Monofilament made bootom-set gill net proves more efficient along the Andhra coast

Abstract

Along the morthern part of the Andhra Pradesh coast, the conventionally used 'nylon vala' and 'joga vala' (bottom set gill nets) made of synthetic multifilament nylon yam have been replaced with 'naramu' (net made of-synthetic monofilament yarn) without any change in shape. The standard dimensions of the net are : length : 300-500 m, width : 4m for 'nylon vala' and 7.5 m for 'Joga vala and mesh : 50mm. Fishermen attach foot rope, head rope and sinkers to the machine made 'naramu' purchased from the market. It was the experience of the fishermen that the use of the new type of net increased the fish catch as well as their profit.
