16.1.5 Rearing of juvenile crab

Once they metamorphose into post larvae, they can be transferred to rearing tanks. Rearing of postlarvae (juvenile crab) is done in tank having 5 cm deep sand in order to facilitate the burrowing of crabs. The PL are stocked @5-10 baby crabs/ m². They are fed on boiled molluscan meat @ 1-2 %. In this rearing tank they are grown to 4 g and 30 mm carapace width. The growth of these baby crabs depends on temperature and food available to them.
