Merkeforsøk med sei i Nord-Norge nord for Lofoten 1970 - 1974

Abstract

In 1970-1974, 7913 saithe, predominantly immature, were tagged in northern Norway. By the end of 1976, 1204 tags (15.2 per cent) were reported recaptured. Recaptures of spawning saithe in the North Sea were more frequent than in earlier experiments, whereas recaptures at Iceland were much less frequent than previously recorded. This may be a result of the decline of the stock of Atlanto-Scandian herring which used to be an important source of food for the spawning saithe. A nearly identical presentation of the result of these experiments is given in English by JAKOBSEN (1978).
