The Kärcher KHD 3 that we can find at Lidl (the one on Amazon is very similar) is a pressure washer that includes a high pressure gun that allows you to clean from the terrace to the car or certain garden furniture. And the good thing is that it includes a good assortment of accessories. First of all, one of the most useful is the rotating nozzlewhich allows you to adjust the water pressure to adapt it to the surface we want to clean. It also comes with a high-pressure hose that is four meters long for convenient cleaning. On the other hand, it is worth mentioning that the Kärcher KHD 3 offers a power of 1.6 kW and is aimed, above all, at eliminating certain stains that are difficult to remove. It is more for occasional use and not so much for regular use.. In addition, it is also important to note that the pressure washer comes with wheels to be able to transport it more comfortably. ⚡ IN SUMMARY: pressure washer offer ✅ THE BEST The price: Pressure washers usually have much higher prices, so it is appreciated to have much cheaper models.

Tenerife was known for the sun and its beaches. It will soon house one of the five most powerful supercomputers in Spain

by

Tenerife will have a new supercomputer. I already had two with the names of Teide and of Anagaand they will now be joined by a new and promising project called the Atlantic Supercomputing Center. With it, it is hoped to turn the Canary Islands into a new nerve center for retaining and attracting talent in the technological field. Up to 10 million euros of investment. This new project It is a collaboration of the Cabildo of Tenerife and the Institute of Technology and Renewable Energies (ITER) with the German technology giant Bechtle. It will have an initial investment of 5.5 million euros, which could rise to 10 million as its four phases are deployed (two for storage, two for computing) oriented by the demand for the center and its resources. The expansion is flexible and Bechtle will supply the latest technology available at the time of project execution to avoid the use of obsolete components. The fifth supercomputer by power in Spain. By integrating with the existing nodes, the Atlantic Supercomputing Center will achieve a combined power that will place it as the fifth most powerful supercomputer in the entire national territory. It is also expected to enter the prestigious TOP500 list which brings together the most powerful supercomputers from around the world. Hybrid architecture. The rise of AI has meant that the project has an architecture that will allow working with both more conventional workloads and those intended for projects in the field of artificial intelligence. Thus, its architecture will be hybrid: CPU: although it has not been specified which processors it will use, it has been indicated that the supercomputer will have 13 nodes with 288 cores each, which will allow for more than 3,000 process cores to execute scientific tasks, for example. GPU: there will also be four specialized nodes with a total of 32 Nvidia H200 NVL cards, which will allow training of large language models and the development of AI projects. Performance: this expansion is expected to provide between 1.3 and 1.4 PFLOPS of global computing power (close to 300 TFLOPS in CPU and almost one PFLOP in GPU), indicated those responsible for the Cabildo de Tenerife and ITER. Hours instead of months. The president of the Cabildo, Rosa Dávila, stood out that local laboratories, the University of Las Palmas de Gran Canaria and the University of La Laguna among others will be able to access these resources to be able to compute in hours what previously could take months. Juan José Martínez, from ITER, recalled how during the pandemic the Teide-HPC supercomputer It was one of the five centers in all of Spain who sequenced and monitored the biological variants of COVID-19. From the audiovisual sector to the aerospace sector. Among the sectors that will benefit from this computing capacity will be those associated with the audiovisual industry. The Teide-HPC infrastructure was for example used to render scenes from the film ‘Tadeo Jones 2: The Secret of King Midas‘. It will also be the core of the project management of canary satellite constellation. Attracting talent. This facility also wants to become an element that reinforces the role of the Canary Islands as a technological hub. Having a supercomputing infrastructure like this wants to help attract technology companies that promote highly qualified young employment and therefore retain and attract new talent in this sector. Efficiency. Although the power of Teide HPC will greatly benefit from these new resources, advances in photolithography will mean that the new supercomputer will occupy only a quarter of the previous physical space. Its environmental impact will also be zero: the infrastructure will be located in ITER’s own facilities, and will be powered entirely with clean energy from its wind farms and photovoltaic plants.

