摘要

Induced spawning of the freshwater spiny eel, Mastacembelus aculeatus was undertaken to obtain fertilized eggs for studying the embryonic development. The fertilized eggs were sticky, demersal and green in colour. The perivitelline space of fertilizedeggs was unequal. Several oil globules were visible on the yolk and sizes varied from 0.1-0.57 mm in diameter. First cleavage appeared at 50 min, producing two equal blastomeres. The size of blastomeres gets reduced as development proceeds. The fertilized egg took 4 h 10 min to reach morula stage. The hatching of egg started at 31 h 30 min and all the eggs hatched within 37-38 h at 28-29 deg C. The newly hatched yolksac larvae were 4-5 mm in length.
