Abstract:

Research conducted in the last decade clearely shows a significant presence of various pollutants in waterbodies such as pesticides, detergents and effluents from industries which lead to changes in the physiological and biochemical aspects of non-target aquatic organisms especially fish. Focusing on the harmful effects caused by these pollutants especially the synthetic pesticides scientists have formulated eco-friendly plant based biopesticides, the one most commonly known are the neem based biopesticides. A new plant based biopesticide – Derisom has been manufactured by scientists recently from Pongamia pinnata plant which is now being used in many agricultural fields. The present study is conducted to observe the haematological alterations caused in Cyprinus carpio on exposure to sub-lethal concentrations of biopesticide – Derisom. Various haematological parameters such as RBC, WBC, Hb, PCV, MCV, MCH, and MCHC were examined. The results obtained after the conduct of the study shows a significant variation in the haematological profile of fish exposed to sub-lethal concentrations of Derisom.
