Pollack ( Pollachius pollachius )
The Pollack ( Pollachius pollachius ), also Pollack, Tartar or (barely still in use ), and wreck fish or Bright Yellow carbon Maul, is a fish of the cod family. The trivial name Pollack is ambiguous, sometimes including the Alaska pollock ( Theragra chalcogramma ) is called. In English-speaking also both of Pollack as well as the Köhler sold commercially under the name of saithe ( Pollachius virens) are called " pollack " or " pollock " means.
Distribution and habitat
The range of the species extends north-east Atlantic from Scandinavia, Iceland over the British Isles to Morocco. The Pollack is also native to the North Sea and the western Mediterranean. He settled in shelf regions, where he lives either pelagic or near the rocky bottom at depths to about 200 meters.
Features
The habit of Pollack similar to that of Koehler, top standing with a foot and three back - and two anal fins. Unlike its relatives the sidelines of Pollack however shows an arc-shaped curve over the pectoral fins. The mandible bears no Bartel. The back is black, brown or olive colored, the side line is greenish and the belly is a silvery gray color. In general, the Pollack reached a total length of about 75 inches, but occasionally a size of up to 130 centimeters possible.
Fins formula: Dorsal 1 11-14, 2 15-21 Dorsal, Dorsal 3 15-20, 1 24-34 Anal, Anal 2 16-21, 16-20 pectoral, ventral 6
Way of life
The swarms forming fish feed mainly on herring -like, deep-sea shrimp and sand eels. In the ongoing January to May breeding season the animals spawn at depths between 100 and 150 meters at water temperatures of between six and eight degrees Celsius. From the pelagic drifting eggs, the larvae hatch a week later. The first plankton -eating young fish spend their first two to three years of life in pelagic offshore, often thereby form swarms with charcoal burners of equal size. The Pollack has a life expectancy of about eight years.
Economic Importance
The meat of the Pollack is tasty but dry. Economically, it has little meaning, but often bycatch when fishing for cod and coalfish.
