ABSTRACT

The growth parameters, mortality, exploitation and recruitment pattern of goldband Upeneus moluccensis in Dumanquilas Bay were determined from August 2019 to July 2020. A total of 840 samples caught by fish corral were collected from the fish port of Bualan, Kumalarang, Zamboanga del Sur. Growth was estimated using the ELEFAN 1 and the estimated parameters were L∞ = 18.8 cm and K = 0.76 yr-1 . Total natural and instantaneous rate of mortality values were Z = 4.58 yr-1 , M = 1.74 yr-1 , F = 2.84 yr-1 and the exploitation rate value of E was 0.62 yr-1 . The recruitment pattern of goldband Upeneus moluccensis suggests that this specie spawns all year round. Based on the results, goldband Upeneus moluccensis caught by fish corral in Dumanquilas Bay, from August 2019 to July 2020 was overexploited and that fishery resource management must be promulgated and implemented to address the depleting fishery resource.
