Norwegian tagging experiments in the north-eastern North Sea and Skagerak, 1964 and 1965
Abstract
1. Norwegian herring tagging experiments carried out with internal
metal tags in Skagerak in 1964 and 1965 are described.
2. The returns from these taggings up to 31 October 1966 are reviewed
and factors affecting the losses of tags discussed.
3. Evidence for a movement of herring from Skagerak towards the Egersund
Bank-Coral Bank area and further westward to the Shetland
area was found.
4. Quantitative treatment of the recaptures from Norwegian reduction
plants equipped with magnets are dealt with and, tentative estimates
for the stock size in the Skagerak-Egersund Bank-Coral Bank areas
during the period November 1965-May 1966 are given.
