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.
