Impact of an Endocrine Disrupter, Carbaryl on the Fresh Water Fish Catla catla

Freshwater fish, Catla catla were subjected to endocrine disrupting compound (EDC), a carbamate pesticide (carbaryl) for an acute concentration. The median lethal concentration (LC₅₀) was 14.99 mg l^-lfor 24 h. Haematological parameters like red blood cell (RBC), white blood cell (WBC) haemoglobin (Hb), hematocrit (HCT), mean corpuscular haemoglobin (MCH), mean corpuscular volume (MCV) and mean corpuscular haemoglobin concentration (MCHC) was significantly altered in the carbaryl treated fish. The current study points that the pesticide carbaryl was toxic to freshwater fish and the results from the haematological parameters serve as the useful nonspecific biomarkers.
