In August-September 1983, selectivity experiments with Danish seine were carried out in northern Norway. Two commercial vessels were used and hauls with 110 mm and 135 mm mesh size were compared, using the alternate hauls method. A variance analysis was applied to the data, splitting the variance into a vessel, an area (station), and a selectivity component. The resulting selection factors were substantially higher for both cod and haddock than found in selectivity experiments in 1982, which were based on the covered cod-end method.
