Preliminary report of the Norwegian groundfish survey at Bear Island and west-Spitsbergen in the autumn 1985
This report describes the results from a stratified bottom trawl survey carried out in September/October 1985. The cod stock was dominated by the 1982 and the 1983 year classes. Also the 1984 year class recruited considerably to the area. The year classes 1982-1984 made up 84% of the total index in...
