ABSTRACT

The role of aquatic rice field species in rural diets has been underestimated. These aquatic animals potentially supply most of the protein, carbohydrate and other nutrients that are needed by the villagers. In the present study investigated freshwater crab haemolymph contains more amounts of protein (289 ± 3.38 μg/ml), less amount of lipid (8.334 ± 0.04 μg/ml) and moderate amount of carbohydrate (12.33 ± 0.13 μg/ml). The quantitative analysis of the haemolymph shows the presence of 18 amino acids. Likewise 9 essential fatty acids were observed in the crude haemolymph of freshwater crab Paratelphusa hydrodromous.

Keywords: Freshwater crab, haemolymph, protein, lipids, amino acids, fatty acids.
