A trawl apparatus (1) equipped with a means for gathering seafood/biomass and conveying it to a seafood/biomass receiving vessel (3). The trawl (1) is equipped with an elongate, preferably rigid or flexible collecting cage (5) which at an inlet opening (5') is connected to the rear end (1') of the trawl, and from the inlet opening extends into a second portion, defined by walls (9, 9'), roof (9'') and bottom (9' '') which have openings for straining water, and is terminated in a downstream portion (5''; 5'' '). A conveying hose - or pipe (4; 16, 16') for conveying seafood/biomass from the collecting cage (5) up to the vessel (3) opens into the downstream or aft portion (5''; 5'' ') of the cage (5) via a funnel (13; 17). Air or other fluid is supplied from the vessel (3) via a supply hose (6; 19) for injection into the conveying hose - or the pipe (4; 16), in order, by injector effect, to cause suction of the seafood/biomass from the collecting cage (5) to the vessel (3). The apparatus is particularly suitable for continuous conveyance of seafood/biomass from the trawl to the vessel (3) during prolonged trawling.
