I don't buy it Mac. The last thing I would think is that the upper classes are stupid. And when it comes to tightwadding they leave Scotsmen gasping in their wake.

They are buying things they value when they go into their bodies. Don't kid yourself about that just to make a political point. And don't kid yourself about Glyndebourne and the Royal enclosure at Ascot. The deals are done in places like that. The smear Brown deals at the moment.

The End of the Line Documentary, which aired for the first time on June 8, 2009, promises to expose the vast environmental damage done by over fishing and is touted as An Inconvenient Truth for Fish, a reference to Al Gore's award winning environmental study on global warming, An Inconvenient Truth.
The End of the Line shows how a culture of excess has contributed to the rapid decline of fish stocks worldwide. It even singles out celebrity chefs and high end restaurants as part of the problem. The opening scene alludes to the issue of trendy foods and how something that seems so small can impact the planet as a whole.

@JTT,
Part of the environmental disaster that the Gulf crude oil spill represents is the further killing off of bluefin tuna. Bluefin have been reduced to less than 10% of their pre "sushi" numbers and now, their major breeding grounds are in jeopardy. The inner Guld of Mexico is one of the Altlantic Bluefins biggest spawn gerounds and this is spawning season.

Fish, next to insects, are the most racially discriminated against creatures on the earth.

This gulf oil spill to the sea life is like a can of raid to insects.

@RexRed,
Several countries have petitioned to have the Bluefin Tuna placed on the CITES list (endangered species). The Atlantic population breed right in the area of the oil spill and the stocks were already down by about 70%. Maybe there will be a natural barrier for keeping fishing out of the Gulf by environmental consequences of the oil spill.

I remember several years ago, someone on a2k said that there is no reason to limit fishing: just raise the price of fish and people will stop eating it.

Right! Make it a luxury item and the chichi of the world will seek it out and eat more and more. Magazines will publish pictures of the likes of Paris Hilton eating it.

Has there been any serious consideration given to such a course of action that you're aware of, farmer?
Most of what I've read so far has been about the dire financial consequences for the fishing industry & local communities in the area.

Why anti-whaling campaigners are the bluefin tuna's last hope

Posted by Wietse van der Werf Friday 18 June 2010 14.04 BST guardian.co.uk

Yesterday we freed several hundred illegally caught bluefin tuna, just a week after our ship the Steve Irwin left Malta.

Having recently returned from an eventful anti-whaling campaign in Antarctic waters, I've discovered the Mediterranean brings different challenges. The engine room has turned into a sauna and sleeping is hard with the soaring heat radiating through the deck above. We are in one of the most overfished seas in the world and have been patrolling the area south of Malta for illegal fishing operations.

In summer the waters of the Mediterranean are calm and warm. Warming up from the east, once the temperature near the surface reaches over 20C, it is an ideal spot for bluefin tuna populations to spawn. The bluefin tuna is a highly prized fish, which finds its way into the Asian markets as a sushi delicacy. But this increasing demand for the fish has taken its toll on the Mediterranean populations, of which 85% has disappeared in the last 50 years.

Day and night we encounter fishing vessels. Our radar is dotted with targets but until yesterday all of the French, Italian and Tunisian vessels we have come across had fishing permits and were frequently escorted by French or Maltese patrol ships. It is no surprise they don't take chances, with both Sea Shepherd and Greenpeace currently active in the area.

With European navy and coastguard vessels patrolling the waters around Malta and in the Tyrrhenian Sea, we decided to enter Libyan waters, an area known for illegal and unregulated fishing. The country claimed a 62 mile fishing zone off its coast in 2005 and has since stopped any independent observers or patrol vessels from entering. Inspectors from the International Commission for the Conservation of Atlantic Tunas (ICCAT), which manages the bluefin tuna fishery, have been hindered from doing their work.

Illegal fishing is believed to be widespread in the area, with one important bluefin tuna spawning area in the Libyan zone of the Gulf of Syrte attracting many fishermen. Greenpeace planned to head into Libyan waters a couple of years ago, but shelved the plan. While neither the EU, nor other Mediterranean countries acknowledge Libya's new fishing zone claim, no nation has dared to enter the disputed waters.


The situation is getting desperate for a fish that is set on a course towards extinction in the near future. In recent years, many attempts to give bluefin tuna added protection through the conventional political processes have failed. In this light, the willingness to directly intervene against illegal fishermen in this most lucrative type of fishing operations might be one of the last chances to get attention for the issue and get the species better protection to ensure its survival.

While the atmosphere on the ship is good, there is a slight hint of nervousness, not knowing what lies ahead. We all realise we are in the waters of a country which has facilitated illegal fishing for many years and might not back down from using force to hinder us. However, our crew is defiant and ready to take the risks necessary to see the mission through. As the US senator and environmentalist Gaylord Nelson once said: "The ultimate test of man's conscience may be his willingness to sacrifice something today for future generations whose words of thanks will not be heard".

