Frigate Tuna ( Auxis thazard ) is one of commercial production of large pelagic fish fisheries in Sibolga Waters. The high demand for this fish has led to large-scale fishing practices that can disrupt the balance of fish populations in nature. Therefore, the objectives of the present study were to determine the maximum sustainable potential (Maximum Sustainable Yield), optimum effort (f opt ), and to find out the level of utilization, effort and catch of Frigate Tuna allowed. The secondary data analysis was using the Fox model. The results showed that the sustainable potential (MSY) of Frigate Tuna resources from Sibolga Waters amounted to 7,664.108239 kg/year with f opt value was 2, 539.025526 trips/year. utilization rate over the past 5 years has an average value of 153.2106% and an effort rate of 123.01%. It is concluded that the utilization resource level of Frigate Tuna from Sibolga Waters has been overfishing.
