I don't eat cephalopods, but I do eat meat. Across the Atlantic, Carlos Rosas has an easier time with the octopus life cycle. FULL TEXT The full text of this article is available. I try to only buy meat and eggs that are organic, grass-fed, cage-free, all that (and there are many classifications). An Italian lab has even invented an octobot that can explore underwater crannies. Also read about the growing trend for pet octopuses. These drawbacks have prevented octopus farms from making progress – until recently. Keeping young animals in water whose salinity and temperature are carefully controlled has also proved tricky. Should people farm octopus? Both highly intelligent and a culinary delicacy, the animals are at the center of a controversy that pits the conservation of wild octopuses against the ethics of mass-breeding them. They say the move is ethically inexcusable and environmentally dangerous, and have called on private companies, academic institutions and governments to block funding for these ventures. In 2019, a handful of scientists started to raise questions about the ethical and ecological issues that might come from farming these remarkably intelligent animals. Big brains, complex behaviour, and precocious curiosity have made these improbable molluscs mediagenic poster creatures for animal rights and welfare—and the subject of an emerging battle over the ethics and potential environmental impacts of raising them for food. If we take the purist view, and the wild population gets threatened or damaged beyond repair, where will we be?”. Is farming them ethical? Ricardo Tur Estrada, Pescanova’s research chief and a veteran of the institute, says it has not only raised successive generations of Octopus vulgaris, the Atlantic common octopus, but also delayed the kill switch on octopus lifespan. (Also read about the growing trend for pet octopuses. There are approximately 300 species of octopuses, more than 100 of whichare captured in the wild using nets, pots, lines, and traps. Aquaculture advocates say that farming octopuses is the only way to ensure sustainability while satisfying demand. Octopus farming ‘unethical, environmentally dangerous’,London, May 12 (IANS) Researchers have said that plans to create octopus farms in coastal waters around the world are ethically inexcusable and environmentally dangerous and called on private companies, academic institutions and governments to block funding for these ventures. But octopuses are also a culinary delicacy. Octopuses are delicacies and do not deserve to be the focus of intensive farming. However, several recent articles have focused on the ethical implications of creating an industry exploiting intelligent, potentially conscious species such as octopus. Since 2008, the reported annual catch of octopuses has been about 350,000 metric tons – but the actual number could be higher because catches are often underreported, particularly in artisanal fisheries. Such sustainable sourcing may be more feasible for experimental and artisanal projects like theirs than for the marine factory farms Jacquet warns against. Joined May 30, 2000 Messages 10,414. Plans to create octopus farms in coastal waters round the world have been denounced by an international group of researchers. For some, octopus farming also raises ethical concerns. Furthermore, Tur says, “we have eliminated the competition and cannibalism” that are octopus hallmarks, and have identified a previously unreported fourth stage in the common octopus’s life cycle—transparent alevin, a transitional stage between paralarvae and fully formed juveniles. Octopus Farming & Ethics. Consider these facts: farmed poultry accounts for 70% of all birds on the planet. There are approximately 300 species of octopuses, more than 100 of which are captured in the wild. The only octoculture effort in the U.S., Kanaloa Octopus Farms, on Hawaii's Big Island, has hit the same “bottleneck,” as founder Jake Conroy calls it. “We're working to reduce the octopuses' sensitivity to pain when we sacrifice them,” he adds—numbing them with cold water, then cutting quickly through their brains. Despite this, around the world, the demand for delicacies made with octopus is on the rise. Most wild octopus fisheries are still more artisanal than industrial, using small boats and traditional techniques. Elephants are falling into trenches on Indian tea plantations, Elephants, glass frogs and mako sharks... vital updates from the world's most important wildlife conservation event, Bats are being killed so people can drink their blood, Hunters target endangered pangolins in India, How one man is working to save one of the world's most poisonous animals. For some, octopus farming also raises ethical concerns. Like salmon, they're short-lived and fast-growing; most common species live one to two years, a few jumbo varieties three to five. He thinks this stage, when the animals learn to use their arms and develop their remarkable color-changing pigmentation, will provide key biological insights. Fisheries Wildlife. Peter Godfrey-Smith of Sydney University, a contributor to the paper, said, “That means campaigners and activists don’t have products or outlets to target. The mollusks are highly intelligent creatures that need environments that are dynamic and stimulating in nature. In “The Case Against Octopus Farming,” Jennifer Jacquet and her co-authors—Becca Franks, of New York University, animal activist Walter Sanchez-Suarez, and Australian science philosopher Peter Godfrey-Smith—cite the general ills of industrial husbandry and