While research analyzing the length-weight relationship, condition factor, and age estimation of *Decapterus russelli* (Indian scad) has been conducted extensively across various regions of Indonesia, biological information regarding the species in Bone Bolango Regency remains very limited. This study provides up-to-date baseline data on the growth characteristics and age structure of the *Decapterus russelli* population in the Gulf of Tomini, specifically from catches landed at the Inengo Fish Landing Base (PPI Inengo). The study was conducted from January to June 2026, with data collection taking place in February and March 2026. Fish samples were obtained from catches landed at PPI Inengo, Bone Bolango Regency, using a random sampling method with a total sample size of 800 fish. The measured length and weight data were analyzed using MS Excel and FiSAT II (Fisheries Stock Assessment Tools II) software. The results revealed that the length-weight relationship patterns for the 800 *Decapterus russelli* specimens at PPI Inengo varied by month: growth was negatively allometric in February (b = 2.687; R² = 0.8958) and positively allometric in March (b = 3.0690; R² = 0.7426). Bhattacharya analysis indicated rapid growth during the early phase, which slowed down as the fish approached a length of approximately 30 cm.
