Interesting about the cod

  • The cod or Gadidae describe a multi-species family of bony fish.
  • The most well-known representative of this family is the Cod or Gadus morhua, which is a coveted edible fish of great economic importance. He is considered one of the most important frogfish in the North Sea and Baltic Sea.
  • However, cod species also include other species of fish that are highly valued by humans for their bright, boneless and very firm meat.
  • Previously, cod was widely distributed in the temperate marine waters of the northern hemisphere. Overfishing affects many cod, which are important as food fish, but today as endangered species.
  • The range of the cod extends from the northern Atlantic Ocean to the Baltic Sea. Other species such as the Pacific cod and the Pacific pollack are, as their names have already revealed, found in the northern Pacific.
  • The cod preferably lives as a soil inhabitant at depths of up to six hundred meters and likes to stay close to the coast and in water temperatures of a maximum of ten degrees Celsius.
  • Some cod species also live in schools.
  • Depending on the species and range of the cod is either greenish, brownish, reddish or gray colored and shows a clear marbling.
  • All species share the elongated and spindle-shaped physique, the three dorsal fins and the two large anal fins. Also, the throaty ventral fins and the beard thread growing on the chin are clear signs of recognition.
  • Most cods are between forty and sixty centimeters long, but some species can reach body sizes of up to one and a half or two meters and a weight of well over forty kilograms. Cod is considered to be the largest cod representative.
  • Cods feed on worms, mollusks and crabs or plankton. Some species such as the cod or the Pacific pollack are predatory fish and catch haddock and herring.
  • Cods usually spawn just above the seabed, where the water has temperatures of no more than six degrees Celsius and a high concentration of oxygen.
  • The young fish live pelagic and develop only with increasing age to pure soil dwellers.
  • The maximum life expectancy of the cod is twenty years.
  • The well-known name "Alaskan salmon" is a misleading invention of the food industry to better market food produced from cod, such as fish fingers. Most of these are frozen foods made from the Pacific Pollack.
