Calcium and phosphorous contents of abdomen and cheliped muscles of juvenile, male
and female Macrobrchium nobilii were determined from field collected samples. In all
the three groups calcium concentration was higher in chelipeds while the phosphorous
content was more in abdomen muscles than in the chelipeds. However between three
groups the calcium content varied significantly both in the abdomen and cheliped
muscles (P<O.OOl) while the phosphorous content differed (P<O.OS) only in abdomen
muscles
