Immigration and emigration of cod in the spawning areas of Lofoten and Møre
(ICES CM Documents;1984/G:48, Working paper, 1984)Abundance estimates of the spawning stock of north east Arctic cod have in recent years been given on the basis of acoustic surveys. Migration in and out of the surveyed areas during investigation has been considered as a ... -
The Effect of Gangion Floats on Bait-loss and Catch Rates in Longlining
(ICES CM Documents;1984/B:8, Working paper, 1984)The use of gangion floats will expectedly reduces bait loss and increase catch rates in bottom longlining. Two floats of 5- and 8 g buoyancy are tested through flume tank experiments, underwater observations in the field ... -
