When it comes to fish in the UK, the mind often jumps straight to cod and haddock, the reliable duo found in chip shops across the country. While these remain beloved staples for good reason, there’s far more to discover in British waters. From familiar names to underrated gems, our coastal seas offer a diverse selection of fish and shellfish that are not only delicious but also more sustainable. With a little knowledge and curiosity, it’s easy to explore new flavours while making responsible choices.
Beyond the Classics
Cod and haddock are well known for their mild flavour and flaky texture, making them family favourites for generations. Haddock, in particular, is used in traditional dishes like the hot-smoked delicacy from northeast Scotland known as Arbroath Smokies. Cod, meanwhile, remains a go-to choice for fish and chips. However, it’s worth keeping sustainability in mind when shopping. Opting for responsibly sourced fillets, particularly those certified by recognised organisations, is a great way to support healthy fish stocks.
Salmon and mackerel are two more widely consumed species, each with their own benefits. Salmon is a popular mealtime regular, while mackerel offers a rich source of omega-3 and reproduces quickly, making it a sound, sustainable choice. Mackerel is best eaten fresh, so it’s ideal to seek it out from a trusted local source where freshness is guaranteed. For those living near the coast or close to a specialist fish counter, there are excellent options for fresh seafood in Bangor and other parts of the UK.
Sustainable Alternatives Worth Trying
For those looking to branch out, several lesser-known fish offer fantastic flavour and a lighter impact on marine ecosystems.
Coley, for instance, is a close relative of cod but tends to be more affordable and versatile. Its soft texture and mild taste make it perfect for pan-frying or baking, and it works well in traditional recipes.
Hake is another fantastic option. Its firm white flesh makes it a great substitute for cod in fried or grilled dishes and is often highlighted in restaurant menus for its clean flavour.
Gurnard, once undervalued, has found new popularity among chefs. Its firm texture and subtly sweet flavour lend well to roasting, particularly with Mediterranean vegetables.
Off the Cornish coast, sardines (also known as pilchards) are abundant and full of omega-3. Simply grilled with a squeeze of lemon, they’re an easy, healthy addition to any meal.
Shellfish from UK Shores
UK waters also boast a rich array of shellfish. Rope-grown mussels are among the most sustainable seafood choices available and are easy to prepare in a dish like moules marinière, with garlic, white wine and herbs.
Crab, especially from northern waters, provides sweet, delicate meat that can be used in sandwiches, salads, or pasta.
Other favourites include cockles and clams, both of which bring a fresh, briny taste to steamed dishes or seafood linguine.
Coastal Catches in North Wales
In towns along the Welsh coast, particularly in Llandudno, Wales, seafood has long been part of local life. Waters off the North Shore regularly produce species like mackerel during the warmer months, as well as flatfish such as plaice and flounder. Wild sea bass can occasionally be found too, offering a rich, flaky texture. Local shellfish is also common and often featured in restaurants and fish counters throughout the area.
Easy Recipes to Try at Home
Trying something new doesn’t need to be complicated. Here are two straightforward ideas to get you started:
Pan-Fried Coley:
Season coley fillets with salt and pepper, then pan-fry in olive oil for 3–4 minutes on each side. Serve with steamed greens and lemon.
Roasted Gurnard with Peppers:
Place whole, gutted gurnard in a roasting tray with sliced peppers and onions. Add olive oil, a splash of white wine, and a little seasoning, then roast at 180°C for around 20 minutes.
Choosing Seafood Responsibly
Whether you’re cooking at home or eating out, choosing fish with sustainability in mind makes a real difference. Look for the blue ecolabel from reputable certification schemes or consult resources that help guide your seafood choices. By thinking beyond the familiar and embracing the wider selection available, it’s possible to enjoy a more varied and environmentally responsible diet.
Exploring British seafood doesn’t have to be complicated. With a few new ideas and a willingness to try, it can open the door to fresh meals, healthier choices, and support for local fishing communities all in one.
