Effect of permethrin and cypermethrin on oxygen consumption of a fresh water fish, H. fossilis

Abstract

Fish provide a high caloric diet to a large number of people all over the world but indiscriminate use of these pollutants has reduce fish growth synthetic pyrethroids may decrease nutritive value, as well as, there compounds may also rich to human body through fish flesh and will cause toxicity to human being also. Two sources of oxygen are potentially available to fishes while most use only dissolved oxygen; others have the ability to obtain oxygen from the atmosphere. All breathing fishes also use dissolved oxygen to some extent, under toxic condition, the oxygen supply becomes deficient and number of poisons become more toxic increasing the amount of poison being exposed to the animal. The fish breathe more rapidly and the amplitude of respiratory movement will increase. The result of the present study suggest that the altered rates of respiration of fresh water fish may serve as a rapid biological monitor of the pesticides exposure to important components of fresh water fish community.
