Abstract

Abstract: At P. monodon hatchery at Chandrabhaga Coast (Konark), P. monodon seed production was taken up as a trial run during shut down period of hatchery in the rainy season due to sudden drop in salinity during 1997. Aim was that to standardize the seed production commercially during lean period. With little modification of the existing infrastructure production was taken up. Initial hindrance and constraints did not stand as obstacle by the management of experts. Production of hatchlings from 70% to 80% then stage1 larvae to Post-larvae above 50% has successfully produced commercially during 2005-2006. It was noticed during the trial run that when brooders reared at 0ppt to 5ppt salinity and larvae reared at 0ppt to12ppt sanity recovery of Post Larvae was very good. During the larval rearing, water quality management and feed management were managed meticulously.
