For decades, the “Galicia” octopus has been the greatest guarantee of quality. The United Kingdom wants to take it away

The Galician octopus may be the most famous, but for some time now, talking about the most precious cephalopod in the country’s gastronomy requires looking beyond the Rías Baixas. In fact, it forces us to take a leap of hundreds of kilometers and look at the other side of the English Channel, on the southern coast of the United Kingdom. There the English fishermen have encountered a curious octopus invasion which at first they viewed with suspicion (they have been dedicated to capturing other species for generations), but each time it awakens greater interest in London. The question is how can it affect that to Galicia, a land that has turned octopus into a ‘religion’ (in addition to a big business) and that in recent years has encountered the opposite panorama: a fall in the capture of cephalopods. What has happened? That the octopus map is changing. And although we still don’t know for sure how deep (and stable) that transformation will be, it has been clear enough to generate expectation in Galicia, a land closely linked to the cephalopod from a cultural and economic point of view. To understand it, we have to go back to 2025, when fishermen who fish on the southern coasts of the United Kingdom encountered an unexpected picture: in the pots that have been installed for generations to hunt crabs and lobsters, they began to appear empty shells…a clue to the presence of octopuses. Click on the image to go to the tweet. Why is it so strange? Because the ports in the north of the peninsula are used to large unloadings of octopus, but things change when we talk about Newlyn or Brixham, in England. There the boats that go out to fish hope to collect sole, turbot, crabs or lobsters. A few months ago, however, the fishermen encountered an unexpected (and apparently inexplicable) invasion of Octopus vulgariscephalopods that usually live in the Mediterranean or other areas of the Atlantic, such as the Galician coast. It was not a one-off boom. Nor something anecdotal. The phenomenon was so surprising that it even caught the attention of Stephen Castle, a reporter for The New York Timeswho in September traveled to Brixham to talk to sailors and operators. In a chronicle about what he saw there, he talks about fishermen ecstatic to see how their turnover skyrocketed thanks to new catches, auctions of tons of merchandise and veterans of the sector recognizing that it was the first time they had captured the species in their waters in more than 40 years. This is good news, right? Depends. Castle chatted with fishermen who rub their hands when they see the tentacles wriggling in their nets, but also with others who frustratedly tell how octopuses boycott the pots with which they capture shellfish. They are not the only ones who are not enthusiastic about the new plague. “I recently visited the fishing industry in Plummouth and was informed that there was an unusual abundance of octopuses in the south west. The Ministry of Environment and Food understands that the proliferation is affecting shellfish pot fishing and causing concern in the fishing sector in the area,” warned in May last year the Labor MP Daniel Zeichner. And why not take advantage of it? That is the question that the British authorities seem to have asked themselves, who have decided that the cephalopod invasion may be something more: an opportunity. At the beginning of the year Vigo Lighthouse revealed who in London want to promote a formal, regulated and industrial fishery of the octopus vulgaris. In short: make a virtue of necessity and equip yourself with a strategy to gain a foothold in a market that moves billions of euros. Proof that the United Kingdom they are very serious with the octopus is that the Marine Biological Association (MBA) and the Marine Management Organization (MMO), two departments linked to the Government, “are considering how best to collaborate with the EU to learn from existing octopus fisheries.” a few days ago The Voice of Galicia even reported that the country is already looking at the markets of the rest of Europe and Morocco. It makes sense if we take into account that the change on the English coast, with an octopus boom that in turn reduces the population of other traditional species, already affected to the Christmas campaign. Do they have that many octopuses? Yes. In September, after speaking with the manager of a market, Castle talked about the sale of up to 48 tons of octopus in a single day. Official MMO data shows that last year a total of about 1,900 tons of octopus, especially in Brixham and Dartmouth. It is an exceptional fact. First, because it exponentially multiplies the discrete cephalopod capture data recorded so far. Second, because it surpasses the 1,200 t handled in the markets of Galicia. There is sources which indicate that total sales in the UK markets would be much higher. Data from the Xunta on the sale (blue) and price (yellow) of octopus in the markets of Galicia. Is it something new? Yes. And no. It is not the first time that English fishermen have found octopuses wrapped in their nets and pots. Vigo Lighthouse remember that in Devon and Cornwall sailors already encountered similar situations in the late 19th and mid-20th centuries, when the regional press came to speak of “a perfect plague” of “disgusting beasts” that “almost ruined” the sector. On this occasion there are signs that suggest that it will not be something temporary. Experts such as Seteve Simpson, from the University of Bristol, slide that climate change is “a likely factor” in explaining the increase in octopuses in southern England. “Our waters are warming, so our little island of Britain is becoming increasingly favorable for octopus populations,” he theorizes. There are clues that suggest he is not wrong. In Plymouth there are fishermen who recognize that they not only encounter adult specimens when fishing. They also see … Read more