some experts fear consequences that are difficult to measure

by

There is an initiative to build a gigantic data center in Utah (USA). The so-called Stratos Project plans to occupy an area equivalent to the city of Washington DC and is estimated to consume 9 GW of power. Some experts warn that the thermal impact will be devastatingand they claim that “it is the equivalent of releasing the energy of 23 atomic bombs a day in the form of heat.” A Dantesque project. The approval of Project Stratos occurred at the beginning of May by the Box Elder County Commissionersthe community in northwest Utah on whose land it will be located. The megacomplex plans to occupy 16,100 hectares of surface, and if completed it will become the largest data center on the planet. That record is disturbing and alarming. 9 GW of computing capacity. This data center will consume 9 gigawatts of power, a figure that doubles the current electricity consumption of the entire state of Utah. The figure, like all those surrounding the project, is absolutely exaggerated, and there are many those who have criticized the project. But also GW of heat. The biggest concern for experts It’s not just energy consumptionbut how this will affect the temperatures of the region in which this data center is intended to be built. Robert Davies, a physics professor at Arizona State University, has made the first calculations on this impact and his conclusions are worrying. Because the natural gas plants that will generate electricity for the center are 57% efficient, the complex will produce about 7 or 8 GW of waste heat. Once that electricity reaches the servers, it will be converted into heat, and it is estimated that Project Stratos will emit about 16 GW of thermal energy daily in the Hansel Valley where it will theoretically be located. 23 atomic bombs. Davies points out that this release of heat in a closed basin like the one in this valley is equivalent to “depositing the energy of 23 atomic bombs every day in the local environment.” It is obvious that the project does not generate nuclear explosions or radiation, but it will cause notable climate change. The models estimate that daytime temperatures will increase by 2.7 ºC on average, but the nighttime ones will suffer peaks of up to additional 15.5ºC. The semi-arid climate of the region, one of the driest in the US, will transform into an area with thermal dynamics similar to those of the Sahara Desert. Threat to Great Salt Lake. The location chosen to locate this AI data center is not coincidental: the Hansel Valley is the area through which the so-called Ruby Pipeline passes, a gas pipeline that transports natural gas from Wyoming to the west coast of the United States. The problem is that it is also very close to the northern end of the Great Salt Lake, a body of water that has already been in danger for some time. In fact, its water levels are near historic lows after an unusually dry winter. we were few. The supply contracts indicate an even greater risk to that body of water. The developers plan to acquire local water rights equivalent to about 16 million cubic meters. It is a volume sufficient to cover the basic needs of more than 20,000 homes in Utah. Data center hate is real. This is the latest and most notable case of mega data center construction projects that trigger frontal rejection from local communities in the US. While AI companies and hyperscalers continue to announce new data center construction projects, residents of these areas organize local resistance.

How many Hz will the monitors go up to? LG has a wild new answer: 1000 Hz

by

Carefully choose the monitor The one we accompany our gaming team with is more important than it seems. And be careful, because there are so many specifications to look at when choosing one or the other that finding the right one can be quite an odyssey. Although if we are players of competitive titles, there is one detail to take into account above the others: the refresh rate. Here the choice is clear: the more hertz, the better. AND LG breaks the mold with its new 1,000 Hz monitor. With a 24.5-inch 1080p panel perfect for competitive gaming The UltraGear family of LG monitors will soon grow with a new member who stands out for its monstrous amount of hertz. He UltraGear 25G590Bwhich comes with a 24.5-inch panel with Full HD resolution and 1,000 Hz. It should be noted that it is a native Full HD, compared to other monitors that drop from that resolution to, for example, 720p, to achieve higher refresh rates. This translates into a safe bet for enthusiastic players of PvP titles (player vs player) who want to take the gaming experience to a new level and, in addition, achieve a real competitive advantage: the more hertz, the more FPS they can take advantage of and less latency (or input lag) experience. In other words: faster frame rates, faster actions and an advantage over players with “slower” monitors. Of course, we must bear in mind that to fully squeeze those 1,000 Hz we need a high-end team that offers the highest possible number of frames per second. Desktop (or laptop) configurations with high-end graphics and processors up to the task that, by adjusting the graphic options in video games, comfortably exceed 240, 360 FPS and even more. Keep an eye on the price, yes. For now, We do not know the official arrival date to Spain or how long it will take. (although, according to LG, during the second half of 2026 it will land in several markets to later reach the rest of the world). But we imagine that it won’t be cheap, precisely. if we take into account what other models with high hertz rates cost. Like this AOC 1080p 610 Hz that around 800 euros on Amazon. Or this other MSI, which ups the ante to Quad HD (but drops to 500 Hz), in the same price range. Other gaming monitors with very high refresh rates The price could vary.

