Abstract
A study was conducted in a 77.6 ha perennial shrimp aquaculture farm at Vypeen island, Kerala, India to know the catch efficiency of gillnets in prawn filtration farms. Comparison of catch was made between six different mesh sizes, viz., 28, 32, 34, 36, 38, and 40 mm and the relative catch efficiency of twine sizes, polyamide monofilament 0.16 mm diameter and polyamide multifilament 210 x 1 x 2 and 210 x 1 x 3. Mesh size ranging from 32 to 36 mm showed better efficiency for total catch of prawn and fish together. PA multifilament gillnets caught more of Fenneropenaeus indicus, other shrimps and fish in terms of total weight.
