Abstract
Improvements introduced in the construction of floating artifacts for dredge fishing of the class comprising a sweeping net of substantial bag shape that has an open mouth at one of its ends whose mouth has upper and lower edges when the net is brought to through the water with the mouth at the front end of the net said lower edge of the mouth being connected at each end thereof through a board to one of a pair of main drag cables said upper edge of the mouth being connected to one or more auxiliary tow cables connected to one of the main tow cables, said improvements being characterized in that the drag boards through which the main tow cables are connected to opposite ends of said lower edge of the mouth of the barrier are intended during trawling to separate relatively and move in a downward direction in the water so that a movement is applied opening of the aforementioned lower edge of the mouth of the network in both the lateral and descending directions, with the auxiliary cable dragging or the two auxiliary cables at the end thereof, away from the sweeper, connected in the case of an auxiliary cable to each one of said main drag cables or in the case of two auxiliary cables each to one of said main drag cables, the point of connection to the main drag cables being in each case on the opposite side of said sweeper board to said net and at a sufficient distance from said net to allow said auxiliary cable or cables during the drag to apply an upward force to said upper edge of said net mouth so that it is kept fully open during the drag and is also allowed to the net is dragged across the sea at a height that sets it free from the seabed.
