Cytogenetic effect of agro-pesticides on sperm shape abnormality in Channa punctatus in vivo

Abstract

The objective of this study was to determine the associations of cytogenotoxic effect of agro pesticides on sperm head morphology. The quality of sperm from Channa punctatus fish was assessed to determine as a suitable indicator of the effects of pollution in freshwater. The fish was exposed in vivo to three different concentrations (MC,MC/2&MC/5) of eight pesticides (Dimethoate, Dichlorovos, chlorpyriphos and Malathion, Methylparathion, Fenvalerate, Cypermethrin and Cabaryl) belongs to Organophosphates, pyrethroid and Carbamate group in different time periods (5,10,15,20,25days). Sperm head analysis and tail used as simple bioindicator for monitoring aquatic pollution in Channa punctatus subjected to breeding soundness evaluation were designated as unsatisfactory solely on the basis of sperm morphology highlights its importance. Though insufficient data refrain us from significant statistical analysis but will play significant role in further research of cytogenotoxic and teratogenic end point of aquatic pollutants on male reproductive physiology in this species.
