Cod

From ArticleWorld


Cod is the common name for the genus of fish, ‘’Gadus’’. It is also used as the common name for many other fishes. A mild, flaky, low fat fish, cod has become very popular. It is one of the most common types of fish served, in the United Kingdom, as fish and chips.

Gadus species

Many species have been classified in this genus, however many have since been reclassified. In modern taxonomy, there are only three recognised species, the Atlantic cod (Gadus morhua), the Pacific cod (Gadus macrocephalus), and the Greenland cod (Gadus ogac). The common name cod is still used for many of the fishes no longer classified as such, but related to the Gadus genus, these include:

  • Arctic cod (Arctogadus glacialis)
  • East Siberian cod (Arctogadus borisovi)
  • Saffron cod (Eleginus gracilis)
  • Polar cod (Boreogadus saida)
  • Rock cod (Lotella rhacina)
  • Poor cod (Trisopterus minutus)
  • Pelagic cod (Melanonus gracilis)
  • Small-headed cod (Lepidion microcephalus)
  • Tadpole cod (Guttigadus globosus)
  • Eucla cod (Euclichthys polynemus)

Scrod

Scrod is another name for a young cod or haddock. Usually two pounds or less, split, and deboned. Used mostly in New England, it is a generic term referring to any white, edible fish, specifically the catch of the day.


[edit]

Unrelated species

Some fish are referred to as cod that are totally unrelated to the genus Gadus. A decline in stock has made Atlantic cod harder to catch, so replacements are marketed with word cod in the name. Some of these include:

  • Murray Cod (Maccullochella peelii peelii)
  • Eastern Freshwater Cod (Maccullochella ikei)
  • Mary River Cod (Maccullochella peelii mariensis)
  • Trout Cod (Maccullochella macquariensis)
  • Sleepy Cod (Oxyeleotris lineolatus)
  • Blue Cod (Parapercis colias)
