Distribution, size and life cycle

Pouting are found predominantly in European waters, especially around the south and west of the British Isles and in Scandinavian waters, although they can also be found in the Mediterranean and along the north African coast. [2] They can be found across rocky and sandy seabeds with smaller specimens being found close to the shore and larger pouting being moving further offshore. The greatest depths at which pouting can be found is 300 metres. [3] Pouting are generally a small fish, seldom exceeding 30 centimetres in length, although rare specimens can reach almost double this length. Pouting can reproduce before they reach two years of age and grow rapidly, reaching around 15 centimetres in length by the end of their first year. Pouting are a relatively short lived species, with the average lifespan thought to be around four years. [4]

Feeding and diet

Pouting are scavengers which feed on the seabed. They forage for any food source they can find with marine worms, shellfish and dead fish all making up their diet. [4] Due to their small size pouting are a source of prey for large species such as cod, bass and conger eels.

Commercial value

Pouting were previously ignored as a commercial fish, with pouting that were inadvertently caught by trawlers being either discarded at sea or processed into fishmeal. [4] Captured pouting are unlikely to survive when discarded. [5] However, the decline in the stocks of whitefish species such as cod and haddock has seen pouting acquire a growing value as a commercial fish, [4] and they are now available both as whole fish from fishmongers and supermarkets and are also used in fish products such as fish fingers and ready meals. Due to their naturally short lifespan and early breeding age pouting are seen as a relatively sustainable fish to eat. [6]

Cod Common name for the demersal fish genus Gadus

Cod is the common name for the demersal fish genus Gadus, belonging to the family Gadidae. Cod is also used as part of the common name for a number of other fish species, and one species that belongs to genus Gadus is commonly not called cod.

Haddock Species of fish

The haddock is a saltwater ray-finned fish from the family Gadidae, the true cods. It is the only species in the monotypic genus Melanogrammus. It is found in the North Atlantic Ocean and associated seas where it is an important species for fisheries, especially in northern Europe where it is marketed fresh, frozen and smoked; smoked varieties include the Finnan haddie and the Arbroath smokie.

Trawling

Trawling is a method of fishing that involves pulling a fishing net through the water behind one or more boats. The net used for trawling is called a trawl. This principle requires netting bags which are towed through water to catch different species of fishes or sometimes targeted species. Trawls are often called towed gear or dragged gear.

Sand eel Common name for several species of fish

Sand eel or sandeel is the common name used for a considerable number of species of fish. While they are not true eels, they are eel-like in their appearance and can grow up to 30 centimetres (12 in) in length. Many species are found off the western coasts of Europe from Spain to Scotland, and in the Mediterranean and Baltic seas.

Blue cod Species of fish

The New Zealand blue cod is a temperate marine fish of the family Pinguipedidae. It is also known variously as Boston blue cod, New Zealand cod, sand perch, or its Māori names rāwaru, pākirikiri and patutuki.

Poor cod Species of fish

The poor cod, Trisopterus minutus, is a temperate marine fish belonging to the cod family (Gadidae). It is red brown in colour and has a pronounced chin barbel. It may grow up to a length of 40 cm. It is usually found in small shoals at depths between 10 and 300 metres on muddy or sandy bottoms. Its distribution spans the eastern Atlantic, from Norwegian coasts to Portugal and along the Atlantic coast of Morocco; also in the Mediterranean. Spawning takes place towards the end of winter. They are often regarded as a mini species and are commonly confused with pouting as they have a similar appearance. They are often seen as a menace for anglers and have little commercial value and so are not currently at any risk of extinction.

Bottom trawling

Bottom trawling is trawling along the sea floor. It is also referred to as "dragging". The scientific community divides bottom trawling into benthic trawling and demersal trawling. Benthic trawling is towing a net at the very bottom of the ocean and demersal trawling is towing a net just above the benthic zone.

Common ling Species of fish

The common ling, also known as the white ling or simply the ling, is a large member of the family Lotidae, a group of cod-like fishes. It resembles the related rocklings, but it is much larger and has a single barbel. This species is unrelated to the pink ling, Genypterus blacodes, from the Southern Hemisphere. The common ling is found in the northern Atlantic, mainly off Europe, and into the Mediterranean Basin. It is an important quarry species for fisheries, especially in the northeastern Atlantic, although some doubts exist as the sustainability of the fisheries. As an edible species, it is eaten fresh, frozen, or dried, but also preserved in lye, while the roe is a delicacy in Spain.

Yellowspotted catshark Species of shark

The yellowspotted catshark is a rare catshark of the family Scyliorhinidae. It is found in the southeast Atlantic, from Lüderitz, Namibia to central Natal, South Africa, between latitudes 0° and 37° S. It can grow up to a length of about 1.22 metres. The reproduction of this catshark is oviparous.

Alaska pollock Species of fish

The Alaska pollock or walleye pollock is a marine fish species of the cod genus Gadus and family Gadidae. It is a semi-pelagic schooling fish widely distributed in the North Pacific, with largest concentrations found in the eastern Bering Sea.

Potato grouper Species of fish

The potato grouper, also called the potato cod or potato bass, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It has a wide Indo-Pacific distribution.

Fanray Species of cartilaginous fish

The fanray is a species of ray in the family Platyrhinidae that lives in the western Pacific Ocean. It typically grows to a length of 30–50 centimetres (12–20 in) and a weight of 200–500 grams (7.1–17.6 oz), with a brown upperside and a white underside. It eats fish and crustaceans and has poor mobility. Males live to age five and females to age twelve, with both sexes maturing between two and five years. The species is found in China, Japan, Taiwan, Korea, Vietnam, and possibly Indonesia, in waters shallower than 100 metres (330 ft). It is probable that its population is declining due to being caught as a bycatch.

Cod fisheries

Cod fisheries are fisheries for cod. Cod is the common name for fish of the genus Gadus, belonging to the family Gadidae, and this article is confined to three species that belong to this genus: the Atlantic cod, the Pacific cod and the Greenland cod. Although there is a fourth species of the cod genus Gadus, Alaska pollock, it is commonly not called cod and therefore currently not covered here.

Common dragonet Species of fish

The common dragonet is a species of dragonet which is widely distributed in the eastern North Atlantic where it is common near Europe from Norway and Iceland southwards. It is a demersal species that occurs over sand bottoms. It lives to a maximum age of around seven years. It is caught in bycatch by fisheries and is used in the aquarium trade.

Trisopterus esmarkii, the Norway pout, is a species of fish in the cod family. It is found in the Barents Sea, North Sea, Baltic Sea, off the coasts of Norway, Iceland, the British Isles and elsewhere in the northeast Atlantic Ocean. It prefers depths between 100 and 200 m (330–660 ft), but occurs from 50 to 300 m (160–980 ft). Norway pout can reach 35 cm (14 in), but are more common at around 19 cm (7.5 in).

Trisopterus is a genus of small cods native to the northeastern Atlantic Ocean including the Mediterranean Sea.

Electric pulse fishing

Electric pulse fishing is a fishing technique sometimes used in trawl fisheries which produces a limited electric field above the seabed to catch fish. The pulse trawl gear consists of a number of electrodes, attached to the gear in the tow direction, that emit short electric pulses. The electrodes replace the tickler chains that are used in traditional beam trawl fishery. The pulse trawl fishery is mainly aimed at flatfish like sole, with by-catch plaice. In addition, the pulse trawl gear is applied in shrimp fisheries on a limited scale. Technically, the use of electricity to catch fish is prohibited in European waters. However, the European Union is able to provide exemptions to this rule since 2007. These exemptions are now mainly used by Dutch and British trawlers in the North Sea.
