Abstract: The adult shrimps, Penaeus monodon and Metapenaeus monoceros were induced to mature and spawn by eyestalk ablation. The larvae of both the species of shrimps were reared up to post larval stage on a diet of the phytoplankton, Chaetoceros calcitrans. The post larvae of M. monoceros were fed with artificial feeds only, whereas the post larvae of P. monodon were fed on small quantities of Artemia sp. in addition to artificial feed. After post larval stage, PL-20, the post-larvae were acclimatized to freshwater. Acclimatization was tried for different periods ranging between 2 and 20 days. The best survival rate was obtained for an acclimatization period of 5 days. Results obtained so far showed that the growth of P. monodon was significantly higher in freshwater. The methodologies of larval rearing, acclimatization and the results obtained on the growth of P. monodon in freshwater and seawater are described.
