Wild capture criterion scoring overview
This system has been developed by the Marine Conservation Society to help consumers choose the most environmentally sustainable fish. For full details, please see the full wild-capture methodology available here.
Stock or species status
| Score | Descriptor |
|---|---|
| 0 | Stock under fished and harvested within sustainable limits |
| 0.25 | Stock fully fished and harvested within sustainable limits |
| 0.5 | Stock level below sustainable level (BMSY) but harvested within sustainable limits |
| 0.75 | Stock and fishing level or stock at increased risk |
| 1 | Stock outside biological and/or safe fishing limits |
Management
| Score | Descriptor |
|---|---|
| 0 | Well-managed |
| 0.25 | Management requires some improvement |
| 0.5 | Partly effective management |
| 0.75 | Poorly managed and requires considerable improvement |
| 1 | No relevant or effective management measures in place |
Capture method and ecological effects
| Score | Impact |
|---|---|
| 0 | Very low impact |
| 0.25 | Low impact |
| 0.5 | Some or moderate impact |
| 0.75 | High impact |
| 1 | Very high impact or illegal |
Where environmental concerns from any one criteria are so great, a ‘critical fail’ may be triggered and the fishery awarded a default red rating. For full details, please see the full wild-capture methodology available here.
What’s a sustainability range?
Many of the fish listed are caught in different ways and from different areas of the sea. Some species are caught in a variety of ways and this range shows that, within a species, some may be fished sustainably whilst others unsustainably.
To find out the individual ratings for each fish click on the ratings button next to the image.
'Best choices' are rated 1 and 2, Fish to Avoid are rated 5. Ratings 3 and 4 mean don’t eat too often.
Fish that are being assessed are shown with a question mark icon and "No Rating".
This system has been developed by the Marine Conservation Society to help consumers choose the most environmentally sustainable fish.
To be assessed
Seafood sources indicated as, 'To be assessed', are those that have not yet been assessed and assigned a rating or are undergoing a period of review. These include sources previously rated by MCS for which the rating has lapsed, due to changes in the market or MCS priorities and resources. Given that these sources are not fully assessed, the profile should not be used to infer the current sustainability of the fishery or farmed species.
If you are interested in the sustainability of this seafood source, please let us know by emailing ratings@mcsuk.org
Rating 1
Rating 1 (light green) is associated with the most sustainably produced seafood.
Fish to Eat are rated 1 and 2, Fish to Avoid are rated 5. Ratings 3 and 4 mean don’t eat too often.
This system has been developed by the Marine Conservation Society to help consumers choose the most environmentally sustainable fish.
Rating 2
Rating 2 (pale green) is still a good choice, although some aspects of its production or management could be improved
Fish to Eat are rated 1 and 2, Fish to Avoid are rated 5. Ratings 3 and 4 mean don’t eat too often.
This system has been developed by the Marine Conservation Society to help consumers choose the most environmentally sustainable fish.
Rating 3
Rating 3 (yellow) based on available information; these species should probably not be considered sustainable at this time. Areas requiring improvement in the current production may be significant. Eat only occasionally and check www.goodfishguide.org for specific details.
Fish to Eat are rated 1 and 2, Fish to Avoid are rated 5. Ratings 3 and 4 mean don’t eat too often.
This system has been developed by the Marine Conservation Society to help consumers choose the most environmentally sustainable fish.
Rating 4
Rating 4 (orange) should not be considered sustainable, and the fish is likely to have significant environmental issues associated with its production. While it may be from a deteriorating fishery, it may be one which has improved from a 5 rating, and positive steps are being taken. However, MCS would not usually recommend choosing this fish.
Fish to Eat are rated 1 and 2, Fish to Avoid are rated 5. Ratings 3 and 4 mean don’t eat too often.
This system has been developed by the Marine Conservation Society to help consumers choose the most environmentally sustainable fish.
Red Improver
'Red improver' ratings are assigned to seafood sources which have been assessed and rated 5 (red) due to significant environmental concerns with one or more aspects of their management, capture or production, yet credible efforts to improve these issues have been agreed through a Fisheries or Aquaculture Improvement Project – a FIP or an AIP - and work is underway. Such projects are normally publicly listed at www.fisheryprogress.org. MCS wants to encourage environmental improvements in fisheries and fish farms, and so does not recommend avoiding these sources, as we normally do for seafood rated 5 (red rated).
'Best choice' fish are rated 1 and 2, Fish to Avoid are rated 5.
This system has been developed by the Marine Conservation Society to help businesses and consumers choose the most environmentally sustainable fish.
Rating 5
Rating 5 (red) is associated with fish to be avoided on the basis that all or most of the criteria for sustainablilty have not been met.
Fish to Eat are rated 1 and 2, Fish to Avoid are rated 5. Ratings 3 and 4 mean don’t eat too often.
