The environmental impact of fishing is well documented, but sometimes shopping for sustainable seafood alternatives can feel like an expense too far.
The Marine Conservation Society has updated its Good Fish Guide to help seafood lovers make more informed and sustainable choices – without it costing an arm and a leg.
By opting for fish species that are abundant and responsibly caught (and perhaps ones you might not think of!), you can enjoy nutritious meals while supporting the health of our oceans.
Here are some top tips for making sustainable, affordable choices at the fishmonger.
How to buy for sustainable seafood on a budget
Diversify your fish choices
In the UK, many of us tend to rely on a handful of familiar species: cod, haddock, salmon, tuna and prawns. However, there are plenty of other sustainable and affordable alternatives out there.
Species like coley, hake and pollock are abundant and come from more plentiful stocks, making them better choices for the environment. By diversifying your seafood, you can help reduce pressure on overfished species. Embrace the unknown!
If in doubt, ask a fishmonger
Your local fishmonger can be an encyclopedia of knowledge when it comes to sourcing sustainable seafood. Don’t hesitate to ask for their advice on what’s fresh, local and in season.
They can also recommend sustainable options such as farmed rainbow trout or Arctic char, which are great local choices for those looking to reduce their environmental impact.
Try tinned
Canned fish like anchovies and sardines are not only rich in healthy omega-3 fats but also often come from more sustainable fisheries.
Look for tins marked with certifications or check the Good Fish Guide to ensure the fish supports ocean-friendly practices. Sardines from Cornwall and anchovies from the Bay of Biscay are both sustainable and delicious options to try.
Give mussels a go
Mussels are a great eco-friendly seafood choices. They’re grown using methods that have minimal impact on the marine environment and are often harvested by hand. Try cooking them with white wine and garlic for a simple, sustainable dish that won't break the bank.
Out with fillets, in with fish
Instead of buying pre-cut fillets from the supermarket aisles, try buying the whole fish from the fish counter. Not only does this approach reduce waste, but it also offers better value for money.
By using every part of the fish, including bones and skin, you can make homemade stocks and reduce waste. Hake or lemon sole from the North Sea are excellent options to consider.
Don't dismiss frozen options
Buying frozen fish in bulk can help cut down on food waste while often providing better value for money. North Sea haddock, for example, is a sustainable frozen fish option that is widely available.
Freezing fish extends its shelf life, making it easier to keep your seafood supply stocked without contributing to unnecessary waste.
Look for alternatives to mackerel
Once considered a sustainable choice, North East Atlantic mackerel has unfortunately been overfished by as much as 23 per cent in recent years. The Marine Conservation Society recommends alternatives such as herring from the North Sea and eastern English Channel or sardines from Cornwall, which are both more sustainable options for supporting ocean health.
