Within the wild, octopods are solitary animals that roam freely within the sea. They spend their days and nights catching prey with their eight arms. With their large eyes, they observe intently what’s happening round them in reefs and on the ocean flooring, tasting with their suction cups and altering the colour of their pores and skin to mix with their atmosphere.
For many individuals, such distinctive traits have made a Spanish firm’s more-than-four-year effort to lift octopods for meals in factory-like situations all of the extra horrific. Within the farm deliberate for building off Spain’s Gran Canaria island, the animals could be stored in small, slender cages stacked atop one another in a multistory industrial constructing. To kill the octopods, they’d be positioned in ice water at minus 3 levels Celsius (27 levels F). In accordance with plans leaked to the BBC, the farm was designed to supply 3,000 metric tons of protein-rich meat from 1 million animals per 12 months.
Nueva Pescanova, the Spanish firm behind what could be the world’s first industrial octopus farm, says it’s addressing a rising demand for pulpo, protein-rich octopus meat, citing business projections that world consumption will enhance by greater than 20 % by 2028, in comparison with right this moment. The corporate additionally claims that octopus farming may assist preserve shares within the wild.
Latest analysis reveals that octopods can plan forward, keep in mind particular person people, and resolve advanced duties.
Animal rights activists from around the globe disagree and are calling for a direct halt to the approval course of. “We should not condemn these extremely delicate animals to such distress,” they wrote in a petition to the Spanish authorities and the European Union parliament.
Thus far, remaining approval has not but been granted for the mission. However the controversy raises far bigger questions: What sort of relationship do people wish to have with octopods, which present the best ranges of invertebrate intelligence on the earth? How intensively ought to we exploit them, both for meals, science, or show, and the way properly are we defending them?
For hundreds of years, people have eaten octopods. However other than their meals worth, the animals had been thought-about so alien that they acquired solely scant consideration, even from science. In Europe, they had been primarily considered monsters, rumored to sink ships. Within the nineteenth century, Victor Hugo wrote, “If there aren’t any limits to the creativeness on the subject of creating one thing hideous, the octopus could be thought-about a masterpiece.” However the extra folks noticed and realized about these creatures in aquariums, the extra their disgust turned to sympathy, even affection.

When in 2016 an octopus known as Inky climbed out of his tank one evening at New Zealand’s Nationwide Aquarium, moved a number of meters throughout the ground, and vanished into the ocean by a protracted and skinny pipe, information of the escape travelled around the globe. Folks had been stunned when Billye, a Pacific large octopus, shortly realized take away screw caps from jars on the Seattle Aquarium. After an octopus in Germany, which had change into well-known by predicting the result of World Cup soccer matches, died, newspapers around the globe eulogized him. And in 2020, the Netflix documentary My Octopus Trainer was watched by hundreds of thousands of viewers.
Latest analysis has revealed that octopods can plan forward, establish and keep in mind people individually, and resolve advanced duties. Final 12 months, scientists from the Okinawa Institute of Science and Expertise confirmed that, identical to people, octopods have two very completely different sleep phases, one deep and one with elevated bodily exercise. Researchers even posit that they will dream. All of that’s fairly exceptional for a creature that lacks a backbone and is extra intently associated to ants, slugs, and worms than to vertebrates.
Biologists know of about 300 species of octopods, inhabiting many alternative components of the ocean, from coastal lagoons to depths of 5,000 meters. Some have an enormous vary, just like the widespread octopus, which could be discovered within the tropics, subtropics, and in temperate waters. Some are extraordinarily uncommon, just like the roughy umbrella octopus, which is understood solely from just a few areas close to New Zealand’s Chatham Islands.
In 2022, the British authorities included octopods within the record of “sentient beings” of its Animal Welfare Act.
Aside from their physique structure, virtually all octopods share a predatory and solitary way of life (social octopods have been noticed in just some small colonies off Australia, Japan, and Nicaragua). All octopods stay for between one and three years, and after hatching their eggs, females die. Regardless of these traits, octopods present indicators of intelligence often attributed solely to hundreds of thousands of years of intensively social existence in mammals. Scientists are nonetheless struggling to know how one thing so short-lived as octopods — which haven’t any likelihood to be taught from mother and father and friends — can carry out its cognitive feats.
When the scientist Nikolaus Rajewsky visited the Monterey Bay Aquarium just a few years in the past, his gaze fell on a darkish, immobile lump with giant eyes. The octopus and he appeared one another within the eye for half an hour. The scientist felt surprisingly moved. “On the one hand, I had this animal with no backbone in entrance of me, a relative of snails,” he recollects, “and on the opposite, there was an actual particular person speaking with me as a human being.”
The encounter left a deep impression. “I usually take into consideration that second,” says Rajewsky, who heads the Berlin Institute for Medical Techniques Biology, the place he research gene regulation and, extra lately, octopus intelligence. In 2022, Rajewsky revealed a paper suggesting that the parallels between mammalian and octopod brains lie of their genetic programming — which is curious, as a result of their final widespread ancestor, a primitive wormlike animal, lived greater than 500 million years in the past. However of their mind cells, cephalopods have mechanisms — known as microRNAs — which can be thought-about a prerequisite for clever conduct in mammals, too.

