Saithe tagging experiments on the Norwegian coast between 62°N and 67°N, 1971-1974

In 1971-1974, 5222 young saithe were tagged on the Norwegian coast between 62°N and 67°N. By the end of 1976, 622 (12.7 per cent) were reported recaptured. The results show an increasing tendency of a southward migration as the experiments are moved to the south. A 50-50 per cent distribution of recaptures north and south of the tagging area seems normally to occur in experiments at about 65° N. There has apparently been a change in the migration pattern since the mid-1950ies when recaptures indicated a basically northward migration from areas at about 63°N. A nearly identical presentation in English of the results of the experiments in 1971 - 1974 is given by JAKOBSEN (1978)
