Abstract: This study was carried out to observe the stages of Pangasius sutchi embryo, incubation period and their larvae development. Fertilization rate for Pangasius sutchi is 87.59% and as for the hatching rate is 86.14%. The fertilized eggs are adhesive and spherical with a yellowish or greenish-brown egg capsule. The yolk sac is yellowish brown in color. The incubation period ranges from 24-35 h at a temperature 20-30 °c. The newly hatched larvae are transparent, lacking pigmentation and approximately between 3.111- 3.243 mm in length. Eye pigments and hearts started to work 12-15 hours after hatched. One day old pro-larvae, the mouth become well developed, barbules are elongated and look liked tiny thread. The yolk sac is fully absorbed during the 3 days old pro-larval stage. At the end, after two weeks the young fry is well developed, and is an adult appearance, that is measuring up to 26.765-26.910 mm in length. The survival rate for these larvae is 56% at the end of this experiment
