| Abstract: | Summary Oxygen consumption of gill, brain and muscle tissues ofChanna striatus exhibits a clearcut circadian rhythm with a maximum uptake at 18.00 h. Metasystox exposure decreased the oxygen consumption of all tissues. Maximum reduction is noted in gill followed by brain and muscle. The peak period of oxygen consumption is also eliminated in the pesticide-treated fish.Acknowledgments. Prof. G. Sundara Rajulu is thanked for suggestions and UGC for financial assistance. |
