Abstract :Blood directly or indirectly takes part in almost all the physiological activities of fishes and is a good indicator of proper health. The external and internal factors have been found to influence the physiology of the body and their health is closely related with their blood parameters. In this study of C.punctatus, changes in some aspects of blood parameters have been studied and it was found that an increase in erythrocyte numbers, haemoglobin concentration and haematocrit values were found in the months of May, June & July, while a decrease was observed in the months of December and January. It indicated that the fish was found most active during summer months and inactive during winter months
Key words: Blood composition, Physiological indicator, Hematological parameter, Seasonal variation, C.punctatus.
