This study examined the growth pattern, condition factor (K), length at first capture (Lc50), length at first maturity (Lm50), gonadosomatic index (GSI), and selection factor (SF) of the hard-lipped barb (Osteochilus hasselti CV) in Sungai Batang River, Indonesia. Fish were weekly purchased from local fishermen over a two-month period (April-May 2024). A total of 355 specimens were studied, consisting of 204 males and 151 females, with total lengths ranging from 60 to 190mm and weights from 2 to 91g. The fish exhibited an isometric growth (b = 2.98–3.04) and were in good condition, with a sex ratio of 1.4:1. The length-weight relationship was strongly positive (r = 0.9575–0.9863). No significant differences were observed in total length (TL), body weight (W), or the mean W/TL ratio between the sexes. However, females had higher mean values for body depth (BD), BD/TL ratio, and K value compared to males. The Lc50 was greater than the Lm50, indicating a high likelihood of spawning. The Lc50 and SF values were 116.5mm and 3.65, respectively, suggesting that the use of a 1.25-inch mesh size gillnet is suitable for fishing practices. A follow-up collection of fish samples was conducted three months later (June-August 2024) to investigate the maturity stages of both sexes and determine their GSI. Macroscopic morphological characteristics revealed that testes could be classified into four stages: immature, mature, ripe/spawning, and spent. Female ovaries were classified into five stages: immature, mature, ripe, spawning, and spent. The GSI values for males ranged from 1% to 10.52%, while those for females ranged from 1% to 13.46%. The findings of this study provide a valuable baseline for evidence-based fisheries management.
