Good Fish Guide
Your guide to sustainable seafood
You can play a key role in securing the future of our seas and marine wildlife by making more environmentally responsible choices when buying seafood.
Our seas face a wide range of threats. Climate change, pollution, habitat and biodiversity loss are all impacting our seas; plus 90% of global fish stocks are either fully or over-exploited. All these factors combined mean that urgent action is needed to restore the health of our seas. Fish farming (aquaculture) is rapidly expanding to meet increasing demand for seafood, but if this is done badly it can also damage the environment and exacerbate these other problems.
Use the Good Fish Guide to find out which fish are the most sustainable (Green rated), and which are the least sustainable (Red rated). Make the right choice and reduce your impact – every purchase matters! Find out more about our seafood work, including how we develop our seafood ratings, plus sustainable seafood recipes and more.

Tuna, Atlantic bluefin (Caught at sea)
Bluefin tunas are vulnerable, slow growing and long lived species that are heavily exploited across their range. The market value of individual fish regularly reaches tens of thousands of pounds with the record being over a million pounds … Read more for just one fish! This is a strong incentive for illegal fishing which has been extensive in the past. Management has improved, particularly for Atlantic and southern bluefin, but Pacific bluefin continues to be subject to heavy overfishing. Pacific bluefin remains at or near historical lowest levels; southern bluefin remains listed as Critically Endangered by the IUCN. Atlantic bluefin is listed by the IUCN as Threatened in Europe and Endangered in the Mediterranean. As it is recovering quickly though, MCS is reviewing its rating for the Atlantic bluefin species.