sanctioning file and blocked website

by

The Ministry of Consumer Affairs has ordered the blocking of the Polymarket and Kalshi websitesthe two main prediction platforms, and has opened a disciplinary file for operating without the necessary administrative license. The sophistication of the gambling carried out by these platformswho dress the game with an aura of finance or tradinghas not convinced the authorities. The disguise, revealed The Ministry of Social Rights, Consumption and Agenda 2030, directed by Pablo Bustinduy, has responded the question that many have been asking for a long time: They equate Kalshi and Polymarket with a betting house and therefore need the corresponding gaming license, a license which of course they do not have. The General Directorate of Gambling Regulation points out that in Spain, as in other European countries, prediction markets are classified as games of chance since they bet on uncertain future events. The license. In Spain, all gambling operators must be subject to a license that offers a series of guarantees, such as identity verification systems and controlling access to the best of age. In addition, they must control and prohibit access to people who are prohibited from playing. Polymarket and Kalshi do not have this license, which is why Consumo initiated the sanctioning file and has ordered the blocking of their web pages. And now what. At the time of writing these lines, the two websites are still operational, but since The Country They say that the ministry has already notified the telecommunications operators, who have between seven and ten days to execute the blockade. When this occurs, a warning message will appear saying that this is an unlicensed gambling operator. The sanctioning process will last between three and four months until its final resolution. Regulatory clash in Europe. Although with different regulations, the case of Spain adds to a list of European countries that have blocked access to Polymarket, such as France, Germany, Belgium, Poland, the Netherlands or Switzerland. Although there are still countries that allow them to operate, Kalshi and Polymarket face increasingly strong opposition in Europe, with many countries not buying the narrative that they are actually an investment marketplace. Meanwhile in the US. In the United States, however, the platforms are increasingly integrated into public conversation. At the regulatory level, since 2020 CFTC considers Kalshi a licensed prediction market. In the case of Polymarket, the platform It was sanctioned in 2022 for offering contracts without the appropriate regulatory structure, but continues to operate. On the other hand, this same month the congress opened a investigation into possible insider trading (let’s remember the case of the capture of Nicolás Maduro). The debate there is not so much whether they are considered gambling or investment, but rather the origin of the information that is handled. Young men. In a Morning Consult report They say that the usual users of this type of apps are under 45 years old and more than 70% are men. In the United States, 25% of men between 18 and 24 years old admit to having gambled at least once in the last six months. Why young men? According to BBCthese types of platforms are at the intersection of several very masculine cultures, such as sports betting and profit speculation. cryptobros either financebros. It is also successful among this audience thanks to the support of public figures such as Logan Paul, who was sponsored by Polymarket. Where almost everyone loses. We recently talked about a massive analysis that confirmed our suspicions: in Polymarket almost everyone loses while 0.1% of users take almost all the benefits. Those who take the lion’s share of the pie are professional traders who have access to very expensive data sets. In addition, many times the betting conditions have a lot of fine print, even the easiest ones to get right are not that simple. In it Wall Street Journal They tell the story of a man who bet Kalshi that rapper A$AP Rocky would say the word “rapper” on Jimmy Fallon’s Tonight Show. If he was right he would win $168,000. Although he said the word, in the televised version that part was deleted and according to the rules, which were quite hidden, only what was broadcast on television counted. He lost everything.

No drones, no snipers. Wild boar hunters in Barcelona have a simpler natural remedy: a homemade recipe