Just saw this.

Not a vegan at all, Farmer, not in the least. And I didn't do it to allow me "to state that the market driven wild seafood is ok". The problems that are there for the oceans are not solely the fault of "others".

I'm just tired of you wildly pointing your finger at all the world but not owning up to the terrible waste inflicted upon the world by you and your own. You can seem so academic and honest and then in the next breath a Gunga or an Ican.

Appetite for Destruction

shrimp farming

by Dr Mike Shanahan

The Ecologist magazine, March 22, 2003



Shrimp has always been associated with the small and the puny. Why then is this seemingly harmless crustacean inspiring angry protests throughout the developing world, and why have so many people died as a result? Dr Mike Shanahan investigates.

Susan, a middle-aged cashier in a London high street bank, has developed a penchant for prawns. Ten years ago tiger prawns (also called shrimp) were beyond her budget a rare treat reserved for birthdays and other celebrations. Nowadays, she finds them more affordable and consumes them with gusto at every given opportunity. In contrast, Sri Lankan fisherman Anil caught enough fish to sell and feed his family a decade ago. Today, he struggles to fill his nets and often goes to bed hungry. His eight-year-old son regularly misses school to help his mother find drinking water or his father catch fish. Although the lives of Susan and Anil could hardly be more different they are, of course, closely linked.

Shrimp: crustacean of devastation Last year diners in the industrialised nations of Europe, North America and Japan peeled, chewed and dribbled their way through over a million tonnes of farmed shrimps worth over $7 billion. Shrimp, it would seem, is manna from heaven. It's abundant, protein-rich, eminently tasty and readily adaptable to the full range of the world's cuisines. But, as new research by the Environmental Justice Foundation reveals, the true costs of consuming shrimp are dangerously high.

Shrimp has traditionally been trawled from the ocean in arguably the most inefficient fisheries practice on the planet. The effect of trawl nets on ecological communities on the ocean floor is the underwater equivalent of clear-cutting forests. Although shrimp trawlers provide only 2 per cent of the world's seafood, they haul in a third of all the global fishing industry's 'by-catch'. In that by-catch over 400 marine species have been identified. Nonetheless it is all discarded most of it dead because of its low economic value relative to that of shrimp. In some shrimp fisheries, by-catch levels of up to 20kg for every 1kg of shrimp have been recorded. The species affected include rare turtles, 150,000 of which are estimated to be caught as by-catch annually.

To the uninitiated, the concept of farming shrimp might be quite idyllic perhaps conjuring images of rosy-cheeked, straw-sucking pastoralists leaning over fences to watch their shell-bound charges grow until sufficiently sized to take to market. The reality is less bucolic. In fact, shrimp farming is more of an industrial than an agricultural phenomenon. Having been responsible for widespread clearance of productive land and mangrove forests, shrimp farming is also heavily reliant upon the use of water pumps, aerators and chemical inputs of pesticides, disinfectants, steroid hormones and antibiotics including chemicals banned for use in food production by the EU and US. Many of these chemicals are hazardous to human health. The wider environment is also threatened by the release of effluent from shrimp farms into surrounding waters.

The effects of shrimp farming can be swift and devastating for coastal communities. Livelihoods that have sustained communities for generations have been disrupted, and human rights abuses widespread. As a result, a brutal struggle is being waged on the coasts of some of the world's poorest countries, with grassroots campaigners lining up against the giant shrimp- farming industry.

Dying for our dinner? In April 2002, father of four Sebastião Marques de Souza became the latest casualty in this struggle. Sebastião was a community activist protesting the expansion of shrimp farms into the mangrove forests of Brazil. One night, two men alleged by local campaigners to be connected to the country's burgeoning shrimp-farming industry approached him under the pretence of needing to buy some petrol. They shot him dead.

Worldwide, opponents of the industry claim that shrimp farming destroys lives and livelihoods of coastal communities and that it causes significant environmental damage. Worldwide, those who have voiced opposition to the industry have been threatened, intimidated, beaten or silenced for good by bullets, bombs and machete blades. People have been murdered in at least 11 countries.

In Honduras, murders in the mangroves are no longer a cause of surprise 12 small-scale fishermen have been killed in as many years. Jorge Varela, director of a local human rights and environmentalist group who has himself received death threats on numerous occasions, has said: 'With the complicity of our government, we have given away our people's patrimony to a few national and foreign individuals, and we have deprived thousands of persons of their livelihoods. We have turned the blood of our people into an appetiser.' These sentiments are common to poor, vulnerable and often landless communities that have risen up in protest at the way shrimp farms have blocked access to the coast, reduced local fish catches, and destroyed mangrove forests that for generations have supplied food, medicines, fuel and building materials.

