fish, already recognised as being as endangered as the giant panda, effectively took place in 2007, more than twice the legal catch was taken by Mediterranean fishermen under the eyes of EU and UN-recognised officials, according to the report.

If the analysis of the size and weight of tuna now passing through the Japanese market is representative of what remains in the sea, according to the report, the EU and other Atlantic nations have presided over disaster comparable to that of the collapse of the blue whale or the Northern cod.
Environmentalists blame the final destruction of what was the largest population of a fish which is known to have been hunted for 7,000 years on a catastrophic failure of governance by the EU and the International Commission for the Conservation of Atlantic Tunas (ICCAT).
Rampant illegal fishing with spotter aircraft, fast power-boats and the full modern hi-tech arsenal of fishing technology has hastened the decline.
A-list diners, including Charlize Theron, Sting and Elle Macpherson signed a letter of protest last week to Nobu Matsuhisa, the world-famous fushion chef, threatening to boycott his restaurants unless he takes the endangered bluefin tuna off the menu.
According to the latest report, released to coincide with World Oceans Day by the independent consultant Roberto Mielgo, 70 per cent of the bluefin tuna in the Japanese market between July 1 last year and May 1 this year were below 90 kilos in weight.
Some 33 per cent of the tunas on the Japanese market were below the legal size of 30 kg when caught – a major indictment of the inspection regime run by Mediterranean countries under the supervision of ICCAT.
Mr Mielgo said: “If this analysis of what is on the Japanese auction markets corresponds to what is left in the sea, we are in deep trouble. It means the adult bluefins are no longer there. If that is what is at sea, the stock will not recoup.
“My view is that the stock collapsed in 2007 as a result of the 2007 fishing season in which 61,000 tons of bluefin were caught. The fishery should have been closed in 2007.”
The 61,000 tons recorded in official catch figures in 2007 was twice the legal quota agreed by EU nations and ICCAT, four times what scientists advised was responsible and six times what ICCAT’s own scientists said was needed for the recovery of the stock.
Ten years ago, the majority of bluefin tuna in the Japanese market were medium-sized mature adults of 120 kgs or more and the stock structure wholly different to what it is now. Now a third of it is below the minimum landing size and causing concern even among Japanese tuna traders who dislike selling small fish.
Mr Mielgo’s report concludes: “The massive presence in the Japanese market of juvenile bluefin tunas having been illegally caught and farmed points to the failure of current control schemes, including the credibility of observers filling in caging declarations.”
Mr Mielgo is a tuna farmer turned whistle-blower. The report by his consultancy, Advanced Tuna Ranching Technologies, goes even further than trends presented earlier this year by WWF using official figures which showed that the population of breeding tuna in 2007 was only a quarter of that 50 years ago.
According to WWF’s analysis, the bluefin breeding population will disappear by 2012 under the current fishing regime. It called for the immediate closure of the fishery.
Mr Mielgo’s report says the age-profile of tunas on the Japanese market “is consistent with the hypothesis of an on-going collapse of the breeding population of this stock.”
He added: “It’s not that I am a pessimist. There is no way this population is going to pick up. Again, I hope I am wrong. The fish are not there.”
Dr Sergi Tudela, head of fisheries for the Mediterranean, said: “Our position in April, based on ICCAT data, is that the spawning stock will have been wiped out by 2012.
“This new data is a further indication of what we said then, which is that the spawners are disappearing. The reproducing stock is in serious trouble. This shows the bluefin is in dire straits.”
Mr Mielgo is featured in the film, The End of the Line, which has its national public premiere in 50 British cinemas tomorrow.
The End of the Line has been cropping up on blogs and news sites, and is receiving some very positive feedback.
Recent comments on the film and the campaign have appeared on the Washington Post, California Chronicle, Spear’s WMS (Wealth Management Survey) and Whole Food Market’s blog. Here is a round-up of the coverage the film is receiving.
Charles Clover answers questions about the film and it’s message for the Washington Post’s All We Can Eat food blog.
Asked whether it is too late to save the oceans, he replies: “No. But part of the problem is that people still believe we live in a world of plenty. The world of plenty in terms of fish disappeared in 1988, and we haven’t caught up with that fact yet.”
He goes on to deal with the issue of farming carniverous fish: “It takes five pounds of little fish to grow one pound of salmon. And actually those fish, like Peruvian anchoveta and blue whiting, eat very nicely. So why don’t we eat the little fish?”
In an opinion piece for Spear’s WMS, William Sitwell, Editor of Waitrose Food Illustrated, writes: “While those in the food world and others who know and care about the plight of depleting fish stocks have been talking about this for ages, sometimes you need to get something onto the telly to get people to pay attention.”
Whole Story, the Whole Foods Market blog, has a review by Carrie Brownstein, which has generated some debate amongst readers. She says: The film begins with beautiful footage of marine life and quickly (and graphically) moves toward its key message: The oceans are overfished and fish populations are in trouble.”
John Mitchell, writing in the California Chronicle, considers the the social implications of the need to curb overfishing:
“One of the most fascinating passages of the film . . . takes a look at the coast of Africa, which is being overfished by foreign - specifically European - boats. This has decimated not only the sea but also the livelihood of local fishermen, who now have nothing to catch.
“Colonialism is dead officially, but its ghost continues forward in the form of sucking up resources - the fish depletion is a direct contributor to the current pirate problem that’s making the headlines, pushing once-working fishermen into a life of crime in retaliation.”
What saddened Amanda Rappak the most, in the Green Living blog, was the inability of governments to “penetrate the complex fish market system with effective enough controls that would actually limit how much fish is caught”.
She also highlighted the film’s positive message: “The film offers avenues for taking action with its campaign, and so does Greenpeace. But it seems the first step to change would begin with a personal pledge to always knowing exactly where your food comes from and how it reached your plate.”
The Enviro blog at Huck Magazine cites the support the film is getting: “The film which was selected for the Sundance Film Festival this year has gathered international support from organisations such as WWF, and well known faces such as broadcaster Hugh Fearnley-Whittingstall, also offers simple solutions we can all adapt to help prevent such a tragic future.”
Writing in the 1Click2Fame blog, Annabel Harrison says: “After watching the film, I realised that we should be doing so much more to protect what is one of the biggest natural sources of food for humans. The positive aspect of this global issue is that it’s not too late – there is plenty we can do to make sure that species don’t become extinct.”
On her blog, Regency Life in the 21st Century, Kimba writes : “We forget that these waters are also our to maintain, protect, and sustain. How? By eating only sustainable seafood. By helping politicians understand there needs to be protected areas where fishing is illegal. By getting the word out! There is a great new book and film “The End of the Line” that will tell you more.”
Hugh Fearnley-Whittingstall, writer, broadcaster, campaigner and advocate of seasonal and ethically-produced food has offered his support for The End of the Line.

