Zusammenfassung: | Gillnets are the fishing gear selected by Kendal fishermen particularly in small-scale artisanal fisheries because gillnets need relatively small capital, have easy operation, use medium- or small-sized fishing vessels, and are selective towards catches. Modifications were made by increasing the performance of the fishermen gillnet to get more economical fish catches. This study aims to technically analyze the modified gillnet on the catch composition. The study was conducted in Kendal waters in April 2019 with a 1 GT vessel using a comparative design with experimental fishing. The modified gillnet was a net made from PA multi-monofilament of 0.20 x 10 ply with 4-inch mesh size with the specifications of the mounted length of netting of 50 meters and the mounted height of netting of 5.9 m for one net with a hanging ratio of 0.55. Based on the paired sample t-test results, tcount value = 7.690 is greater than ttable (0.05) = 1.796. H0 is rejected and H1 which states that there is a difference in the number and weight of fish caught by the fishermen gillnet and the modified gillnet is accepted. Dominant species caught by the modified gillnet were Euthynnus affinis which were mostly allowable to catch both caught by the fishermen gillnet (51%) and the modified gillnet (95%) and Scromberomorus commersoni which were mostly not allowable to catch both caught by the fishermen gillnet (89%) and the modified gillnet (64%). |
