Abstract

The calcium content in the exoskeleton of Penaeus indicus cultivated in a
brackishwaterpond was found between 4 and 15%, which was low compared to
other crustaceans. The haemolymph calcium was observed always at a higher level
than the calcium in the pond water. Calcium content of pond water and haemolymph
showed a direct relationship wiith the salinity. Relatively high levels of
calcium in muscle and low levels in exoskeleton were observed in June, the probable
reasons for this abrupt fall in the values are discussed.
