Seafood ratings

Fish Ratings

Each of the fish have been given a rating to enable you to quickly identify species that are considered to be sustainably and sensitively harvested, and those species which are not:

• vulnerable to exploitation and/or assessed by the World Conservation Union (IUCN) as threatened and/or;
• from overfished stocks and/or stocks where data is deficient and/or;
• from poorly managed or unregulated fisheries and/or;
• caught using methods which are detrimental to other marine species and habitat;

and are:

• from fisheries certified as environmentally responsible.

Rating 1 is awarded to the most sustainably produced seafood including fish from certified fisheries

Rating 5 is awarded to fish to be avoided on the basis that all or most of the above statements apply.

Ratings 2, 3 and 4 indicate that there is an increasing cause for concern, based on the information available at the time of publication.

The rating system has been developed by the Marine Conservation Society as a guideline only, to eating the most environmentally responsible fish.
