Md. Sherazul Islam and Tandra Rani

The larval were reared and examined the development features of the striped spiny eel, Mastacembalus pancalus in the aquarium condition. The PG induced larvae were reared in different water sources and recorded the average survival rate 31.5%. The transparent newly hatched larvae were 1.65±0.15 mm in length having with a large yolk sac and melanophores on the body. The yolk sac was completely disappeared on the 4th day and started to exogenous feeding. The pigmented eyes, gut and gills were prominent on the 5th day. The upper and lower jaw was well developed within 7-8 days. The dorsal fin and caudal fin were distinguished clearly within 9-11days and fins decorated with smooth fin ray within 18-25 days. Metamorphosis of the species completed in 35 days and the larvae resembled to their parents but the further development of the organs noticed until 45 days and onward while their length reached 18.21±1.65 mm.
