Bioremedial effect of turmeric (Curcuma longa) on haematological and biochemical parameters against fenvalerate induced toxicity in air-breathing fish Clarias batrachus

Abstract

Indiscriminate use of insecticides has increased many folds in the recent times. Farmers for the better yield of crops, are widely utilising the pesticides. These pesticides through agricultural run offs have reached the surface water like ponds and has contaminated the fl ora and fauna of it. Fish is the animal which are extensively cultivated in these ponds. Humans are consuming these fi shes as food as they have high nutritious value. These contaminated fi sh if consumed by the human has caused various health hazards to humans. The present research work is therefore focused to know the bioremedial effect of turmeric on fenvalerate induced toxicity in fi sh Clarias batrachus.Fenvalerate EC 20% (pyrethroid) was administered directly in water contained in aquarium at the dose of 0.92 ppm and observed for 96 hours after the dose calculation through LC 50 . Thereafter, aqueous rhizome extract of Turmeric was administered orally, daily by gastric intubation method at the dose of 100 mg/Kg body weight per day for 15 days. The study reveals that after the exposure of fenvalerate, there was signifi cant damage at the haematological and biochemical levels in fi sh Clarias batrachus. But, after the administration of rhizome extract of turmeric, there was signifi cant normalisation in the haematological and biochemical levels in fi sh. This denotes that turmeric not only possesses ameliorating and rejuvenating property but also maintains the normal functioning of the body of the fi sh. Thus, it proves to be one of the best antidote against fenvalerate induced toxicity.

Possible ameliorative effect of dietary curcumin against water copper toxicity in Clarias gariepinus fish

“…Curcumin possesses dual antioxidant activity and acts through the scavenging reactive oxygen species (ROS) including superoxide and hydroxyl radicals due to its phenolic structure, and induces the upregulation of several endogenous cytoprotective and antioxidant proteins. It is also an effective lipid peroxidation inhibitor (Kumari and Paul, 2020).…”

Growth Rate and Chemical Muscle Composition of <i>Oreochromis niloticus</i> Fish Cultured in Drainage Water and Fed Antioxidant Supplemented Diet

“…The term antioxidant refers to a wide spectrum of compounds, which are able to donate electrons and neutralize free radicals, resulting in the prevention of cell injuries [14] [15] [16]. In consequence, the search for effective, nontoxic, natural compounds with antioxidant activity has been intensified in recent years [17] [18] [19] [20] [21].…”
