  • Net-mouth inclined trawl-net apparatus
    Patent number: 8196334
    Abstract: A net-mouth inclined trawl-net apparatus includes a substantially rectangular frame and a trawl net attached to the frame. The trawl net is formed of an upper net, a lower net, and a pair of side nets, and the trawl net has a shape formed of a body part of a quadrangular trapezoid shape. Each of the side nets attached to the frame has a longer side and a shorter side as an upper side and a lower side, and a side of each side net defining a net-mouth edge defines a side-net front edge inclination angle relative to a bottom side of an isosceles trapezoid having the shorter side of the side net as a side of the isosceles trapezoid, so that the frame autonomously maintains an inclination angle relative to the vertical axis due to a flow resistance and a lift acting on the net.
