Danish seining uses large nets and weighted ropes that are laid out on the seafloor. The net is attached on one end by a long rope to the fishing vessel, and the other end is attached to a buoy. The ropes are then pulled together, closing in on its catch while the vessel moves slowly.
Danish seining is indiscriminate as it catches large amounts of non-target species. It impacts the seafloor by dragging weighted lines across the seabed. Because the lines are dragged for short distances and aren’t too heavy, the benthic impact is said to be much less than for bottom trawling and dredging activity.
