Loddeundersøkelser i Barentshavet i juni og juli 1977

Abstract

During the period 4 June - 30 May a survey was made on the Barents Sea capelin stock with observations on its distribution, abundance and age composition. A much lower quantity of capelin was recorded on this cruise than expected, and the survey was therefore partly repeated in the period July 10-21. After the last cruise it was evident that the Barents Sea capelin stock was still in good condition, and the size of the fishable stock was approximately the same as the year before. Possible causes for the low estimate in June are briefly discussed, and distribution maps are given for capelin larvae and plankton in June.
