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.