ban octopus farms worldwide

On February 25, Mexico presented a reform of federal law of fishing to prohibit cephalopod farms throughout the national territory. It may seem strange, but when Maki Esther Ortiz Dominguez stood in front of the Senate of the Republic and defended the moratorium on aquaculture farming of octopuses, squid and cuttlefish, what she said made sense. Not only is it that they are a terribly difficult business, it is that there is more than firm evidence (always according to the senator) about the enormous problems of cannibalism and risks to public health that these farms bring. So much so that Mexico is not alone. Chili approved a similar ban in October 2025 and seven US states also have it. And it’s curious because what is being banned, in reality, doesn’t even exist on a commercial scale. The world (also Spain) is trying to prohibit something that is not being done. Which does not mean that it is not being tried. In fact, the Mexican initiative to prohibit “the reproduction, pre-fattening and fattening of cephalopods” in captivity is based on data from the Sisal facilities (Yucatán)the only farm of this type that is operational on the entire American continent. There, with the collaboration of UNAM, they have been trying to make octopus fish farms viable for 12 years. AND the data is terrible: mortality rates higher than 52%, 30% of deaths attributable to cannibalism, extremely inefficient conversion rates (three kilos of fish are needed to produce one kilo of octopus) and systematic mistreatment of these species that, if that were not enough, are considered especially intelligent. Especially intelligent? And ‘sentient’: in recent years, there has been no shortage of statements on the subject (Cambridge, 2012 and New York, 2024); but there is also extensive bibliographical reviews which point out that when we talk about cephalopods, we are talking about animals that are cognitively much closer to us. And that, of course, has generated consequences. In the same way as the publication of ‘Animal Liberation‘ contributed to creating the animal rights movement, all this research on octopuses has led to an unprecedented legislative trend. “Unprecedented” because, perhaps for the first time, the legislation comes before farms are a reality beyond experimental centers. And it’s coming very quickly: this regulatory wave has come together in a couple of years. And who would want farmed octopus? The simple answer is everyone. If the resulting problems are not made visible and affordable cephalopods are available, everyone will eat farmed octopus in a few years. Above all, because they are running out. At least in Spain, there is a whole combination of factors that They have made the octopus migrate north. In Spain, in fact, a proposal in this regard was already presented in the summer of 2025 and the European Parliament discussed the issue in December of the same year. It’s a matter of time, it seems. And, for now, Mexico and Chile are in the lead. Image | Milada Vigerova In Xataka | England is experiencing an unprecedented invasion. The problem is that they are octopuses, and they are devouring everything they can find.

England is living an unprecedented invasion. The problem is that they are octopus, and everything they find are devoured

