The inability of the 0-group saithe survey to forecast the strenght of the year-classes entering the fishery

Abstract

An 0-group saithe trawl survey was conducted annually in the Norwegian Sea and outside the Norwegian coast north of 62"N in April-May 1985-1992. The survey aimed at covering the distribution of 0-group saithe in the open sea before the fish entered inshore waters. The yearclass strength of the saithe measured at this stage did not correspond to the strength of the yearclasses measured later when entering the fishery.
