<p>The capture of sharks in the Southern Indian Ocean of Java waters in Indonesia has become increasingly prevalent in recent years, posing risks of overfishing and potential extinction. Information regarding shark fisheries resources in the Indian Ocean Region in the coming years remains uncertain. This research assessed the condition of shark fisheries resources, considering utilization status and estimating production uncertainty of shark resources in the Indian Ocean, landed at the Samudra Fisheries Port (PPS) in Cilacap. The data collected consist of time-series production and fishing effort data from 2010 to 2020, which were landed at PPS Cilacap, as well as the composition of the types of captured fish. The data analysis employed in this study includes trend analysis of Catch Per Unit Effort (CPUE), utilization rate using the Schaefer surplus production model, and production uncertainty estimation using Monte Carlo simulations. Based on the utilization status, shark fisheries in the South Java Sea of the Indian Ocean fall within the optimal category, with an average utilization rate of 80.5%. This is evident from the decreasing trend in CPUE values with increasing fishing effort (f). Additionally, the high production uncertainty of shark resources, as indicated by Monte Carlo simulation forecasting patterns with an average annual production of 160.81 ton and a standard deviation of 790.92&#xa0;kg, underscores the need for stringent monitoring and supervision of shark fishing activities in the South Java Sea of the Indian Ocean to prevent overfishing. Regulations regarding shark fishing in the Southern Sea of Jawa of the Indian Ocean, Indonesia by local communities and local governments do not yet exist. However, shark fishery management is already in place at the national level through several regulations issued by the Ministry of Marine Affairs and Fisheries.</p>