With co-author Nick Fisher, he wrote The River Cottage Fish Book. Hugh says the aim of the book was “to empower you, the consumer, to make choices which will genuinely help to reverse the decline in our native fish stocks.”
He is currently filming for the new series of River Cottage which begins on Wednesday 3rd June on Channel 4.
In the next edition of the River Cottage newsletter, Hugh writes:

Earlier this month, I went to Brussels for a private screening of our film, The End of the Line, and debated the sad state of Europe’s fisheries with Joe Borg, the Commissioner for Maritime Affairs and Fisheries.
Charles Clover, Tony Long of WWF and Joe Borg, Commissioner for Maritime Affairs and Fisheries, debate Europe’s fisheries policy after a WWF screening of The End of the Line
The screening had been organised by WWF for members of the European Commission and country representatives ahead of the publication of the Green Paper on the reform of Europe’s fisheries policy last week.
I was surprised and impressed by two things. First, the openness and dedication with which Commissioner Borg trotted along and watched an 82-minute film and debated its conclusions, especially since these are even more damning about Europe’s management of its fish stocks than the Commission’s own Green Paper – which admits that 90 per cent of Europe’s fish stocks are overfished.
Continue reading ‘Nice reforms Mr Borg, but aren’t you missing something?’
Europe’s fishing policy has failed and nearly nine tenths of its fish stocks are overfished, the European Commission has admitted.
The Commission published a Green Paper proposing radical reforms of the Common Fisheries Policy (CFP) and began an open debate on the proposed measures which will last until the end of this year.
Among the proposals are:
- A ban on the “discarding” of under-sized and unmarketable fish at sea.
- Making the ecological sustainability of fish stocks the paramount objective of European policy, on which economic viability depends, rather than a factor to be weighed off against the survival of the fishing industry, as it is at present.
- Devolving decisions on the management of fisheries closer to the people they affect.

