1. Cultivated Seafood
Cultivated seafood offers a way to enjoy genuine seafood without relying on traditional fishing or aquaculture. By growing fish cells in controlled lab environments, this technology creates seafood that is biologically identical to what you’d find in the ocean. Let’s dive into how cultivated seafood measures up in terms of taste, nutrition, environmental impact, and safety.
Taste and Texture
Taste and texture are deal-breakers when it comes to seafood, and cultivated options are proving to be strong contenders. Early reviews from chefs and diners highlight that cultivated seafood mirrors the flavour and texture of traditional fish impressively well. For instance, Wild Type’s cultivated salmon has been praised for its authentic taste and mouthfeel, making it nearly indistinguishable from its ocean-caught counterpart.
This attention to detail isn’t limited to salmon. AQUA Cultured Foods has developed cultivated scallops designed to replicate the delicate texture and oceanic flavour of real scallops. They’ve achieved this while using minimal plant-based ingredients to maintain authenticity. That said, cultivated seafood does come with slight differences, such as variations in moisture levels and fat distribution, which might require small tweaks in cooking methods to bring out the best results. While the end product feels familiar, chefs may need to adjust their approach to maximise its potential.
Nutritional Profile
Cultivated seafood doesn’t just aim to taste like the real thing - it’s designed to be nutritionally on par or even better. These products are crafted to deliver the same protein and omega-3 fatty acids that consumers expect from fish. What’s more, the controlled production environment allows for fine-tuning - companies can boost beneficial fats or even reduce allergens compared to traditional seafood.
One of the standout advantages is what cultivated seafood doesn’t contain. Unlike wild-caught or farmed fish, these products are free from common contaminants like mercury, microplastics, and antibiotics. This cleaner profile appeals to consumers who are increasingly concerned about ocean pollution and its impact on seafood safety.
For those with specific dietary needs, cultivated seafood offers further reassurance. The absence of hidden additives makes it a safer option for individuals with coeliac disease or gluten sensitivities, providing peace of mind without compromising on taste or nutrition.
Environmental Impact
The environmental benefits of cultivated seafood are hard to ignore, especially given the challenges our oceans face today. With fish stocks dwindling, this technology provides a sustainable alternative that eases the strain on overfished populations while meeting the growing demand for seafood.
Traditional fishing methods often result in bycatch - the accidental capture of non-target species. Cultivated seafood eliminates this issue entirely. Additionally, it avoids the environmental damage caused by practices like bottom trawling and the pollution risks linked to intensive aquaculture.
From a climate perspective, cultivated seafood has a smaller carbon footprint. It produces fewer greenhouse gas emissions and requires less water and land compared to conventional aquaculture. As climate change continues to disrupt ocean ecosystems, these advantages make cultivated seafood an increasingly appealing option.
Food Safety
Food safety is where cultivated seafood truly shines. Produced in sterile, controlled environments, it minimises the risks associated with traditional seafood, such as bacterial contamination, parasites, and toxins from polluted waters.
The growing support from regulatory bodies is further strengthening consumer trust. In the UK, the government has introduced a regulatory sandbox for cultivated proteins, streamlining the approval process while ensuring strict safety standards. Companies like Umami Bioworks are taking advantage of this framework to prepare for market launches.
For those curious about the future of cultivated seafood in the UK, Cultivated Meat Shop offers educational resources and product previews.

2. Traditional Seafood
Traditional seafood holds a cherished place in British cuisine, reflecting its deep-rooted cultural and culinary significance. This section explores the characteristics that define traditional seafood and why some are turning to cultivated alternatives.
Taste and Texture
The flavours and textures of traditional seafood are as varied as the oceans themselves. White fish like cod and haddock offer mild, delicate flavours and flaky, tender textures, making them staples in classic dishes such as fish and chips. On the other hand, oily fish like salmon and mackerel bring richer, stronger flavours and firmer textures, ideal for grilling or smoking.
Shellfish add their own distinct charm. Prawns and scallops, for instance, are celebrated for their sweet, delicate taste and soft yet slightly chewy texture. These qualities are shaped by natural conditions that have been relied upon for centuries in kitchens across the UK.
Wild-caught fish often stand out for their firmer texture and more intense flavour compared to farmed varieties, a distinction many seafood lovers appreciate.