It was at the beginning of 2025 when science gave With something “more” About those creatures that have given so much to speak. We knew that the octopuses were intelligent, but not to the point of having A “brain” on each arm that allows them, apparently, to act with extreme precision and independently. With such a versatile “beast”, the United Kingdom has been found. But not a normal one, a unprecedented invasion. Attack on the English coast. Yes, the southern coast of England has lived an unusual phenomenon: the massive arrival Mediterranean, a rare species in those waters and, suddenly, has become the protagonist of the docks and fishing markets. In Brixham, the main port of the Southwest, fishermen like Arthur Dewhirc up to 10,000 extra pounds Weekly. Between January and August they auctioned More than 12,000 tonswith daily peaks of 48 tons, which made the town the “octopus capital” of the United Kingdom. Restaurants and shops joined the fury, incorporating the animal of menus and facades, and making it local emblem of an exceptional year. Climate change. Scientists point out TO THE SEA WARMING as the main explanation of the phenomenon. Professor Steve Simpson, from the University of Bristol, underlined In the New York Times that the British waters are at the northern limit of the usual range of the Mediterranean octopus, but the increase in temperatures has made the environment It is more favorable For your settlement. What seemed impossible a few decades ago has now materialized: a direct pulse of visible climate change in the abundance of a species that previously barely reached those latitudes. Benefits and threats. Although for many drags the boom has meant an unexpected economic relief, for crab and lobster marshal It is more gloomy. The octopus, voracious and intelligent predators, have colonized the nasas used to capture crustaceans, devouring them inside and leaving only empty shells. In locations like salocombe, veteran fishermen like Jon Dornom They related the surprise initial (“hundreds of aliens” in their traps) that soon became anguish when checking how seafood populations collapsed. Of a successful trip with almost three captured tons passed to nasas full of remainswhich threatens the sustainability of your business in the medium term. Uncertain phenomenon. That is known, the last great irruption of octopos in English waters dates back to the fiftieswhen they appeared in mass and disappeared in just one or two years. That historical memory remembers the unpredictable of the phenomenon: no one can ensure if the wave will be repeated or if it has been an isolated episode. For fishermen, this uncertainty is crucialbecause its economic future depends on both the continuity of the boom and the ravages that may have caused in crustacean populations. Social and cultural impact. The emergence of octopus has not only lived in economic terms. In Brixham, the animal has become identity symbol Local: murals in coffee shops, neons in port buildings, viral chef videos showing how to prepare it and innovative dishes that have found good reception among neighbors and tourists. In fact, the creature has gone from exotic rarity to mass consumption product in an environment not accustomed to it. Popular enthusiasm contrasts with fear of those who see traditional species of English fishing, fundamental for the diet and trade of the region. Between bonanza and fear. Thus, the octopus invasion On the southern coast of England it reflects the complex interaction between climate change, fishing economy and marine ecology. While some celebrate the closest to an unexpected mana, others They fear a catastrophe that permanently alters the balances of his underwear. Plus: The experience of the fifties remembers that the octopus can disappear as suddenly as it came, but the Global warming suggests that phenomena of this type should be increasingly frequent. For fishermen, the lesson seems clear: the fate of their tasks no longer depends only on the sea, but on climatic fluctuations and the unpredictable behavior of a cephalopod that has become both salvation and threat.

In Galicia the orcs are hitting sailboats. And there is an unexpected reason why they are there: the octopus