Such discoveries drive a reasonably younger motion to extend the safety of octopods, from analysis labs to the depths of the oceans. In 2022, the British authorities included octopods within the record of “sentient beings” of its Animal Welfare Act, in accordance them a standing like vertebrates. And in September 2023, the U.S. Nationwide Institutes of Well being requested the general public for enter on new guidelines for a way cephalopods — a gaggle that features nautiluses, squid, and cuttlefish — may very well be handled higher in analysis labs.
This elevated stage of concern is in stark distinction to how octopods are handled in fisheries. Between 350,000 and 500,000 tons of between 20 and 100 completely different species of octopods are caught annually for human consumption, up from about 100,000 tons within the early Seventies, in accordance with the Meals and Agriculture Group (FAO).
Octopods are sometimes taken as bycatch in industrial-scale fishing operations, however they don’t seem to be discarded, resulting from their financial worth. In additional artisanal fisheries, particularly alongside coastlines in Japan, South Korea, Spain, and Portugal, they’re the primary goal. Hunters go after the animals with traps that simulate secure hiding areas. Spears are typically utilized in East Africa. In coastal communities, octopods could be an necessary supply of protein and “a vital useful resource for the livelihoods of weak folks,” in accordance with Sustainable Fisheries, a U.S.-based NGO.
The FAO warns that “world octopus landings have been on a declining pattern for a number of years.”
However specialists are deeply nervous concerning the lack of a global administration system and, in lots of components of the world, coordinated catch restrictions. For whales and for some fish species, monitoring efforts result in strict annual quotas, that are no less than partly enforced. However for octopods, the worldwide business is in lots of circumstances operating blind: they’re harvested with out data of their species or reproductive capability, in accordance with a complete evaluation by a group of scientists led by Warwick Sauer, from Rhodes College in South Africa.
For instance, a examine revealed that in a big a part of the Atlantic, annual catches of the widespread octopus might need been 5 occasions increased than official statistics point out. “World catch information for octopuses needs to be thought-about a really tough estimate of complete harvest, and more likely to be a substantial underestimate,” the FAO warns.
Alongside coastlines, nationwide or regional guidelines might restrict how usually artisanal octopus fishers can exit to sea or set a minimal catch measurement to guard potential offspring. “However guidelines are solely pretty much as good as controls, and in lots of areas these don’t exist,” says Daniel Oesterwind, a marine biologist with the Thünen Institute of Baltic Sea Fisheries in Rostock, Germany, and a member of the Cephalopod Worldwide Advisory Council. Even the E.U., which prides itself as a champion of nature safety, to date has no monitoring and governance system in place for octopods in its widespread fishery coverage.

The FAO warned in late 2023 that “world octopus landings have been on a declining pattern for a number of years.” The IUCN’s Purple Listing data octopods, with just a few exceptions, as both “information poor” or “of least concern,” however with the footnote that inhabitants tendencies are “unknown.”
Oesterwind factors out that projections are hindered by the octopods’ brief lifespan. “They reproduce solely as soon as, which results in sturdy fluctuations, so populations tendencies are troublesome to foretell,” he says. It is a hazard for his or her survival, too: “If one era of spawners is fully eliminated, the inventory will stop to exist.” In some components of the world, efforts are underway to stabilize populations. Fishers in Asturias, in Spain, and in Western Australia have dedicated to following guidelines — concerning the variety of traps utilized by fishermen, the minimal weight of catch, and the fishing interval — for certification as a sustainable fishery by the Marine Stewardship Council.
In different nations, native communities are managing their very own techniques. Within the shallow reefs across the Tanzanian island of Songosongo, for instance, the widespread octopus and huge blue octopus stay in small caves. Villagers have lengthy used spears to convey the animals ashore. Nevertheless, as octopods have more and more been traded and exported, overexploitation has change into a giant downside. To handle this, communities have began to handle the fishery collaboratively.
Elevating octopuses in confined areas will result in “stress, battle, and excessive mortality,” says a researcher.
“You sit collectively, talk about, and discover a answer,” says Modesta Medard, the marine program coordinator at WWF Tanzania. To cease the downward pattern in shares, villages selected a approach that was so simple as it was efficient: they started to shut the reefs for 3 months yearly. “It was a part of the normal data that octopods at all times stay in a house for 3 months, develop up, after which transfer on,” says Medard. The periodic closures, which provides the animals time to breed and develop, proved worthwhile. The common octopus catch has elevated measurably, and with it, native revenue. On the identical time, the reefs and their different inhabitants are higher protected.
Whereas there’s consensus amongst octopus scientists that such tasks ought to get extra assist and be carried out in lots of extra areas, opinions diverge on octopus farming.
Some scientists have joined the protest towards the Nueva Pescanova mission: “Octopods ought to by no means be stored in giant numbers in confined areas. It results in stress, battle, and excessive mortality,” says Jonathan Birch, who researches animal consciousness on the London College of Economics. “It’s apparent that wild octopods lead a significantly better life than [octopods] fattened up in plastic containers to finish up on our plates,” says environmental scientist Jennifer Jacquet, of New York College.

However octopus farms even have advocates within the scientific neighborhood. “Maybe this can assist to higher shield wild octopus populations and create an extra supply of protein for us people,” says Australian marine ecologist Zoë Doubleday. “Octopus are prime candidates for aquaculture due to their excessive charges of development and meals conversion,” Warwick Sauer and colleagues conclude of their complete evaluation of the group. They see the most important problem in acquiring a sustainable synthetic feed that’s formulated from vegetarian sources. In any other case, octopus farming may merely enhance overexploitation of fish shares.
In accordance with studies in Spanish media in late 2023, Nueva Pescanova has but to lift enough funds for its farm and is constant to pursue its mandatory licenses, but it surely has no agency begin date. The corporate didn’t reply to requests for remark.
One main octopus researcher, zoologist Louise Allcock of the College of Galway, thinks that the controversy concerning the Spanish plan requires a broader interrogation. “Pigs are additionally particular animals, they’re among the many most clever creatures, and but we hold them in atrocious situations,” she says. For this reason, in her view, the complete meals manufacturing system must be challenged. The goal, she says, needs to be to “change to a plant-based weight loss plan so far as potential” — and go away sentient, wild animals like octopods alone to roam the ocean.