Nutritional Profile
Traditional seafood is often praised for its nutritional benefits. It’s a rich source of high-quality protein, omega-3 fatty acids, and essential vitamins and minerals like vitamin B12, vitamin D, iodine, selenium, and zinc. These nutrients play a vital role in supporting brain function, heart health, and the immune system.
However, it’s not without its drawbacks. Some species can carry contaminants like mercury, which is why specific consumption guidelines exist for vulnerable groups, including pregnant women and young children. This balance of benefits and risks highlights the complexity of traditional seafood as a dietary choice.
Environmental Impact
Traditional seafood faces serious environmental challenges. Overfishing has depleted nearly 90% of global commercial fish stocks [1], putting immense strain on marine ecosystems. Harmful practices like bottom trawling destroy seafloor habitats, while bycatch - the unintentional capture of non-target species - remains a pressing issue.
Although aquaculture addresses some concerns tied to wild-caught fish, it introduces its own problems. These include pollution from fish waste, the use of wild fish in feed, and the potential spread of diseases to wild populations. In the UK, where over 70% of seafood is imported [5], efforts are underway to promote more sustainable practices. For instance, the Cornish Sardine Company has achieved MSC certification for its eco-friendly fishing methods, and Scottish salmon farms are adopting innovations like closed containment systems to reduce their environmental impact.
Food Safety
Ensuring the safety of traditional seafood requires stringent measures throughout the supply chain. According to the Food Standards Agency, 1 in 10 cases of foodborne illness in the UK can be traced back to seafood [5], often due to improper storage or handling rather than the seafood itself.
Contamination risks are a key concern. Mercury, microplastics, and pathogens like Listeria and Salmonella can pose health risks. Wild-caught fish may be exposed to pollutants in their natural habitats, while farmed fish could carry residues from antibiotics or other treatments. To address these issues, the seafood industry adheres to strict hygiene standards, traceability protocols, and regular testing. In the UK, seafood must meet FSA guidelines, which cover everything from fishing practices to labelling. Proper storage at 0–4°C and following consumption guidelines further reduce risks.
Despite these challenges, traditional seafood remains a favourite among UK consumers, with the average person consuming about 24kg of seafood annually [5]. Popular choices like salmon, cod, and haddock continue to dominate dinner plates, underscoring the enduring appeal of traditional seafood even as the industry grapples with safety and environmental concerns.
Advantages and Disadvantages
Here’s a closer look at how cultivated seafood stacks up against traditional seafood, highlighting their respective strengths and trade-offs:

High production costs remain a major challenge, though industry leaders are optimistic about reaching cost parity with traditional seafood by 2030 as production scales up and technology improves.
Consumer access is another hurdle. At present, cultivated seafood is primarily available in select restaurants and foodservice channels, making it inaccessible for home cooking in the UK. This strategy focuses on controlled, small-scale launches rather than widespread retail distribution.
Environmental benefits are a major draw, particularly as cultivated seafood addresses two of the biggest issues with traditional methods: overfishing and bycatch. By eliminating these problems, cultivated seafood offers a more sustainable alternative to conventional fishing, which has significantly depleted fish stocks [1].
Health-conscious consumers are also drawn to its superior safety profile. Unlike wild-caught or farmed fish, cultivated seafood is free from mercury, microplastics, and antibiotic residues, thanks to its controlled production environment that minimises contamination risks [1].
However, regulatory challenges have slowed its market expansion. While Singapore has approved Halal certification and the FDA has cleared Wildtype's salmon for sale [1], the EU's complex regulatory process - requiring approval from all 27 member states - has led some companies, such as Bluu Seafood, to focus on non-EU markets first [4]. These regulatory delays increase costs and create uncertainty for potential investors.
Consumer interest is growing, with 62% of UK and US consumers open to trying cultivated seafood, largely due to concerns about sustainability and health [1]. Yet, the current high prices and limited availability may deter budget-conscious shoppers during these early stages.
Despite these challenges, scalability is advancing quickly. For instance, fermentation capacity at key facilities is expected to grow significantly by the end of 2025 [4]. This rapid progress contrasts sharply with traditional fishing, which is inherently limited by natural resources.
