| Description | Journal: Iop Conference Series: Earth and Environmental Science Production of tuna in Sabang on the last two years has decreased significantly. In 2015, for example, the number of tuna production was 6,124 tons per week, while in 2017 it fell to 5,200 tons per week, or decreased by around 15 percent. This study aimed to analyze the amount of biomass, catch, and effort of tuna in sustainable conditions in Sabang using a quantitative method and 11 years (2006-2016) time-series data. The data consisted of catches and inputs from each fishing gear per year during the observation period. The data were analyzed by the surplus production model that was processed using Excel and Shazam. The results showed that the sustainable and actual production function models of tuna in Sabang had trajectories with patterns that continued to increase during the observation period. The current level of production over the past few years has exceeded sustainable production, and if this condition continues, it is feared there will be overfishing and overcapacity. |