by

In 2022, a wild boar broke in on a terrace in Cadaqués and took several bags of food in front of dozens of tourists who recorded it with their cell phones while the animal walked between tables as if it had been living there for years. For many residents it was the definitive confirmation that wild boars were no longer occasionally entering the cities: they were beginning to behave like any other inhabitant. Barcelona and the impossible war. It we count a few days ago. Barcelona has been trying for years to contain the expansion of wild boars with health campaigns, population controls, forest surveillance and increasingly sophisticated protocols. However, the animals they keep moving forward street by street from Collserola to the urban heart of the city. The last episode has been especially symbolic: a specimen appeared calmly rummaging through garbage containers on Casanova Street, crossing the street for the first time. psychological frontier of the Gran Via and approaching the Raval. The image perfectly summarizes the underlying problem. While administrations and technicians deploy complex devices to control African swine fever and empty entire forest areas, wild boars continue to enter Barcelona attracted by something much more basic: easy food, accumulated garbage and urban waste converted into a permanent night buffet. The city as a new wild ecosystem. He Eixample case It reflects the extent to which the wild boar has stopped behaving like a strictly forest animal. Neighbors in the area had been reporting saturated containers for weeks, leftover food scattered on the street and a constant accumulation of dirt that attracted rats and other pests. The wild boar simply ended up occupying the last step of that urban food chain. The paradox is that, despite the thousands of copies captured and slaughtered around Collserola to contain swine feverthe city continues to offer exactly what these animals need to lose their fear of the human environment: easy access to food and the absence of predators. The result is a species increasingly accustomed to traffic, lights and densely populated neighborhoods, capable of crossing half of Barcelona during the early hours of the morning with absolute normality. The real secret remains the smell. The most striking thing is that, while Barcelona deploys health protocols, forest controls and institutional campaigns, many hunters have been using methods for years. much more rudimentary to attract wild boars. He viral success of homemade recipes based on anise, fermented corn, sugary soft drinks or sweet mixtures demonstrates the extent to which the animal’s behavior continues to be guided by extremely simple impulses. The strong smell of anise sprayed on cereal or the acidic aroma of fermentation act like a magnet for wild boars, which quickly locate any easy caloric source. This logic also explains what is happening in Barcelona: in the end, technology matters less than the ability to control access to organic waste. the city can deploy surveillance, sanitary sacrifices and mobility restrictions, but as long as there are points where garbage overflows and waste accumulates, it will continue to offer exactly the same stimulus as those improvised feedlots used in the mountains. Fauna altering a big city. I counted the weekend The World that the expansion of the problem is already beginning to have consequences that go far beyond neighborhood coexistence. The outbreak of African swine fever detected in Catalan wild boars has forced sanitary restrictions to be activated that have even ended up affecting the filming of large international productions. the movie The Last Druidstarring Russell Crowe, had to paralyze part of its production in Sant Cugat due to the limitations imposed in forest areas near the health outbreak. The episode illustrates the extent to which wild boar overpopulation has ceased to be a strictly environmental or agricultural problem and has become in a phenomenon with economic, urban and logistical impact. What began as the occasional presence of animals in the limits of Collserola is even beginning to interfere with industrial and cultural activities linked to the territory. Increasingly difficult coexistence. The big problem for Barcelona is that everything indicates that this situation It’s not temporary. Wild boars adapt extremely quickly to urban environments because they find constant food, less hunting pressure and relatively safe refuges in parks, open fields and peripheral green areas. At the same time, cities generate enormous amounts of accessible waste every night. The combination is explosive: animals increasingly trusting entering neighborhoods densely populated while administrations try to balance health control, animal welfare and citizen security. And there appears the great irony of the entire story. After massive campaigns, forestry devices and complex protocols, the battle against wild boars continues to revolve around something very ancient and elemental: the smell of food.

China is about to launch the most powerful cargo drone in the world. And it will move it with hydrogen

