The small redfish ( Sebastes viviparus ) is a marine fish very similar to the redfish ( Sebastes norvegicus ) known as edible fish. It comes in the northeast Atlantic from the coast of Norway (Tanafjord in Finnmark to Skagerrak), in the northern part of the North Sea , around Iceland , Rockall , the Faroe Islands and the Shetland Islands , on the coast of Scotland , the north of England and Ireland . It also occurs sporadically in the English Channel , on the south or east coast of Greenland and on Bear Island .

features

The redfish grows to a maximum of 35 centimeters in length, but usually stays at 25 to 30 centimeters in length. The maximum weight is one kilogram. It can be distinguished from the redfish mainly in that all the spines on the gill cover are directed backwards. Its color is bright red with three to four dark vertical bands on the flanks. In the lateral line row (SL) there are 70 to 80 scales, 11 to 13 scale rows are found between the end of the anal fin and the side line. The anal fin has three fin spines and usually seven soft rays.

Way of life

The small redfish lives as a schooling fish near the coast in a depth range of 50 to 300 meters. It prefers regions with rocky subsoil and in most cases stays ten to 150 meters above the sea floor. In summer he prefers deeper water. It feeds on small crustaceans and fish. Like all Sebastes species, it is viviparous. In summer 10,000 to 30,000 fish larvae 3 to 4 mm in length are born. The fry grow very slowly. They become sexually mature at an age of 10 to 15 years and a length of 20 cm.

use

The economic importance of the small redfish is low.
