Abstract

The haemocytes found in the blood of crustaceans are the main mediators of host defense against infections in crustaceans. Glucose is the principal monosaccharides present in the haemolymph of crustaceans. Glucose is stored in the form of glycogen. The stored glycogen is utilized in moulting, adaptation to hypoxia and /or anoxia, osmoregulation and during fasting periods. The variation in glucose in the haemolympatic glucose seem to be related to the reproductive period of the species, food availability and degree of environmental exploration. These factors led to different metabolic adjustment in distinct species of crustaceans. In this study the biochemical glycogen analysis was estimated in the haemocytes of both male and female freshwater crabs Barytelphusa cunicularis. The results showed that the average carbohydrate per cells in females is significantly more than that of males(P˂ 0.5).
