The aim of this study was to examine the reproduction characteristics of female bilih fish. Methodology: Sampling of fish was carried out at six stations determined based on the river characteristics and bilih fish habitat using bag net and cast net. Gonadosomatic index value varied from 0.12-31.70% with an average ranging between 5.70-9.16%. Results: Observation of 432 mature ovarians showed that the fecundity of bilih fish ranging between 8683-17824 eggs. Directly-measured oocyte diameter ranged from 70.6-877.8 μm, while histological-measured oocyte diameter ranged from 60.2-747.3 μm. Conclusion: Based on morphological and histological examinations, the gonad developmental stages of female bilih fish (ovarians) can be divided into five stages: Stage 1 (Immature), Stage II (Pre mature), Stage III (Maturing and Mature), Stage IV (Pre spent) and Stage V (Spent). Bilih fish spawning patterns are partial and the spawning peak occurred in August-September and February-March.]]>Kottelat, M., T. Whitten, S.N. Kartikasari and S.