aquaculture. The situation is similar for mammals with 60% of them worldwide being livestock, mostly cattle and pigs. Farming them intensively would probably cause large numbers of deaths from stress. Getting to grips with octopus farming’s ethical issues. Is farming them ethical? Rosas and Tur invoke other justifications for farming octopuses: community development and basic research. The main markets for the animals – the US, Europe, Japan and China – are areas where people are already well-fed. As the popularity of eating octopus has grown, efforts to farm them commercially are raising questions about their welfare in captivity. His response has been to enlist local women—wives of octopus fishermen—to clean and maintain his lab's dozens of tanks in exchange for all the marketable octopus produced. Impressed at the results, their husbands and sons have begun joining the co-op. Octopuses are delicacies and do not deserve to be the focus of intensive farming. And, like other carnivorous aquaculture, octopus farming would increase, not alleviate, pressure on wild aquatic animals,” they argue. The main markets for the animals – the US, Europe, Japan and China – are areas where people are already well-fed. Among the million tonnes of molluscs, octopus farming is an emerging issue. Samantha Andrews. “There are ethical concerns over octopus farming,” said Rosas-Vázquez. Getting to grips with octopus farming’s ethical issues. The operation is artisanal. Octopuses at a fish market in Tokyo, Japan. The ethical objections are simple – octopuses are intelligent and mysterious creatures and not enough is known about them to ensure they live a good life in captivity. Octopuses are curious creatures who can suffer from stress. Welfare Husbandry. But the global catch—420,000 metric tons a year, the FAO reports—goes largely to affluent consumers in South Korea, Japan, Spain, Italy, Portugal, and, lately, the United States. Pulpo a la gallega may be the national dish of Spain's Galicia region, but Galicia imports 20 times as much octopus as it catches. Since 2008, the reported annual catch of octopuses has been about 350,000 metric tons – but the actual number could be higher because catches are often underreported, particularly in artisanal fisheries. EXTERNAL STUDY This is a summary of an external study. I would much rather that they survived to do their own thing in the sea. The main markets for the animals – the US, Europe, Japan and China – are areas where people are already well-fed. United Kingdom. As we’ve stated before, decades of scientific evidence have demonstrated that humans have no biological need to consume flesh or other animal products. Conroy, a biologist who turned to aquaculture to escape the research-funding rat race, admits that such close encounters don’t encourage more consumption. The fledgling octopus farming sector should be shut down for both ethical and ecological reasons, according to a number of eminent academics. “The data is for us, the octopuses for you!” Rosas says, joking with two co-op members. 105k members in the nature community. But he faces another challenge: shoestring budgets, typical of Mexican research. Among the million tonnes of molluscs, octopus farming is an emerging issue. “Octopus factory farming is ethically and ecologically unjustified.” Farming octopuses is a really bad idea. Some researchers, however, are pointing to environmental and ethical reasons why octopus farming might not be as simple as it seems. In 2019, a handful of scientists started to raise questions about the ethical and ecological issues that might come from farming these remarkably intelligent animals. “That's not sustainable, that's less unsustainable,” replies Jacquet, adding that even if researchers “reduce other ecological impacts, farming octopus would still be unethical.” It is after all a luxury product, unneeded for food security; banning octoculture would “mean only that affluent consumers will pay more for increasingly scarce, wild octopus.”, That, Conroy says, is why octopus should be farmed: to relieve wild stocks. At the A group of scientists are arguing against the development of octopus farming. During the recent World Octopus Day, an article looked at how octopus farming could become a reality and detailed a study about the ethical concerns surrounding commercial farming. The common octopus, O. vulgaris, is found around the world. But octopuses have largely escaped this … Sheep were probably the first animals domesticated by hu- mans for food, starting at least 9,000 years ago. Some scientists speculate that global octopus populations are booming, but specific wild populations in spots around … In one experiment, scientists observed octopuses building shelters from pieces of coconut shell. As per the most recent research has been published in the Issues in Science and Technology Journal, Researchers have remarked that plans to create 'octopus farms' in coastal waters around the globe are 'ethically inexcusable' and 'environmentally dangerous' and called on private companies, academic institutions and governments to block funding for these ventures. The case against this practice is centred on both ethical and environmental considerations. Contacted in January, Nisui would say only, “Unfortunately we are still in research and development stage.”