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 - click to expand
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.

Smoothhound
Mustelus spp.
Smoothhound is one of few shark species whose numbers appear to be stable at present, however there is much uncertainty about its stock status. Unlike many similar elasmobranchs, their relatively high productivity means that there is … Read more potential for this species to be harvested sustainably. However, data are lacking on their biology, and level of fishing on the species which precludes the ability to manage them effectively.

Sole, Lemon
Microstomus kitt

An exception to this is in Cornish waters where a MLS of 25cm is enforced by local byelaw. There is no formal … Read more assessment of the North Sea stock but analysis of survey data suggests that fishing mortality is below and stock size above sustainable reference points. Choose seine caught fish where possible, as this method of capture causes less damage to the seabed and is the best choice for lemon sole from the North Sea. Avoid eating immature fish (below 25cm) and if eating fresh from the sea, avoid its breeding period, April-August.

Squalus acanthias

where it gives birth. Sharks, skates and rays are fish, but they can be distinguished from bony fish (teleosts) by their cartilaginous skeletons. There are four main types of cartilaginous fish; sharks, skates and rays, collectively called elasmobranchs, and the rarely encountered chimaeras, a more distant relative only found in deep water. They are also distinguished from bony fish by the way they breed. Reproduction in sharks and rays is a very slow process as they have a late age of sexual maturity, produce few young and have a long gestation period. No maternal care is provided to shark pups, instead they are well-developed and ready to hunt when born in order to maximise their chance of survival. All shark eggs are fertilised internally but may develop in one of three different ways: Eggs are held within a leathery case (Oviparity), known as a mermaids purse, e.g. catshark; Embryos develop within the mother and are nourished by the egg (Ovoviparity) e.g. basking shark; Embryos develop within the mother and are provided with nutrients from a placenta (Viviparity) e.g. smooth-hound. World-wide sharks are being removed from our seas at an alarming rate. Sharks are slow growing, long-lived with low reproduction. Finning is perhaps the most damaging and distasteful of all shark fisheries. The process is cruel and wasteful, involving the removal and retention of fins, while the rest of the shark, is discarded, often still alive, to drown or be eaten. Finning takes place all over the world (including Europe) to feed the continual and increasing demand for sharkfin soup. Fins are consumed principally in the Far East but Europe and the USA are sizeable markets for shark fin. Blue sharks and other oceanic species are the preferred species taken. British seas are home to over 30 shark species including the fastest shark in the world (the shortfin Mako) and the second largest fish in the world (the Basking shark) and we even get tropical rare visitors such as hammerheads.
Spurdog (spiny dogfish, rock salmon or flake) are long-lived, slow growing and have a high age at maturity. These characteristics make them particularly vulnerable to high levels of fishing mortality. The Northeast Atlantic stock is considered to be depleted. The species is assessed as Critically Endangered by IUCN and has been recently added to the OSPAR list of threatened and/or declining species and habitats.

Squid, Argentine short fin

The Chinese Common squid are a high value species, sold fresh, frozen, dried or processed into hoods and rings or sashimi for the Japanese sushi market. Squid has quite a bland taste so needs other flavourings to perk it up.
Squid is a mollusc related to octopus and cuttlefish. Characterised by a large, fleshy body (mantle), there are more than 300 different types of squid around the world but the most common species eaten in the UK are the European and the Atlantic squid.
Squid plays an important role in oceanic and coastal food webs and is removed from the sea before it has spawned (females die after spawning, though males may live to breed for a second year). Squid is also an important bait species for catching species such as tuna.
Squid fisheries around the world exhibit considerable variations in annual catch, mainly as a result of large fluctuations in annual abundance that appear to be environmentally driven. Fluctuating abundance together with their rapid growth and short life cycle means precise stock information is not available. Squid plays an important role in oceanic and coastal food webs and, without appropriate management, deliberately targeted industrial-scale fisheries have the capacity to remove significant quantities from the sea before they have spawned (it dies after spawning). Fisheries in UK waters tend to be small, seasonal, non-targeted and squid (Loligo forbesi and Loligo vulgaris) is generally taken as bycatch in trawl fisheries for nephrops and other demersal whitefish species. Check which area the squid is from as it may have been caught in an area where whitefish such as cod or whiting are unsustainably fished. A more selective method of fishing for squid is by jigging. An example of such a fishery in the UK is the Sennan Cove squid fishery in Cornwall, where fishermen go out in small punts and fish for squid using jigs, a method of fishing similar to that of hand lining.

In particular, species native to the Caspian Sea and rivers feeding it have suffered sturgeon habitat loss, destruction of breeding grounds, pollution and mismanaged fisheries. The value of wild sturgeon caviar is so high that there is a substantial illegal fishery for sturgeon that is completely unregulated. Avoid eating wild sturgeon. Due to the lucrative market and demand for caviar, sturgeon aquaculture developed. As wild sturgeon are so depleted, farmed caviar is a better choice. With sturgeon farming there is no dependence on wild fish for broodstock as all fish are bred in hatcheries. Most sturgeon farming in Europe takes place in France.

Whilst there are measures in use to reduce these impacts, more needs to be done to ensure they are effective and that impacts to these species are minimised.
