Abstract
Bigeye snapper (Lutjanus lutjanus) is a marine demersal fish that generally lives offshore up to 60 m depth. This study was conducted with the aim of analyzing the growth type and condition factors of L. lutjanus fish in non-volcanic hydrothermal areas in the shallow marine waters of Kolono Bay, South Konawe District. Fish sampling was conducted twice a month starting from March to May 2022. A total of 93 fish were caught using gill net gear with mesh sizes varying from 1, 1.5, 2, 2.5, 3 and 4 inches. The fish caught had a total length of 138 - 183 mm and weighed 31.7 - 77.9 g. The highest frequency was in the total length range. The highest frequency was in the total length range of 156 - 161 and 162 - 167 mm (females) and 150 - 155 mm (males). The length-weight relationship obtained was W = 0.0002 L 2.48. The value of b is 2.48 with a correlation r2 of 0.98. This indicates that the growth type of L. lutjanus studied is negative allometric (b < 3). Condition factor ranged from 0.48 - 1.62 with an average value 1.01. Condition factor values between males and females tend to be the same.