It is not only fishing communities that have an axe to grind about the impacts of shrimp farming. Rice and cattle farmers have found their land rendered infertile and their livestock prone to disease because of the infiltration of salt water pumped in and out of shrimp ponds. In Bangladesh farmland has been seized by force or deliberately polluted to ensure its cheap sale to shrimp-farm owners. The country's coast has become a hot spot of violence and intimidation. Local advocacy group Nijera Kori estimates that over 150 people have died in incidents directly related to the industry's expansion. Frequently implicated in these murders are Bangladesh's 'musclemen' hired enforcers paid by shrimp farmers to protect their interests and further their ambitions. At demonstrations clashes have occurred between landless protestors and police or these musclemen. Shrimp-farm guards have caught and beaten to death innocent people wrongly suspected of coming to steal shrimp. Witnesses in legal cases linked to the industry have been murdered.

Profits for shrimp-farm owners can be spectacular, and such is the avarice associated with the industry that the practice of intimidating or eliminating opponents has become widespread. A culture of impunity is typical of the major shrimp-farming countries, which are characterised by corruption, cronyism and gross inequity. The widespread lack of organisational and economic equality between the industry and the communities opposing it means that while the latter often have no recourse to the law, the former often has little to fear from it.

In many countries, politicians and military figures either have vested interests in, or own, shrimp farms. It is less surprising, then, that army or police personnel have been used to violently suppress protests or to seize land on which to build shrimp ponds. A peaceful protest against illegal land seizures by shrimp farmers in Bangladesh was brutally quelled when police personnel opened fire. Four people were killed including Peasant Women's Association leader Zaheda Begum and 250 were wounded.

Profit and loss in a culture of corruption The farming of marine species was initially promoted as a 'blue revolution', supposedly capable of producing large volumes of food without impacting marine stocks, and thereby increasing availability of food for the hungry. International finance institutions like the World Bank and the Asian Development Bank have actively endorsed shrimp farming as a means of speeding development and alleviating poverty in the developing countries where most shrimp farming occurs. However, while some players in the industry have made vast profits, the external costs are not borne by those who reap the benefits. Rather, these costs are displaced onto some of the poorest and most vulnerable communities. Furthermore, the financial benefits of shrimp production often fail to trickle down to these communities. As land has been seized or rendered unusable, hundreds of thousands of rural poor have been displaced often to cities or to other countries. 'If the mangroves disappear, we shall eat garbage in the outskirts of the city; we shall become prostitutes,' said one traditional shellfish collector in Ecuador, where a single hectare of mangrove forest can provide food and livelihoods for 10 families. By contrast, an Ecuadorian shrimp farm of 110 hectares employs just six people during the preparation of shrimp and a further five during the harvest. Likewise, in Sri Lanka's Puttlam district nearly 20,000 lagoon fishers have been obliged to move to the city in search of work as shrimp farming has wiped out their traditional livelihoods. Civil society groups have reported Sri Lankan refugees citing the spread of shrimp farming as a factor contributing to their flight to the UK. Anil the fisherman and Susan the bank clerk may yet meet.

For those who do not migrate to cities or overseas, employment must be sought in the very industry that deprived them of their livelihoods in the first place. Shrimp fry are needed to stock the ponds and are harvested directly from the sea. In Bangladesh, women work in the water for eight to 10 hours each day.

Illness is common. Some collect shrimp fry near to the farms, where polluted water causes internal damage and skin diseases. Gloves are not provided and hands begin to rot. Conditions in processing plants also leave much to be desired. Many female workers in Indian shrimp-peeling factories are reportedly held virtual captives by the owners. They may sleep above the processing units, where the inhalation of odours and ammonia refrigerants is unavoidable. Common complaints include skin problems and backache from standing for prolonged periods. Urinary tract infections are linked to inadequate toilet facilities.

Handling ice-cold food for long hours has also been linked to arthritis. In 2000, there were widespread reports of processing plant workers having half their $30 monthly salary deducted to pay for a daily meal of thin watery soup.

In a number of countries the salinisation of water supplies and the reduced availability of food resources associated with shrimp farming forces children to miss school to help find food and water for their families. Children also risk their health by working in the same unsanitary shrimp farm and factory conditions as their elders. Shrimp industry child labour has been reported in Sri Lanka, India, Bangladesh, Thailand, Cambodia, Indonesia, Peru, Ecuador and Burma.

The future Industrial shrimp farming has experienced massive growth since its advent in the 1970s. Shrimp is now farmed in over 50 largely tropical and sub-tropical countries. Today nearly a third of shrimp eaten comes from these farms. Shrimp recently overtook tuna as the top seafood in the US, where an average of 1.9 kg of shrimp is consumed per person per year. The industry's expansion is relentless, and new areas of Africa's coastline are currently being targeted by investors.

