Abstract

This study analyzed the population parameters of yellowtail fusilier (Caesio cuning) in Karimunjawa waters to inform strategies for sustainable management. Sampling was carried out over 13 months (July 2024-July 2025) at major fish trading centers on Karimunjawa and Kemujan Islands. A total of 1,583 individuals were measured for total length (TL, cm) and body weight (W, g) to estimate growth parameters, exploitation rates, and recruitment patterns. The results showed a negative allometric length–weight relationship. The length at first capture (Lc50%) was 19.8 cm TL, the growth coefficient (K) was 0.86 per year, and the exploitation rate (E) was 0.61, exceeding the optimal limit (E = 0.5). These values indicate overexploitation. Recruitment analysis revealed a continuous year-round pattern, with a peak between May and June. Overall, the findings confirm that the C. cuning population in Karimunjawa Islands is experiencing high fishing pressure.
