ABSTRACT

The animals required food & oxygen continuously for energy and to perform various metabolic activities. Thus digested food and oxygen should be transported to all the cells. This function is carried out with the help of body fluids. The arthropods possess the open type of circulatory system, which is presumably derived from the highly organized closed system of their annelids or pre-annelids ancestors. In most of the crustaceans the heart is dorsally placed inside the body. The blood fills up to the main body cavity. Which does not corresponds to a primitive coelomic space but to sinuses of cavities burrowed within the body tissues. Thus tissues are in direct contact with blood. In these animals the system of cavities should be considered as a haemocoel and the blood which fulfils the characters of a circulatory fluid and those of inertial lymph should be caused haemolymph. The pigment haemocyanin is found in the blood of most crustaceans hence it has light blue colour. The green resolution has increased the production utilization of various types of pesticides for increasing the agricultural productivity; the indiscriminate use of them has polluted the aquatic environment, because these pesticides ultimately find the way aquatic environment. These pesticides have been found to be extremely toxic not only to several aquatic biota including crustaceans (Reddy & Rao, 1986) and ultimately poisoning dual threat to mankind. Pollution of aquatic environment by a variety of toxic substances has been a major concern for humanity Present research work on comparatively study of effect of organochlorine and Organophosphate pesticides on heartbeat of fresh water female crab Barytelphusa guerini, which is discussed with result statically and graphically.
