Net assembly used for purse seine fishery

A net assembly used for purse seine fishery, which is mounted on a first vessel, dropped into seawater from the first vessel, and towed by a second vessel to surround and pull fish to capture fish, the net assembly comprising:

• a plurality of floats floating on a surface of seawater to provide buoyancy to the net assembly, and coupled to one another in a spaced manner in a lengthwise direction of the net assembly;
• a net combination of a plurality of nets disposed under the floats in an inter-coupled state, and sunken and deployed from the surface of seawater to surround and capture fish;
• a weight body extending along a lower end of the net combination to provide a sinking force by means of gravity to sink the net combination;
• and
• a purse wire extending along the net combination while being spaced apart from the weight body in a downward direction, and tightened by the first vessel to allow the net assembly to form a closed space below the surface of seawater,
• the net combination including a fish capture part which forms a longitudinal end of the net combination in the lengthwise direction, is first dropped into seawater, is towed by the second vessel and is hauled to capture a school of fish;
• a longitudinal end part which forms an end of the net combination opposite to the fish capture part in the lengthwise direction and is coupled to the first vessel;
• a body part which is disposed between the longitudinal end part and the fish capture part and forms a portion for surrounding fish;
• an upper end part which forms upper ends of the fish capture part, the body part and the longitudinal end part and is coupled to the floats;
• and a lower end part which forms lower ends of the fish capture part, the body part and the longitudinal end part and below which the weight body is coupled,
• wherein the fish capture part and the longitudinal end part are formed by combining the plurality of nets made of a nylon material, and wherein the body part, the upper end part and the lower end part are formed by combining the plurality of nets made of a polyester or high-density polyethylene material having a specific gravity of 1.3 to 1.4.
