Abstract: 
In this study, the early development of Barbus sharpeyi larvae was surveyed through morphological changes and measuring total length, standard length, head length, thickness of larvae, eye diameter and snout length. The initial period of the larval life can be divided into 2 phases: endogenous and exogenous food sources. During the first three days of the larvae development, there was a gradual yolk sac reduction until its complete absorption at the end of third day, indicating the necessity of exogenous feeding. From the fourth to eleventh day, the final development of the heart, gill, air bladder, fins and intestine were observed. Total length of newly hatched larvae was 6.26mm and total length of fifteen days larvae was 8.35mm. The larval development of Barbus sharpeyi was similar to other Barbus species.
