What are sardines?
Sardines (also known as pilchards) are a small, oily fish packed with flavour and nutrients, making them a great option for anyone looking to eat more sustainably. They are a type of small schooling fish found in oceans around the world. In the UK, we sometimes use the term pilchards to refer to larger, mature sardines.
Their abundance and fast reproduction rates make them a strong sustainable seafood choice.
Are sardines sustainable?
Sardines are a sustainable form of seafood when sourced from well-managed, certified fisheries. Their relatively short life cycle and healthy population levels contribute to strong sustainability credentials.
Choosing certified sardines helps ensure:
- Fish stocks remain healthy
- Marine ecosystems are protected
- Fisheries are responsibly managed
You can find sustainable sardines in the UK which are caught in well-managed fisheries by looking for the MSC blue ecolabel, to make sure it’s from a trustworthy source.

Historical bite
Sardines have been fished in Cornwall for 500 years. Just over a century ago there were dozens of plants salting pilchards to supply the booming Continental market. But by the 1980s, with more fresh and frozen fish available, pilchard fishing diminished along with the market.
“We want this fishery to be successful. It’s been a huge success and we want to ensure it goes on as much as possible. The stock biomass goes up each year and we are fishing well within the limits of that. We collect scientific data a couple of times a week to support the management of the fishery. We're very proactive so that it remains a success story for future fisherman. Why would you not want fish for the future?”
