Analisis Bioekonomi Dan Optimasi Pengelolaan Sumber Daya Ikan Layang Di Perairan Kabupaten Muna Sulawesi Tenggara (Bioeconomic Analysis and Resource Management Optimization of Mackerel Scad in Muna District, South East Sulawesi)

The resource utilization of mackerel scad (Decapterus spp.) has been increasing in Muna waters which will be able to reduce the fish stock and if it exceeds the carrying capacity, it will lead to "overfishing". This study aims to determine the level of production, fishing effort and the optimal economic chain, both biologically and economically, so that the management of fish resources in Muna waters can be carried out in a sustainable way. The study was conducted by the case study method. The analysis method used in this research is biotechnic; bioeconomy; static and dynamic optimization apprOAch of Walter-Hilbon (WH) estimation model. The results of the study provide an indicator that the mackerel scad in Muna waters has not experienced "overfishing" both biological and economic. MEY condition that is optimal for economic management will be achieved when the maximum effort as many as 213.734 trips, production amounted to 3.117,61 tons and maximum economic chain at IDR 33.434,41 billion. The amount of fishing effort in MSY condition within the model is 248.342 trips whereas the production amounted to 3.179,35 tons with the economic chain of IDR 32.557,81 billion. Results of biotechnic, bioeconomy, static and dynamic optimization showed that actual production is still below the sustainable production indicated by high production, effort and economic chain. Based on this analysis, the business effort of mackerel scad can be increased from the current fishing effort of 128.496 trips to 213.734 trips that will give the maximum economic chain and management of fish resources sustainably
