Abstract

Grey bamboo shark, Chiloscyllium griseum was studied for maturity, development of egg case and hatching under captive condition. The live sharks were fed with a diet of chopped sardines. The female shark laid 27 egg cases over a period of 3 months. The egg cases were mostly released in pairs. They were almost oval in shape and equal in size. The time taken for successive release of egg cases ranged from 2 to 9 days. Duration of development of young ones inside the egg cases varied between 67-85 days. Sixty percent of the egg cases hatched. Male: Female ratio of the juvenile shark was 1:0.9. The mean length and weight of the shark at birth were 112mm and 5.0g respectively. The average monthly growth rate observed for the initial 60 days of rearing period was 25.0mm/8.35g.
