SOME ASPECTS OF CAPTIVE BREEDING BIOLOGY OF MUD CRAB, SCYLLA SERRATA IN BANGLADESH (Pages : 1 - 6)

The aquaculture of Scylla serrata has been practiced based primarily on capture and fattening of juvenile from the wild. Due to natural dependency to culture and environmental changes, made the species a threatened one. With the aim of bringing this species into culture system, bloodstock and embryonic development, and breeding technique of the mud crab S. serrata were investigated to develop hatchery technology in Bangladesh. Ten broods of S. serrata were collected from brood rearing pond to develop a crab breeding program in hatchery. Broods were spawned within three days and hatched within 7-8 days. The average fecundity was approximately 10,00000±70750 and the hatching rate was 5%. In embryonic development, only blastula stage and in larval development, newly hatch zoea stage was identified. The high mortality rate of the embryo and larvae due to might be low dose of disinfectant and improper transportation of eggs. However, present findings will be act as the baseline for the further research to establish a hatchery which is needed for the country to sustain coastal aquaculture against natural calamities as well as diseases outbreak in the shrimp farming.Download