by

The aeronautical industry has been researching and experimenting for quite some time. with hydrogen turboprop engines on airplanes. A Chinese company is about to break that barrier, as it has taken off an airplane with one of these megawatt-scale engines. Aero Engine Corporation of China (AECC) has completed the first test flight of the AEP100, installed on a 7.5-ton cargo drone, in an operation that took off from Zhuzhou airport, in Hunan province. what has happened. The device flew for 16 minutes, reached an altitude of 300 meters and traveled 36 kilometers at a speed of 220 km/h before landing without incident. According to AECC, the engine operated stably throughout the flight profile and responded as expected. Chinese state media present it as the world’s first flight with a hydrogen turboprop of this power. Why is it relevant?. Yes, it is a short, unmanned, low-altitude test. But this means that hydrogen aeronautical propulsion leaves the laboratory and test benches to face real flight conditions. AECC maintains that the country already has a complete technological chain for hydrogen aeronautical engines, from essential components to system integration. direct combustion. The AEP100 does not use fuel cells to power an electric motor. It burns liquid hydrogen directly in a turbine cycle, just as a conventional turboprop would burn kerosene. This is the main difference with other bets. Airbus, for example, has prioritized fuel cells on its roadmap to a hydrogen commercial aircraft in 2035, while China has opted for direct combustion. Combustion is more complicated to tame in engineering, but offers much higher power density, something key to scaling up to larger aircraft. What aircraft is it intended for?. The AEP100 is custom designed for the W5000, a twin-engine cargo drone developed by Chinese startup Air White Whale. According to the manufacturer’s data, we are talking about a device with a maximum takeoff weight of 10.8 tons, 5 tons of payload, more than 65 cubic meters of hold and a range of 2,600 kilometers. Just like share from China Daily, when it completes its first flight, it will become the most powerful transport drone in the world, surpassing the Norinco Luca. Deadlines. Yuan An, general manager of subsidiary AE General Aviation Power Tech, has explained The engine is in the final phase of the type certification process and they hope to obtain approval from the Civil Aviation Administration of China in 2027. The process is progressing faster than usual because the AEP100 shares a core with the AES100 turboshaft, which shortens procedures. Yuan has also assured that the AEP100 and its variants will “end the heavy dependence on foreign engines” in Chinese general aviation. Where will it be used first?. For now, we have to forget about getting on a hydrogen-powered passenger plane. The bet goes through what they call the “low altitude economy”that is, situations in which unmanned cargo drones, inter-island logistics or controlled transport routes to remote areas are used, being scenarios where hydrogen refueling infrastructure, certification and operational economics are more manageable than in passenger aviation. Yuan remember also that the United States has more than 275,000 general aviation aircraft, while in China there are only a few thousand. The problems that remain unresolved. Burning hydrogen in a turbine is no small feat, as you can imagine. It burns at higher temperatures than kerosene and with a much higher flame speed, which requires the design of systems that avoid autoignition, flame flashbacks and combustion oscillations. Added to this is storage, since liquid hydrogen requires cryogenic temperatures close to -253 ° C, heavily insulated tanks and, most likely, redesigning the geometry of the fuselage itself to accommodate it. Sustainability. aviation Today it is around 2% of global CO₂ emissions, a figure that could skyrocket in the coming decades if the sector maintains its dependence on fossil fuels. China aims to reduce its exposure to imported oil in an increasingly complicated geopolitical scenario, so hydrogen can fit into both narratives. And now what. China’s road map mark 2028 as horizon to validate similar technologies in small unmanned aircraft, helicopters and urban air mobility, 2035 for applications in broader regions and 2050 for large commercial turbofan aircraft. The first flight of the W5000 with the AEP100 installed is expected in the coming months and will be the next litmus test.

If you are very good at your job and your boss sends you more tasks than the rest, share this article

by

Being the most committed employee in the office has a serious health risk: the more someone enjoys their job, the more trouble they end up making. things that don’t belongwhich are not going to add to your career and which, over time, can end up burning him. At least that’s what he claims an investigation from Cornell University and Northeastern University in which 4,300 employees from different sectors have participated. As and as he declared Sangah Bae, one of its main researchers, Northeastern Global News, This study was born from his own experience as a junior analyst in Chicago: the more involved he became, the more extra work fell on him. Years later, data confirm that this pattern was no coincidence. It’s not a coincidence: it’s a pattern. The researchers found that managers tend to assign additional tasks to employees who perceive as more motivated. In a field survey with 834 middle managers, 55% chose the employee they considered most motivated to assign extra tasks, even when the managers had data on variables such as age, experience or work performance, the perception of the employee’s motivation prevailed in their choice. The laboratory experiment was even more revealing since the researchers designed groups of three people in which one played the role of manager and the other two as employees, competing for a financial bonus linked to their performance. In this scenario, 74% of those acting as managers assigned the extra task to the most motivated employee, even though they knew that this hurt their chances of collecting that bonus. As a result, only about 31.37% of the most motivated employees ended up receiving an extra bonus for their performance improvement. Motivational oversimplification. According to the study According to Bae and Woolley, behind this tendency is a specific psychological mechanism that researchers have called “motivational oversimplification.” The manager’s reasoning is based on the fact that, if this employee enjoys his main job, he will probably also enjoy any extra task equally, even if it has nothing to do with what he usually does and is monotonous and routine tasks that they do not contribute anything. The researchers say that managers “can assume that employees who enjoy their main job will also enjoy additional tasks and that this enjoyment will protect them from burnout.” That is, if it is assumed that the employee will enjoy the task, it is assumed that it will not cost him that much to do it. The study data quantifies this perception gap: managers estimated a drop of just 0.2 points in the motivated employee’s job satisfaction when assigned extra work, while affected employees reported a drop of a full point on that same scale. When motivation turns against you. In one of the study tests carried out over a period of six days, managers chose the most motivated employee 69% of the time, which is equivalent to an average of 4.2 out of every 6 extra tasks assigned. This assignment pattern was repeated every day, which suggests that managers generate systematic inequality in the workload within their teams without being aware of it. “When managers have to assign extra work to their employees, they opt for the easiest option: a person they can trust. That employee who is your shortcut, that person you turn to regularly, who seems to be engaged and enjoy their work, could actually be silently suffering burnout,” Bae said. …and the motivation runs out. As revealed the study OSH Pulse 2025 of the European Agency for Safety and Health at Work (EU-OSHA), 44% of EU workers are regularly exposed to task overload. In Spain, this percentage reaches 49%, and one in three European workers (29%) acknowledges having suffered stress, depression or anxiety caused or aggravated directly by their work in the last twelve months. In Spain, the number of employees affected by task overload rises to 40%. As and how they stand out in Harvard Business Reviewthe study by Cornell and Northeastern Universities adds a new variable that these occupational health data do not include: this burden is not distributed randomly among all employees of a company, but rather tends to concentrate precisely on the employees who are most involved.