. There are approximately 300 species of octopuses, more than 100 of which are captured in the wild. A group of scientists argue against ongoing efforts to farm octopuses, highlighting ethical and ecological issues in making their case. A mouse-sized octopus with tentacles like knotted threads, ghostly pale save for big, black eyes, wriggles across his palm and twines around his fingers. In addition to discussing ethical concerns and methods of humane killing, as well as the ecological implications of in-shore intensive aquaculture of cephalopods. There have also been advances in controlling the environments in which octopuses will be raised. Now they’re becoming an ethical flashpoint, as researchers like Rosas puzzle out ways to make commercial octopus farming feasible and, they claim, relieve growing pressure on wild populations. The culture, at least in Mexico, is intended to be on a family scale that allows people to improve their living standards. It predicts a fully-farmed, market-ready octopus by 2020. She will then be two years old, about twice the average O. vulgaris lifespan. “But there is also little awareness of the cultivation systems and those who cultivate octopus. Commercial-scale octopus aquaculture could save wild populations—but is not only extremely difficult, but raises major ethical concerns. In an essay last year, researchers including Jennifer Jacquet, assistant professor of environmental studies at New York University, and Australian philosopher Peter Godfrey-Smith decried its ethical and environmental perils. “There are ethical concerns over octopus farming,” said Rosas-Vázquez. Thousands of fishermen in Mexico's Yucatán and Campeche states lure their prey by dangling crabs from long bamboo poles. The biggest problem has been keeping young octopuses (known as larvae) alive, in part because so little is known about their nutritional needs. A group of scientists are arguing against the development of octopus farming. At a glance, therefore, these tasty tentacle bearers seem ripe for aquaculture. by Samantha Andrews 28 June 2019, at 10:02am With demand rising globally, octopus farming is developing apace – but, mindful of both the animals’ welfare and concerns around sustainability, should we be scaling it up at all? “That means campaigners and activists don’t have products or outlets to target. There are about 300 species of octopus and many behave in surprisingly sophisticated ways. But the case for octopus farming is weak, according to Jacquet and her co-authors. That’s to entirely miss how product development works. As global de- mand for octopus grows, especially in affluent markets, so have efforts to farm them. The world wants to eat more octopus. Add to MyAgriExpo favorites. Octopuses are considered to be one of the smartest creatures in the ocean—and people love them. In the wild, octopuses breed once, then cease hunting and waste away; the females spend their last weeks tending their eggs. The researchers say that farming octopuses would require the catching of vast amounts of fish and shellfish to feed them, putting further pressure on the planet’s already threatened marine livestock. Octopuses are delicacies and do not deserve to be the focus of intensive farming. It is unsustainable. During the recent World Octopus Day, an article looked at how octopus farming could become a reality and detailed a study about the ethical concerns surrounding commercial farming. “We can see no reason why, in the 21st century, a sophisticated, complex animal should become the source of mass-produced food,” Jacquet told the Observer. These efforts have foundered, however, because octopus larvae eat only live food – which has made feeding them difficult and expensive. The group, led by Professor Jennifer Jacquet of New York University, argues that octopuses are highly intelligent, curious creatures. Consider these facts: farmed poultry accounts for 70% of all birds on the planet. From our point of view, farming any kind of animal is an act of cruelty. They can add 5 percent of body weight in a day. Commercial-scale octopus aquaculture could save wild populations—but is not only extremely difficult, but raises major ethical concerns. Animal agriculture is both cruel to individual animals and environmentally unsustainable. Now they’re becoming an ethical flashpoint, as researchers like Rosas puzzle out ways to make commercial octopus farming feasible and, they claim, relieve growing pressure on wild populations. Staff member. London : Researchers have said that plans to create octopus farms in coastal waters around the world are ethically inexcusable and environmentally dangerous and called on … The amount of feed needed to sustain and grow an octpus is three times the weight of the animal itself and, given that octopuses are carnivorous and live on fish oils and protein, rearing them risks putting further pressure on an already over-exploited marine ecoystem. But a concerned team of international researchers write that farming these cephalopods at industrial scales will dramatically intensify the environmental impact of aquaculture--and put us in ethical hot water, too. But a concerned team of international researchers write that farming these cephalopods at industrial scales will dramatically intensify the environmental impact of aquaculture–and put us in ethical hot water, too. According to researchers, there … Other companies, in Mexico and Australia, have also reported that they will be selling their own varieties in the near future. Farming octopus is counterproductive from a perspective of environmental sustainability and misguided from a perspective of humane food production. But that life cycle presents one big hurdle: sustaining delicate planktonic octopus hatchlings, called paralarvae, until they can begin this rocketing growth.