In Galicia, at least in part of the Galicia Litoral, summers begin to be marked by something more than the escapes to the beach, the pilgrims, the arrival of Fodechinchos tourists and (unfortunately) forest fires. On its coasts They usually sneak spontaneous ones that attract more and more looks, both for their spectacular and ‘encounters’ that occasionally leave with the small boats that navigate near the estuaries: the orcs. The summer of 2025 is not an exception. And for now he has already left some discovery amazing. What happened? That in recent days the Galician coast has had peculiar protagonists: orcs. It is nothing new. A few years ago We talked to you Already of their incursions in part of the coast of Spain and Portugal and how sometimes they leave the occasional scare when they run into sailboats or small boats. That does not mean that your presence continues to generate expectation, both among the media (even The Times has echoed of sightings) as among the authorities. In fact they have already forced to mobilize Maritime rescue and the Civil Guard. Where did they see? The Atlantic Orca Working Group (GTOA) includes a tool on-line which allows to follow the latest interactions between ships and orcs. His map shows sightings in the surroundings of the Gulf of Cádiz, the Portuguese coast, part of the Cantabrian and especially on the Galician coast. On Saturday Maritime Rescue confirmed the existence of three different groups in the Galician Atlantic Strip and The regional press has confirmed the presence of specimens in The Baixas Ríasalthough Gtoa has also registered interactions further north. Why is it news? For several reasons. The main one, its ‘encounters’ with sailboats. On Saturday maritime rescue already asked the navigators of the region that extreme surveillance on the Galician Atlantic coast and warned that a sailboat had to be towed to the port and another escorted precisely by the presence of orcs. The Pontevedra Civil Account too He spoke A week ago in X of incidents In Costa da Vela, north of the Cíes Islands, with several sailboats involved, and how one of them ended with damage to the helm shovel. Europa Press assures that as a precaution a regatta and maritime rescue was suspended in charge of these days of remember To the navigators a series of basic guidelines in case of these animals, such as not approaching the bands of the boat or navigating to the coast in search of shallow waters. The normal thing is that the incidents (when there are) do not go beyond blows wave loss of the helm, although there are cases of sailboats that They have ended up anxiety. But … why do they act like this? The phenomenon It is not exclusive of Galicia and has given rise to multiple theories that explain the behavior of these cetaceans. Some point to food scarcity, the possibility that ORCAS consider vessels as competition or even an unexpected effect of pandemic and the break of nautical activities, resumed in recent years. Last year a working group of the International Whaling Commission He raised An explanation Much simpler … and curious: the orcas that ram ships are mostly specimens Young and boring They do it as a game, a fun that would not seek to cause intentional damage to the sailboats or the crews that are on board. “It is more playful than intentional,” summarize Alex Cerbino, from the CBI. If true could be a “temporary” behavior, as already Others have been seen. What exactly do Galicia? That is the other surprise they have left this summer in Galicia. Experts have long known that these animals move chasing the Atlantic red tuna, their favorite delicacy. In fact, the search for food is what explains summer migrations from the Strait of Gibraltar to the north, which in autumn look for deep waters and already in winter return to the narrow area, where they remain until spring, Remember Gtoawhich clarifies in any case that migrations of the Iberian orcs can be “diffuse” and it is not strange that they do not travel in block. Now experts have found out more than helps to understand the incursions of these cetaceans in the Galician estuaries. A recent investigation of the Institute for the Study of Mulas Vigo lighthouse either The voice of Galicia He has concluded that the Iberian Orcs arrive in Rías such as Aruouso in search of something more than atlantic red tuna. They also do it to capture other of their stars dishes, cephalopods. What are you looking for? The same as many Galicians and tourists in summer: in addition to squid, the great food of the gray calderones, the orcs look for a good ration of octopus. “They love it!” assures to Lighthouse Bruno Díaz López, director of the BDRI and Doctor of Ecology. “Thanks to the sightings made in recent years and during the weekend in the Ría de Aruous we have resolved a recurring enigma: the orcs penetrate the estuaries to feed on octopus.” Experts have appreciated “series of long and repeated vertical dives, direction changes, controlled promotions and brief ventilation pauses” that, in their opinion, correspond to the hunting methods used by the cephalopod predators. BDRI experts have even seen Orcas pull nasas for octopuses. In case there were doubts, they have also managed to “visually document specimens emerging with octopus in the mouth.” “This finding explains the repeated entrance of Orcas in the Ría de Arousa in the last three years,” they claim. Is it important? Yes. Although the orcs go behind the tuna, the finding gives us new information about their incursions in Galicia. “Beyond their main prey in the open sea, the orcs take advantage of coastal trophic opportunities linked to octopus in specific periods,” concludes The director of the BDRI, who remembers that the phenomenon does not fit only with the most recent observations, but also with the documentary records. “It agrees with historical testimonies of Aguiño … Read more