“Going to the gym for an hour” is not worth spending eight hours sitting. And there is a deep evolutionary reason for that.

by

They have slipped it on us and it is time to recognize it. For years, the gym boom has been received with enthusiasm: having ubiquitous and accessible sports facilities to get us out of our sedentary routine can only be understood as something positive. And yet, the way sport has entered our lives is deeply problematic: we have managed to create a “compartmentalized model” of physical activity that is leaking everywhere. So “going to the gym” doesn’t work? No, it’s not that. It’s not what the evidence says. Intense exercise is helpful. Very useful. And it is always better than doing nothing: but the idea of ​​going to the gym for an hour and that’s it forgets that the relevant unit is not the hour at the gym, but the energy pattern of the 24 hours a day. Let’s put it another way: Why do the Hadza They do not burn more calories than office workers despite walking 12 km a daywhy weight loss gym programs consistently disappoint or why the WHO has begun to separate “exercise” from “sit less”? The answer to these three questions is the same: the evolutionary biology of the human being. Two lines of research that converge at the same point. Between 2012 and 2018, a team from Duke University coordinated by Pontzer discovered that the body It is not dedicated to linearly adding exercise expenditure to basal expenditure. What it does is compensate for it (reducing expenditure on other vital functions such as inflammatory, reproductive processes or metabolic control). That is, doing an hour (or more) of intense exercise does not have to increase total energy expenditure. The second line of research arises from comparing people with the same weight and height. In ’99, the Mayo Clinic discovered that the daily difference in energy expenditure can be attributed to things like walking, standing, housework, and other types of small unconscious movements. To this we must add that a sedentary lifestyle is, in itself, a risk factor. In 2016, Ekelund and his team discovered that between 60 and 75 minutes a day of moderate physical activity are needed to eliminate the excess mortality risk associated with sitting for 8 hours or more a day. That is, one hour of exercise does not solve the problem. And the problem is that the public conversation doesn’t realize it. It is unbalanced: the dominant imagination since the 80s sees doing “a handful of hours of exercise” as a way to “buy” health. The very long debate about how many steps to take each day is exactly the same. The issue, as I say, is that the evidence is clear that we are not buying anything. And then? Should we close the gyms? Nothing of the sort. The important thing at this point in 2026 is to begin to understand that the correct unit to think about our physical activity is the full day. As the WHO says“more activity is better than little; any activity is better than none; (however) reducing a sedentary lifestyle provides independent benefits” and is worth addressing regardless of the exercise we do. The idea of ​​”training for an hour and then spending the rest of the day calmly” does not hold water. Going to the gym is positive, but it is not a papal bull: intense exercise works as something that adds to leaving a sedentary lifestyle. It does not replace it.

