From 1972 to 1974, 6291 saithe were tagged and released on the Norwegian west coast between 59 N and 62 N. Before 1972, only 40 saithe have been tagged in the area, in 1956 and 1959, and these experiments were not extensive enough to produce significant results. Preliminary results of the tagging experiments in 1972 and 1973 were presented by Jakobsen (1975, 1976a, b). Subsequent recaptures from these experiments have been relatively few and have not added much new information. Therefore, only results of the experiments from 1974 are presented separately, whereas the older experiments are summarized.
