Selective biochemical studies in a freshwater prawn,Macrobrachium nobilli(Crustecea: Palaemodinae)

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 (Pphosphorous content differed (Pabdomen muscles.
