The fish2fork.com rating system is designed to inform customers whether a restaurant is doing all it can to serve sustainable seafood and reduce its impact on our oceans at a time when overfishing is perhaps the greatest threat to marine life on 70 per cent of the planet's surface.
It also functions as a regular restaurant review website where diners can share their culinary experiences with others.
Restaurants are scored for the sustainability of the fish on their menu and their sourcing policies by filling in our questionnaire. Restaurants are invited to fill in these questionnaires, as are their customers.
When rating restaurants, we look to see whether any of the seafood they are serving is listed as an endangered species on the IUCN Red List; we also look at whether any of the seafood they serve appears as a "fish to avoid" - because fish stocks are not well managed - on the guides published online by Monterey Bay Aquarium's Seafood Watch in the USA or on the similar Good Fish Guide compiled by the Marine Conservation Society in the UK.
We also score and review restaurants according to whether they provide full information about which species of fish or shellfish they serve on the menu, whether they say if it is farmed, and whether they state how it is caught. If the fish is farmed, we look at whether trouble was taken to avoid depleting overfished fish stocks of small fish used in fish food. We look at whether the restaurant has a policy on sustainable seafood sourcing where fish is caught by the most selective and least damaging methods, such as the Seafood Watch pledge, and whether fish are traceable from "boat to plate".
Where restaurants have declined, or otherwise been unable, to complete a questionnaire, fish2fork.com has awarded ratings on information available on their websites during the initial survey period. We believe it is entirely valid to rate restaurants principally by their online offering as this is often the principal means that concerned customers can decide whether to visit a restaurant in the first place. We believe that it is in a restaurant's interests to provide us with information on its sourcing policies, however, as there is a limit to the information that can be carried on the menu.
We have gone to some trouble to check all the information on this website, but if we have got any entry wrong for any reason, please let us know and we will quickly correct it.
Scores are converted into a rating: the best restaurants for sustainability receiving up to 5 Blue Fish and the worst, up to 5 Red Fish. Our reviews will tell you why we have awarded the ratings we have, but we will always welcome your views and findings.
