1. Set Net

     The set net has the main structure consisting of two parts: Leaders, play ground and bag net. The leader net is usually 200 - 500 m long and has the height equal to the depth of the fishing ground. The net made of nylon multifilament of 210D/80 - 210D/90 with mesh size of 200 -250 mm. The leader net is set cross the movement direction of fish schools, whereas the playground net has one or two entries. Its structure is complicated to reduce the escape of fish from the playground. There is a lift net or dip net in the playground to collect fish. The mesh size of the playground net is 90 - 120 mm and smaller than that of the leader net. The mesh size of the net for collecting fish is much smaller and depends on the target species. The material of manufacture is nylon multifilament of 210D/9 - 210D/21.

    This is a stationary fishing gear. The net is set once during the fishing season. Its setting technique is very complicated. A system of anchors is used to keep the entrance net and the box net in a fixed position. When fish go into the box net, fishermen use purse nets (scoop net, lift net) to catch fish in the box net.

    The main target species of this fishing gear are mackerel, tuna and other pelagic fishes.
