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.