We have just discovered that rainfall has wreaked havoc on the Galician octopus

The octopus is an animal of interest in the Galician coast, after all, this animal is used as the main ingredient of one of the most popular dishes of its gastronomy. However the fishing of this cephalopod So singular drag difficulties when satisfying market demand. After the octopus track. Now a new study in which researchers from the Marine Research Institute of the CSIC and Pescanova Biomarine Center have participated, gives us an important clue about stress in the common octopus (Octopus vulgaris). It is a track that It can help us to protect the fisheries of these animals and even improve the treatment they receive in the incipient aquaculture sector. Supply and demand. The Galician octopus of our tables does not usually have its origin in Galicia. We are not talking about The Galician-Leonese dispute For the origin of the octopus To Feirabut of the fact that the fishing of this cephalopod on the Galician coasts does not represent more than a fraction of the total consumption of the country. According to data from Vigo lighthousethe octopus campaign 2023/24 resulted in catches of 1.5 million kg (a notable decrease compared to the previous year); while according to data from the Food consumption report in Spain Of 2023, the octopus consumption (next to that of squid) of Spanish households was some more than 41 million kg. Only in preserves, almost 385,000 kg of octopus were consumed according to the report. Piscifactory octopus? So where does the octopus come from? One of the origins is on the African coastspecifically in the north of the continent. Despite this, world octopus demand implies a huge pressure not only on Galician heshes, but also globally. In this context, cephalopod fishing progresses towards a new border, that of the aquaculture or fish farming octopus. A border wrapped, yes in the controversy. While it is true that this practice could relieve pressure on the heshadows and protect coveted species such as overfishing octopus, there are many The voices That they have Raised against The latest projects that point in this direction. The reason: the ethical dilemma to raise for consumption animals whose intelligence It is usually equated with that of some of the most intelligent vertebrate animals such as cats or crows. Octopus stress. It is not to be surprised therefore the scientific interest in understanding aspects such as stress in these animals. Interest reflected in studies such as The recently published In the magazine Physiology-Endocrinology and Metabolism. This analysis focused on stress response mechanisms and potential osmoregulation in the common octopus. The responsible team resorted to liquid chromatography and mass spectrometry techniques, which allowed it to contrast that these animals do not produce cortisol, corticosterone or cortisone, three hormones that we usually associate precisely with response to stress and osmoregulation in vertebrate animals. An unexpected effect. He Team details that their findings can explain the mass death of octopus on the Galician coast seen in times of heavy rains. A phenomenon that It also extends To other geographical contexts. As they point out, rapid falls in salinity caused by rains could jeopardize the “physiological stability” of animals, a direct consequence of not having mechanisms for response to external stress factors such as cortisol. Pondering pros and cons. Learning about this fascinating animal not only allows us to satisfy the curiosity that these creatures generate, it can also help us protect them. It can also help those who seek ways to raise these animals in captivity since we can now intuit that the difficulties in responding to stress may be behind the difficulties that this form of aquaculture poses. It can also help us explain the growing difficulty in fishing these animals, a difficulty reflected in the fall in the volume of catches.

Octopus tentacles have their own “brain.” We are now learning the implications

Octopuses are invertebrate animals, but the absence of a central nervous system like that of birds or mammals does not make their brains less interesting than the rest. Brains, emphasizing the plural since neuronal systems of each of its extremities They have a degree of independence, which leads many to consider them as such. A nervous system not at all central. Now, a group of researchers has studied the nervous systems of these cephalopods to better understand how these nine neural organs operate together and to what extent they maintain their independence. What they observed is that each of these brains had the ability to operate individually. The team responsible for the new study believes that it is thanks to the unique segmentation of the nervous system of octopuses that these animals achieve the level of skill in the management of extremely flexible organs that serve these animals to move, feed, sense their environment, and even copulate. “If you are going to have a nervous system that is going to control such dynamic movement, that is a good way to organize it,” explained in a press release Clifton Ragsdale, co-author of the study. “We think it’s a feature that evolved specifically in soft-bodied cephalopods with suction cups to carry out these worm-like movements.” Studying segmentation. The new study focused on segmentation of this curious neuronal system, analyzing the distribution and function of the neurons of these tentacles, taking as reference an octopus of the species Octopus bimaculatus. Neurons that together add up to a greater number than the neurons located in the “central brain” of the animal, which is responsible for coordinating actions that require the use of various arms. These neurons in the extremities are concentrated, explains the teaminto an axial nerve cord (ANC), which “snakes” the tentacle connected to each of the animal’s suction cups. Neural columns. The ANC analysis showed that neurons in the octopus’s limbs were grouped into “columns” that in turn formed segments that the team compared to corrugated pipes. The segments were in turn separated by gaps called “septa” from which nerves and blood vessels made their way to the muscles of the limb. “From a modeling perspective, the best way to organize a control system for this long and flexible arm would be to divide it into segments,” Cassady Olson added.co-author of the study. “There must be some kind of communication between the segments, which you can imagine attenuates their movements.” Job details can be found in an article published in the magazine Nature Communications. Much to investigate. The tentacles of octopuses are very versatile limbs that allow this animal to navigate the seabed, but also, through their suction cups, they allow these octopods to perceive the world around them, hunt and feed on their prey. Knowing the details of the functioning of such complex limbs will still require new research.
