Abstract
A tentative method for separating North Sea herring stocks is described. The total numbers of white skeletal muscle fibres were counted in transverse section at a point 35% of the total length from the tail. Counts in two successive years showed no significant difference in particular stocks. In five herring stocks the mean white fibre counts for 1969 and 1970 combined were as follows: Bank, 64409; Shetland, 51472; Downs, 40584; Blackwater, 33934 and Buchan, 44979. The method provides confirmatory evidence for the homogeneity of spawning stocks.Keywords
