MetadataShow full item record
Original versionThis report is not to be quoted without prior consultation with the General Secretary.
The surveys were carried out in June and in August - October. No estimates were obtained for 0-group capelin. 1 year old capeling are grossly underestimated in June. To a lesser extent this is also the case for older capelin. The estimates from the autumn surveys seem to be more reliable, and with respect to the spawning stock they correspond reasonable well with the estimates from tagging experiments and the trend of the catches.
