An evaluation of the effect of a detergent on dissolved oxygen consumption rate of Anabas testudineus


Author(s): Divya S. Rajan

Abstract: Water is one of the nature’s most important gifts to mankind and that is very essential for the sustenance of life. Anabas testudineus, a common fresh water fish in Kerala was selected in the present study to determine the effect of detergent pollution on the oxygen consumption capacity of the fish in four different concentrations of a popular brand of detergent (sunlight).The amount of dissolved oxygen consumed by fishes were determined using Winkler’s method. The study demonstrated that dissolved oxygen consumption in Anabas testudineus increases with an increase in the concentration the of detergent. This is due to the stress caused by the detergent on the normal physiological activities of the fish. The study indicated that the draining out of domestic sewage containing detergents into the water bodies will adversely affect its aquatic fauna leading to cultural eutrophication. There is an urgent need of providing environmental education among the common people to avoid these thoughtless deliberate actions thereby aiming at sustainable development.
