Coley fish

Binomial name: Pollachius virens
Family: Gadidae
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Gadiformes
Genus: Pollachius
Species: P. virens

Common Name : Coley

Other names: Boston blue (separate from bluefish), Coalfish/coley, and Saithe in the UK, the young fish are called podleys in Scotland and northern England.

Habitat: Coley fish is found in Loch Etive, North Sea. It is common in the northern parts of the Northern Atlantic, including the Bay of Biscay and Palmas Altas Campus. Adults can typically live up to 16–20 years and grow to 100–120 cm but individuals up to 130 cm (51 in) and weigh up to 32 kg (71 lb) have been caught. Juveniles tend to be found close to shore, particularly in rocky areas, and tend to move out into deeper waters as they grow. The current IGFA All-Tackle World Record is 22.7 kg (50 lb) which was caught at Saltstraumen in Norway

This species can be separated from P. pollachius by looking at the relative lengths of the upper and lower jaws. P. pollachius has a longer underslung lower jaw while P. virens has approximately equal upper and lower jaw lengths. This gives a very different profile to the head. In general, P. pollachius is a brown or golden colour with a dark back while P. virens is bright silver with a very dark green back. P. virens generally appears to have relatively smaller eyes. The lateral line of P. pollachius has a noticeable kink over the pectoral fins while that of P. virens is straighter.

The flesh of coalfish (P. virens) is darkly coloured (hence the common name) while that of P. pollachius is similar to other members of the cod family. This dark colour in the fresh uncooked flesh may have led to the undeserved reputation of this fish as poor for eating.


A Coley belongs to the same family as cod and haddock, although it’s considered inferior. Generally speaking, coley is a good choice, as stocks are currently healthy and most are harvested sustainably.

Coley is one of the least expensive fish in the cod family and is a great sustainable substitute for cod or haddock in many recipes. Coley has a distinctive coal-coloured skin with a thick white line running laterally along its body; the belly fades to pale silv

Food Uses:
Coalfish is edible and has commercial value, although it is considerably less valuable than premium whitefish such as cod and haddock. To achieve a salmon-like orange color, it can be salted and smoked. In Germany, the fish is commonly sold as Seelachs (literally ‘sea salmon’), although it is not closely related to any salmon.

While a great deal of saithe consumed in Europe are caught in British waters, it is not a popular fish with consumers there. Most of the British saithe catch is thus exported to France, where it is widely eaten.

It is delicious, healthy, and much cheaper alternative to cod. Coley stocks are thought to be in good shape around the UK and fish are caught using low by-catch nets. Coley is one of the top choices for sustainable British fish. Hake: Hake has a similar light flesh to cod, but is much more flavourful.

Capelin Fish

Binomial name: Mallotus villosus
Family: Osmeridae
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Osmeriformes
Genus: Mallotus
Species: M. villosus

Common Names: Capelin or Caplin

Capelin have a circumpolar distribution throughout the arctic and subarctic regions of the world. In the northwestern Atlantic, they range from western Greenland and Hudson Bay in the north to Maine in the south and are most abundant around Newfoundland. Since the early 1990s, they have been observed in greater numbers in the southern Gulf of St. Lawrence and on the Scotian Shelf. In the eastern Atlantic, they are found from the Barents Sea to the coast of Norway, as well as in Icelandic coastal waters. In the Pacific, their range stretches from the Juan de Fuca Strait north along Alaska and across the Bering Sea to Siberia. From there, their range extends south, around Japan and toward Korea. Some stocks of capelin spend the bulk of their lives offshore, moving inshore only to spawn on beaches, while other stocks live their entire lives offshore, spawning on the bottom in deep water such as in the Barents Sea, in Icelandic waters, and on the Southeast Shoal of the Grand Bank.

Capelin are small, slender fish that closely resemble smelt. They have a pointed snout with a slightly protruding lower jaw, a large dorsal fin and a small adipose fin behind it. They are silvery under their lateral line and green or olive-green above it, and their underside is silvery-white. During the spawning season, capelin exhibit sexual dimorphism, which means the head and back of males become darker; their pectoral, pelvic and anal fins are well-developed compared to females; and males have ‘spawning ridges’ consisting of a row of elongated scales just above the lateral line on either side of the body. Mature capelin are generally between 13 and 20 centimetres long, with the largest male found in Newfoundland waters at 25 centimetres long. Mature capelin can weigh as much as 40 and 45 grams, and rarely live longer than five years.


Food Uses:
Caplin fish is eaten in varius ways.Fried or rosted caplin is very tasty.

Possible health benefits of eating caplin;

  1. A rich source of high-quality protein
  2. A good source of selenium, a mineral that acts as a powerful antioxidant in your body

3.Omega-3 fats are polyunsaturated fats with many powerful health benefits.

4.Because capelin is a small forage fish, it tends to be much lower in mercury than larger fish like mackerel and swordfish.

Other Uses:
Commercially, capelin is used for fish meal and oil industry products, but is also appreciated as food. The flesh is agreeable in flavor, resembling herring. Capelin roe (masago) is considered a high-value product.

Known Hazards: Since it is a seafood , those who are allergic to fish and shellfish should avoid it.

It is dark brown in color, grading to white on the belly with two darker brown horizontal bands on the flanks. The stripes are more prominent during spawning, when they darken and the background color lightens.

The large pectoral fins are normally carried horizontally, perhaps helping the fish attain the profile of a shark. The first dorsal fin has six to nine independent, short, stout, sharp spines. The family name Rachycentridae, from the Greek words rhachis (“spine”) and kentron (“sting”), was inspired by these dorsal spines. The mature cobia has a forked, slightly lunated tail, which is usually dark brown. The fish lacks a swim bladder. The juvenile cobia is patterned with conspicuous bands of black and white and has a rounded tail. The largest cobia taken on rod and reel came from Shark Bay, Australia, and weighed 60 kg (135 lb).