Like so many activities that result in resource-use conflict, shrimp farming is destined to continue causing serious social problems. The roll call of martyrs will keep growing unless the industry undergoes radical change. Just as logging and oil exploration have become the focus of international attention following exposure of their human rights and environmental consequences, so there is an urgent need for scrutiny of shrimp farming.

Whether stir-fried, barbecued or curried, our passion for this tender crustacean is undeniable. However, to sate our appetites, communities worldwide are becoming hungrier, thirstier and less empowered to determine their own lives. This is not a model of development of which to be proud.

The late Shri Banke Behary Das was a prominent Indian environmental campaigner. His words, which resonate with passion and poignancy, neatly encapsulate the essence of shrimp farming's negative effects and identify the players most capable of forcing a change us, the consumers. 'I say to those who eat shrimp and only the rich people from industrialised countries eat shrimp I say they are eating the blood, sweat and livelihoods of the poor people of the Third World'.

@JTT,
I can't see why any of that would bother an evolutionist JT.

History and biology is full of mal-adaptions being swept aside. The "survival of the species" is not a cliche. And now psychology is in play.

Cheap food, like cheap gas, releases income for soft furnishings, fashions, extensions and many another item which can be used to look good and satisfy a craving for novelty both of which are not new to the world but they are new to the masses. It's a bit like Malthus. The masses can consume whatever the producers can supply with, it looks like, no limit.

The shallow waters near the shores are like fields at soaking up the sun. Shrimp is an ideal crop. And if sad posts like your's have an effect I feel sure the product can go in soups and animal feed as protein. It's probably impossible to avoid eating shrimp in some form just as I've heard is the case with corn.

Traditional societies are not allowed to stand in the way of progress. Surely that's an iron law of evolution. If you were teaching evolution theory you would have to censor yourself to avoid bringing it to bear on this matter. And that wouldn't do would it when the main argument of the proponents of teaching evolution is to tell the kids the scientific truth. That there are other matters as well of a similar nature is off topic here so I won't mention any of them.

Some of you might be interested in reading this article, which I found on the BBC News site. It's about the serious impact of over-fishing by "pirates" & the effects on marine life & the health of the world's oceans. The author is Karen Sack, director of international ocean conservation at the Pew Environment Group, a US-based global think tank. She also suggests some positive actions to tackle the problem. It's a long article, but well worth a read, I think.:

Hooking the high seas' fishing 'pirates'

VIEWPOINT/BBC


It's time to close the net on fishing "pirates" who threaten to undermine vital marine ecosystems, says Karen Sack. In this week's Green Room, she highlights the scale of the problem of illegal fishing and calls on the international community to act.

http://newsimg.bbc.co.uk/media/images/47887000/jpg/_47887253_fishpa.jpg
Gaps in current international fisheries management and the failure to tackle IUU fishing are undermining the health of marine life in our oceans

Tales of pirates have filled countless books and films for generations.

Today, modern tales of piracy off the coast of East Africa have captured the world's attention.

Yet, there's another form of piracy on the high seas - fish pirates, who are stealing the wealth of life out of the oceans.

And the international community ignores this problem at the peril of the billions of people who depend on healthy marine ecosystems for both food and their livelihoods
.

According to the UN, the total value of world fish exports was US $102bn (£70bn) in 2008 alone.

More than half of all fish caught worldwide is traded internationally, with most being caught in the waters of developing countries or on the high seas but sold to markets in Europe, North America, Japan or China.


As a result of collapsing fish populations, some scientists have estimated that industrial-scale commercial fishing may be a thing of the past by 2048.

Under the radar

Illegal, unreported and unregulated (IUU) or "pirate" fishing is a lucrative practice which compounds the problem of overfishing.

Worth as much as $23.5bn (£16.1bn), IUU fishing takes an estimated 11 to 26 million tonnes of fish from our oceans annually, roughly equivalent to about one-fifth of the global reported total marine fish catch.

Not all nations have the funds or resources to police their waters

But this practice does not take place entirely below the international community's radar. Indeed, in the EU there are documented cases of vessels which have benefitted from public subsidies later being found guilty of fisheries infringements.

Recently, the UN convened a special week-long conference to discuss the state of fisheries management on the high seas.

Included on the agenda was a look at the implementation of the 1995 UN Fish Stocks Agreement and the efforts of Regional Fisheries Management Organisations (RFMOs) to combat the threats facing global fish populations.

In order to focus the attention of world leaders on the threat of IUU fishing, the Pew Environment Group presented the results of a recently published study in the journal Science at the conference.

The research illustrated how gaps in current international fisheries management and the failure to tackle IUU fishing are undermining the health of marine life in our oceans. ...<cont>
