Abundance and distribution of postlarvae in the 0-group saithe survey in the north-east Arctic in 1985
From 11 May to 31 May 1985 a pelagic trawl survey was carried out outside the Norwegian coast north of 62° N. The purpose of this pilot survey was to examine the possibility of getting useful information about the year class strength of the North-East Arctic saithe before too many of the postlarvae...
