How can I buy fish sustainably?

1. Mix up the fish you choose

• Buy in-season and locally sourced if possible.
• Choose different fish, not just your usual favourites – 80 per cent of the seafood we eat in the UK is made up of just five species: cod, haddock, salmon, tuna and prawns. This puts a lot of pressure on the sustainability of these species – so mix it up and try something new – why not swap prawns for mussels or clams?
• Trust your fishmonger – they should have all the knowledge about their product and be able to inspire you with some tasty alternatives.

2. Stay informed

The Marine Conservation Society uses scientific research to gather information. Their yearly Good Fish Guide traffic light system helps the consumer make sustainable seasonal choices. The website is full of information and definitely one to keep an eye on each time you shop.

3. Look for the Marine Stewardship Council certification

The Marine Stewardship Council (MSC) certify seafood stocks considered to be fished at sustainable levels. This information is updated regularly. Many species carry the familiar blue tick logo on the label.

If you can’t see this, ask the fishmonger – sometimes small fisheries can’t afford the certification but do fish in a responsible way.

4. Read up on farmed fish

Currently more than 50 per cent of the seafood we consume is farmed. To enjoy seafood into the future, aquaculture has an important role to play. Many concerns about farmed practices have been addressed in some areas including the use of antibiotics, feeds and stocking density.

There are four global schemes responsible for the majority of certified aquaculture production – Aquaculture Stewardship Council, the Global Aquaculture Alliance Best Aquaculture Practice, GlobalG.A.P and Friend of the Sea.

5. Fishing for Litter

Many fishermen are concerned about waste litter, improving their fishing gear and other important environmental issues. New initiatives include recycling fishing equipment and sending it to third world countries for re-use.

Fishing for Litter is a scheme where fishermen are given large bags to gather debris collected in nets during fishing. They are also improving gear efficiency to lessen by-catch (unwanted species) and minimise damage to the seabed.

6. Sea Fish UK

Sea Fish UK are the authority that advise across the industry – from sea to plate. They cover everything from promoting the consumption of seafood, to improving the health of the consumer and ensuring fishermen are safe at sea.
