Abstract :

The 120 fresh water crab Paratelphusa hydrodomas collected from nearby Bhavani River paddy fields, Tamilnadu, India. Healthy and active crab was taken for this study. Randomly 40 crabs were selected, sampled over a 3–months period. Normally the crab hemolymph was sterile (Haskell S., 1975, Stewart et al.).The hemolymph of 75% of all crabs sampled was found to be sterile. Only 25% of the crab hemolymph sample was found bacteria. Despite only bacteria containing individuals had very low amount of plasma protein (29.52±0.50) and Carbohydrate (6.65±0.37) in hemolymph. Three bacterial floras named as Pseudomonas, Bacillus and Staphyloccus were isolated from hemolymph and identified by using various biochemical tests. The present study supported by many researchers, but most of the studies were carried out only in marine crab and shrimp.
