Proximate Composition of Fresh Water Prawn Marobrachium Nipponenses and Crab Potamon sp. from al-Hawizah Marshes, South of Iraq

Abstract

The seasonal changes were studied in the chemical composition in muscle of caridean prawn Macrobrachium nipponenses and crab Potamon sp. from al-Hawizah marshes– south Iraq for the period from June 2016 to May 2017. that was found to be varied among the two different size groups examined. The results showed that there were clear seasonal differences in the chemical composition of both crustaceans, with the highest rate of protein 20.02% in species M. nipponenses in the spring, while the highest rate of fat for the same species 3.52% in winter, while the highest rate For the second species of protein 19.28% in the spring, while the highest rate of fat ratio in this species 2.64% in the autumn, and showed the moisture and ash ratios of the two species mentioned clear seasonal differences.In general, the protein content in muscle male and female of two crustaceans was higher in small size groups than in large size groups. The protein content in two sexes and size groups of two species were high.
