The aim of this study was to examine the composition, growth patterns and condition factors of yellowfin tuna caught in Bone Gulf waters. Sample collection was carried out in July – November 2018 at two stations, i.e., station 1 in Cimpu Luwu Regency and station 2 at the Lonrae Fish Landing Site, Bone Regency. At station 1, 10,366 individuals were caught, with an average size of 81.19 cm in length and of 14.43 kg in weight. Station 2 had a larger average size, i.e., 97.14 cm in length and 27.79 kg in weight. The results of the analysis of tuna growth patterns at station 1 and station 2 showed a value of b < 3, indicating negative allometric growth. This means that the weight gain of the species was slower than its length gain. The average value of the condition factor was 1.03±0.25 for station 1 and 1.07±43 for station 2. These values varied according to temporal variation and fish size. |
