Effects of Endosulfan 35% EC and Fenvalerate 20% EC on protein and aminotransferase activity in a freshwater fish Labeo rohita

Dr.K.Suneetha

The freshwater fish Labeo rohita was exposed to endosulfan and fenvalerate a synthetic pyrethroid. The LC50 values determined for endosulfan and fenvalerate at 24hrs were 0.6876 and 0.4749 μgl-1 respectively. The fish were exposed to lethal endosulfan 0.6876 and fenvalerate 0.4749 μgl-1 and sublethal concentrations of endosulfan 0.06876 and 0.04749 μgl-1 for 24hrs and 15days. Changes in the Total proteins and protein metabolic enzymes such as AAT and ALAT of vital organs such as brain, liver, gill, kidney and muscle were studied. The percent decrease of total proteins and percent increase in activities of AAT and ALAT were observed. more pronounced in the fenvalerate exposure than endosulfan
