Effect of Mesh Size and Hanging Ratio Gillnet to the Local Marketable Size of Giant Trevally Caranx ignobilis

Abstract Gillnets are widely used by small-scale fishermen to catch giant travelly Caranx ignobilis in coastal waters, the dominant fish caught small size not according market size. The parameters of gillnet such as mesh and hanging ratio can optimize target purpose this study was analyze effect gillnets on local marketable for C . fishing experiment carried out floating net cages at Ambon Fisheries Training Extension Center (BPPP) from June August 2022. A Simple randomized experimental designed with a factorial pattern model. different were treatments, they 2.5, 3.0 3.5 inches (3 factors) consisted 70%, 50% 30% factors). population that middle class ranged 24.5 29.5 cm total length. There is an factor , where more effective than others. In addition, value affects market, 70%.
