Abstract: Abstract The fishing of skipjack tuna (Katsuwonus pelamis) in the Flores Sea, Bulukumba Regency is currently conducted on an open-access basis. The majority of fishermen engage in the practice of catching fish without restriction, it is therefore imperative to gain an understanding of the biological aspects of skipjack tuna, including size structure, age groups, growth, and mortality rates, in order to effectively manage this resource. The objective of this study is to evaluate the stock condition and the level of utilization of skipjack tuna resources in the Flores Sea, Bulukumba Regency, South Sulawesi. The methods employed include survey techniques, stock condition analysis, potential (MSY) analysis, and an evaluation of the utilization level of skipjack tuna resources. The results of the study indicate that the skipjack tuna population in the Flores Sea is currently undergoing full exploitation. The fishing mortality rate 0.3930 per year is considerably higher than the natural mortality rate 0.2421 per year. This indicates that the primary cause of mortality is fishing activity. Furthermore, the utilization rate has also reached full exploitation. In light of these circumstances, it is imperative that fishermen refrain from augmenting the quantity of fishing apparatus at their disposal or embarking on fishing expeditions, in order to forestall the phenomenon of overfishing.
