Abstract
Mackerel is a small pelagic fish with high economic value. Many fishermen catch mackerel in large scale to get high profits, so there is a concern that overfishing will occur in the future. This research was conducted to determine the potential size of mackerel fish resources from a bioeconomic analysis that consists of biological aspects (MSY) and economic aspects (MEY) and as well as the magnitude of the actual and optimal levels of mackerel fish utilization. This research used Gordon Schaefer Bioeconomic Model and the Slovin method with 85% confidence level in taking respondents by purposive sampling. The optimal utilization rate of mackerel does not exceed the MSY value which was 3,208,9724 tonnes/year, and there is under the TAC value, which is 80% of the MSY value. The next management effort can take carried out based on bioeconomic analysis were a reduction in the level of effort by 3683 trips and a reduction in the number of catches by 1,861 tons so that the water resources will be sustainable again. This can be done by limiting the fishing fleet.