With concern over bluefin tuna stocks growing among environmental groups, we round up the latest news at the start of the Mediterranean bluefin tuna fishing season.
A large tuna is caught by fishermen
Reuters report that a new WWF report says overfishing is set to wipe out bluefin tuna in three years.
The news agency says: “Overfishing will wipe out the breeding population of Atlantic bluefin tuna, one of the ocean’s largest and fastest predators, in three years unless catches are dramatically reduced, conservation group WWF said.
“As European fishing fleets prepare to begin the two-month Mediterranean fishing season, WWF said its analysis showed the bluefin tuna that spawn - those aged four years and older - will have disappeared by 2012 at current rates.”
Sergi Tudela, head of fisheries at WWF Mediterranean, said: “For years people have been asking when the collapse of this fishery will happen, and now we have the answer.” Continue reading ‘Bluefin tuna fishing season starts in the Mediterranean’
What were thought of as certainties can fall apart in the light of new circumstances, new thinking.
For years we have been told that the Omega 3 fatty acids from oily fish such as salmon, tuna and mackerel are good for the heart and brain.
Now, some of the people who proved that the world’s fish catches were not rising but falling - a critical milestone in this century’s thinking - have produced a report that shows that the evidence for the beneficial effects of Omega 3s is somewhat less impressive than one might think.
The study actively challenges dietary advice that we actually should be eating more oily fish.
It says that people in the Northern hemisphere who eat a balanced diet may be getting enough Omega 3s anyway but people in the Southern hemisphere are having their essential proteins and fish oils stolen from them by diet faddism in the North.
Oily fish can actually be bad for overweight or unhealthy people with heart problems, it says.
Was the fad for Omega 3s perhaps just a marketing strategy worked up by the fishing industry? That’s going too far, but it certainly looks as this dietary obsession is something we should be looking at a whole lot more critically now we know that wild fish stocks are in trouble almost everywhere.
Policies can be skewed by vested interests - including our own perceived health interests.
In fact what the human race needs are balanced policies that promote healthy people and healthy wild fish populations, able to feed a human population that will rise by a third over the next half century.
That is what we should be planning for, together with ways of producing Omega 3 fatty acids from vegetables and algae, to take the pressure off fish.
In the meantime, we may actually need to eat less of certain fish - salmon and tuna for instance - rather than more as the dieticians have been calling for.
Scientists have published the first study that casts doubt on some of the health benefits of fish oils - and say that daily doses may actually increase the risk for people already suffering heart disease.

Charles Clover: Omega 3 from oily fish health benefits - the totem wobbles
Omega 3 fatty acids contained in oily fish such as salmon and tuna have long been hailed a “super food” which plays a key role in boosting our immune system, staving off heart attacks and cancer as well as increasing brain power.
Tuna are rich in Omega 3 fatty acids, but are also under threat from overfishing
But the latest study finds little evidence to support the more extravagant claims and experts discovered that angina sufferers may put themselves at higher risk by taking fish oils.
The authors say that people in developed countries already have access to plenty of Omega 3 fatty acids in their diet, while people in poor countries were being deprived of essential oils and proteins by foreign fishing fleets.

Nearly half of all fish produced for food is now farmed rather than caught in the wild, a new UN report reveals.
The biennial State of World Fisheries and Aquaculture (Sofia) report shows that stocks continue to be depleted by overfishing
The amount of fish produced by farming rose in the past two years while the number of wild fish stocks ranked as over-fished, depleted or fully exploited increased to 80 per cent of the world’s stocks.
The figures released in Rome by the United Nations Food and Agriculture Organisation (FAO) indicate that the amount of fish caught at sea has reached a plateau and may be in decline when suspected over-reporting by China is taken into account.
On the other hand, the amount of fish raised by aquaculture rose to 47 per cent of all produced for food. Continue reading ‘Farmed fish set to overtake wild caught fish for first time’
EU: sharks now need protection from overfishing from The Times
It could spell the end of rock salmon or huss being sold at the chip shop. The European Commission, presenting its first plan to limit all types of shark fishing, has said that it had to act to stop several types of shark being pushed towards extinction. Read more . . .

The overfishing of the oceans is contributing to global warming, scientists have found.
They have discovered that the ocean’s ability to absorb pollution and purify the atmosphere is influenced by an unexpected factor – fish droppings.
Alkaline chemicals such as calcium carbonate from fish poo can help balance this acid and help to take carbon dioxide out of the atmosphere
The increase in carbon dioxide in the atmosphere not only drives global warming, but also raises the amount of CO2 dissolved in ocean water, resulting in the sea becoming more acid and potentially a threat to sea life.
Alkaline chemicals such as calcium carbonate can help balance this acid and help to take carbon dioxide out of the atmosphere.
Scientists previously thought the main source for this balancing chemical was the shells of marine plankton, but they were puzzled by the unexpected quantities of carbonate in the top levels of the water.
