Neutron Activation Analysis of the shells of the Jamaican marine spiny lobster, land crab, marine blue crab an the giant Malaysian fresh water prawn shows that they contain 42%, 70%, 65% and 47% calcium respectively, expressed as calcium carbonate. The digestion efficiently for extraction of calcium varies significantly; not only with species, but also with the strength of the acid used and the digestion time. Standard acid hydrolysis is not effective in removing all calcium compounds from the shells of some species of crustaceans. The inorganic composition of the shells has been partially characterized by Neutron Activation Analysis (NAA).....
