Abstract
Abstract: Problem statement: Presence of pesticide in streams and lakes is largely due to the runoff from agricultural fields. Pesticides are not highly selective but are generally toxic to many macrophytes, non-target organisms such as fish. Fish, generally accumulate contaminants from aquatic environments and have been largely used in food safety studies. Approach: The toxic effect of the insecticide abamectin on oxygen consumption and some biochemical characteristics (total protein, carbohydrate and cholesterol in liver, muscle, kidney and gills) of the tilapia fish (Oreochromis niloticus) were estimated. Results: The data shows that the rate of oxygen consumption was declined during all the exposure periods. On the other hand, all biochemical’s parameters were found to be decreased in all tissues on comparison with control. Conclusion: The results indicated the toxic nature of the insecticide abamectin.
Highlights
With rapid industrialization and increase in human population, the pollution of water bodies has become a universal phenomenon in the present day world (Bela and Prasad, 2008)
Presence of pesticide in streams and lakes is largely due to the runoff from agricultural fields and outfall from pesticide manufacturing factories (Anandkumar, 1988)
Arockia and Mitton (2006) investigated the effect of carbamate pesticide lannate on the biochemical components of the freshwater cichlid Oreochromis mossambicus (Peters); Venkateswara (2006) studied the toxic effects of novel organophosphorus insecticide (RPR-V) on certain biochemical parameters of euryhaline Wsh, Oreochromis mossambicus.; Shereena et al (2009) studied the effect of an organo phosphorous pesticides (Dimethoate) on oxygen consumption of the fish Tilapia Mossambica.; Impact of Cypermethrin and Ekalux on respiratory and some biochemical activities of a fresh water fish, Tilapia mossambica was studied by Logaswamy and Remia (2009); recently Patnaik (2010) studied the biochemical alterations Induced by Sevin in Clarias batrachus
Summary
With rapid industrialization and increase in human population, the pollution of water bodies has become a universal phenomenon in the present day world (Bela and Prasad, 2008). Pesticides are not highly selective but are generally toxic to many macrophytes, non-target organisms such as fish (Ayoola, 2008; Franklin et al 2010). Arockia and Mitton (2006) investigated the effect of carbamate pesticide lannate (methomy1) on the biochemical components of the freshwater cichlid Oreochromis mossambicus (Peters); Venkateswara (2006) studied the toxic effects of novel organophosphorus insecticide (RPR-V) on certain biochemical parameters of euryhaline Wsh, Oreochromis mossambicus.; Shereena et al (2009) studied the effect of an organo phosphorous pesticides (Dimethoate) on oxygen consumption of the fish Tilapia Mossambica.; Impact of Cypermethrin and Ekalux on respiratory and some biochemical activities of a fresh water fish, Tilapia mossambica was studied by Logaswamy and Remia (2009); recently Patnaik (2010) studied the biochemical alterations Induced by Sevin in Clarias batrachus Alterations in biochemical components as response to environmental stress are authenticated by many authors. Tilak et al (2001) studied the toxicity and effect of chloropyriphos to the freshwater fish Labeo rohita (Hamilton); Alkhail et al (2004) studied the toxicity and sub lethal effects on brain AChE and gill ATPases activity of tilapia fish, Oreochromis niloticus. Arockia and Mitton (2006) investigated the effect of carbamate pesticide lannate (methomy1) on the biochemical components of the freshwater cichlid Oreochromis mossambicus (Peters); Venkateswara (2006) studied the toxic effects of novel organophosphorus insecticide (RPR-V) on certain biochemical parameters of euryhaline Wsh, Oreochromis mossambicus.; Shereena et al (2009) studied the effect of an organo phosphorous pesticides (Dimethoate) on oxygen consumption of the fish Tilapia Mossambica.; Impact of Cypermethrin and Ekalux on respiratory and some biochemical activities of a fresh water fish, Tilapia mossambica was studied by Logaswamy and Remia (2009); recently Patnaik (2010) studied the biochemical alterations Induced by Sevin in Clarias batrachus
