SEASONAL STRESS ON FATTY ACIDS IN COMMON CARP WITH RELATION TO ACETYL CHOLINE ESTERASE

Abstract

Summer season with 30⁰C is taken as control, where as rainy season with 20⁰C is taken as cold stress and winter season  with  15⁰C is taken as cold adaptation. During summer season (control) The Acetyl Choline Esterase Increases, fats decreases and fatty acids increases. The fatty acids are utilized by the fish for its strenuous activity  during summer. During Rainy, season due to cold stress the fats increases and fatty acids decreases. In winter season due to cold adaptation the fats decreases and fatty acids increases with regard to tissue variation during cold stress the fats is more and fatty acids are less in osmotic tissues and facts are less and fatty acids are more in non osmotic tissues. Less AchE is synthesized in non  osmotic tissues and more in osmotic tissues. In case of species variations during cold stress AchE is more in cyprinus carpio followed by labeo rohita and least in Catla Catla whereas, fats occurs invise versa.
