Abstract: A method and an arrangement for trawling wherein trawl are bags positioned one above the other and towed by a single trawl vessel is disclosed. The bag(s) are continuously emptied of caught seafood/biomass via an injector assisted suction hose connected to a bottom end of the bag(s), and leading to the trawler vessel. In the case of two trawl bags, one above the other, the uppermost trawl bag is along the upper trawl opening portion equipped with a plurality of buoyancy bodies, and the lower trawl bag's lower trawl opening portion, at the outer ends, is equipped with weights or sinkers. Spreading of trawl opening(s) is effected either by otter boards, or a spreading member linked to the trawl opening portions. Tension lines pass from the outer ends of the upper trawl opening portion to the outermost positioned joining points for the trawl bags, and to the weights or sinkers.

Abstract: A trawl apparatus equipped with an element for gathering and conveying it to a seafood/biomass receiving vessel. The trawl has an elongate, collecting cage which at an inlet is connected to the rear end of the trawl, and from the inlet extends into a second portion, defined by walls, roof and bottom which have openings for straining water, and is terminated in a downstream portion. A conveying hose—or pipe for conveying seafood/biomass from the cage up to the vessel opens into the downstream portion of the cage via a funnel. Air is supplied from the vessel for injection into the conveying hose—or pipe, to cause suction of the seafood/biomass from the cage to the vessel.
