The Effect of Adathoda vasica Extract on the Haematology and Protein Content of Black Moor- Carassius auratus

Aquaculture systems are known stressful ecosystems. The stress is buffered by the culture fish via a number of behavioral, physiological or even genetic mechanisms. Adathoda vasica is a well known drug in the Ayurvedic and Unani system of medicine. The leaves contain a small amount of an essential oil, a crystalline acid and a white crystalline alkaloid vasicine. The present study attempts to throw some light on the effect of Adathoda vasica extract on the stress metabolic axis of the ornamental fish Carassius auratus (Black moor), a member of the family Cyprinidae. Elevated levels of TEC, TLC, protein and glycogen at 48 hours and 72 hours in both TD1 and TD2 treatments indicated an improvement in its growth. The fluctuations seen in the parameters studied indicate a positive impetus to the stress metabolism axis. It is possible to conclude on a positive note that Adathoda vasica methanolic extract dose have a growth promoting effect on Carassius auratus.
