Description Not Available
Mystus montanus eggs contain a relatively small yolk (1.0–1.2 mm) and are strongly adhesive. The egg envelope is thick and transparent. Embryos hatched 23.0–24.0 h after activation, and the incubation period was 23.0 h long. The circulatory system appeared early (at 17.75 h) and was characterized by a complex anastomosing vitelline system and by well-developed segmental vessels suggesting that M. montanus embryos can exploit available oxygen sources very efficiently. The post larvae were observed to have begun aerial respiration on the seventh-ninth day after hatching. After 20 days, the length of fry ranged 15.0–16.0 mm and resembled the adult in its external features. The length of fingerlings ranged from 25.0–30.0 mm
after 30 days, and their external features were just like those of an adult except that they were not sexually mature.
