Tilapia (Oreochromis niloticus) is one type of fish that has high economic value and is widely consumed by the community. Therefore, the growth and development of tilapia larvae need to be considered. This study aims to determine the growth and development of tilapia larvae. The parameters in this study were observations of total larval length (TL), daily growth rate (LPH), and morphology of tilapia larvae. This research was conducted for 30 days. Measurements of total length growth and morphological development of tilapia larvae were measured on days 1, 5, 10, 15, 20, 25 and 30 DAH (Days After Hatching). Data were analysed descriptively. The results of this study showed that the growth of tilapia larvae from day 1 to day 30 increased. The development of tilapia larvae in the yolk sac phase occurred on day 1-7 and the transition phase (from endogenous feeding to exogenous feeding) occurred on day 6-7 DAH, and on day 8 the yolk sac had been exhausted. The morphological development of tilapia larvae began to form completely on day 10 DAH. © The Authors, published by EDP Sciences.
