This fishing method is especially suitable for the capture of both flatfish and demersal round fish either scattered on or close to the bottom.
The boat seines consists basically of a conical netting body, two relatively long wings and a bag. An important component for the capture efficiency of boat seines is the long ropes extending from the wings, which are used to encircle a large area. As for Danish seining, keeping the rope into close contact with the bottom as long as possible during the hauling is a major advantage and, for this reason, special heavy ropes are normally used. Many Seine nets are very similar in design to Trawl nets. Frequently, however, the wings are longer than on trawl nets.
