<p>A net fabric for a trawl net formed by metal net legs and resistance plates. The metal net legs forming meshes are connected at their intersections to the resistance plates which resist the flow of water and these plates have curved surface and are provided with four or more devices for attaching said metal net legs around the peripheral edge thereof. The resistance plates make it possible to spread the trawl net vertically and horizontally and keep the shape thereof efficiently, and thus a net fabric which is very efficient when used in a trawl net can be provided utilizing the advantages of a metal net fabric with excellent durability and less water resistance in conjunction with its threatening effect to the fish.</p> |