We Spaniards are changing fishmongers for fish on a platter. And it is costing us very expensive

by

When your grandparents wanted to buy fish, they might have found more or less variety, but they had it easy: they went to the market or the fishmonger, asked questions, chose, paid and returned home with the purchase. Today things are somewhat more complicated. Or not. with consumption in low hours and food spending increasingly concentrated In supermarkets (to the detriment of neighborhood stores), it is increasingly common that instead of buying salmon, sea bream or any other fish on a counter, we take it from a refrigerator, already scaled, filleted and served on trays. The question is… Does that make it more expensive for us? What has happened? that the OCU just responded to a question that you may have asked yourself more than once if you usually consume packaged fish from the supermarket: Are you paying a premium? Would that filleted fish be cheaper if you bought it in the fishmonger’s section instead of on a tray? It is an interesting question if we take into account that Mercadona, the chain with higher market share of the country and agglutinator of more than 30% of the food distribution business in some parts of Spain, has decided retire their fish counters and bet on the sale of this product already prepared, packaged and arranged on trays. What has the OCU found out? In general terms, it is (indeed) likely that you are spending more money by taking home already packaged merchandise instead of buying it at the supermarket fishmonger. After carrying out a study in a dozen chains throughout April, the OCU concluded that “fresh fish sold packaged is up to 30% more expensive than that purchased at the fishmonger if they are small varieties, already cleaned and filleted.” That last nuance is important because the organization’s technicians verified that the percentage goes up or down depending on the type of product we are talking about. In some cases the extra cost of packaged fish compared to that sold over the counter shoots up to 45%. In others it narrows so much that it is almost imperceptible. “The answer is not as simple as it seems: in some cases, especially for smaller or portioned fish, we do pay a lot more to buy clean fish on a tray, but in others, for larger ones, there is almost no difference,” details the OCU. Can it go further? Yes. To begin, it is useful to know how your study was carried out. As recognizes the OCU itselfthe analysis is not as simple as writing down the cost (euros per kilo) of each product and then comparing. There are chains that only sell certain varieties of fish through a single channel (counter or trays). As if that didn’t complicate things enough, there is another key handicap: trays of filleted and packaged fish usually offer 100% edible product; That is, without bones, heads or any other disposable part, something that can happen with whole pieces from the fish market. And how did they calculate it? How can we compare the prices of trays of already cleaned fish with those we see in fishmongers, which usually show the cost €/kg of whole pieces? To solve it, the OCU was based on estimates from the Spanish Nutrition Foundation that they conclude that the edible part of the fish usually represents more or less between 55 and 67%, depending on whether we are talking, for example, about sea bream or sea bass. As for the chains, the OCU set in Ahorramás, Alcampo, Aldi, BM, Carrefour, Dia, Hipercor, La Despensa, Lidl and Mercadona. If we talk about gender, the analysis focused on four species frequently consumed in homes: sea bream, sea bass, hake and salmon. For referencethroughout the year between October 2024 and November 2025, we Spaniards consume 0.56 kg of sea bream, 0.55 of sea bass, 1.44 of salmon and 1.54 of hake. Do those details matter? Yes. Because thanks to them we can better understand how the gap between the price of fish on the counter and on a tray widens or narrows depending on the product we are talking about. The clearest cases are represented sea ​​bream and sea bass. In the first case (gilthead) the OCU calculates that merchandise sold packaged is on average 27% more expensive. And at the counter we also pay for the amount of merchandise that is wasted after weighing the complete piece. In some supermarkets that percentage even shot up to 47%. The case of the sea bass is even more egregious. The surcharge detected in filleted products served on trays is 45%. Is it always like this? Things change considerably when we talk about hake and salome. If we want some slices or loins, there are no big differences depending on whether we ask the fishmonger at the counter or go to the supermarket refrigerator to buy them in trays. A hake cut and prepared on the counter came out in April for €17-25/kgwhile on a tray it was charged at €18-25/kg. The salmon slices or loins also cost practically the same (€20-23/kg) both in the fishmonger and in boats. What is the conclusion? “The conclusion is clear: in small fish, the greater the handling, the more expensive the fish on a tray becomes compared to selling on the counter. In preparations with less handling, the premium is much lower, if not residual,” ditch the organization. In short: there is a premium, although it is not always nor is it equally forceful in all cases. It depends on the type of fish and also the level of preparation we want. “In small and filleted fish, convenience does pay.” Better one or the other? The OCU admits that the trays have “pros and cons” for both consumers and supermarkets. Among the first, the most obvious is speed and comfort. One of its biggest drawbacks is the loss of the figure of the fishmonger, crucial for advising the client, and the generation of waste. The organization also warns … Read more
