Abstract

The 96 hour LC50 value of monocrotophos - a widely used organophosphate
pesticide in the paddy fields of Kerala on the juveniles of rohu and mrigal are
found to be 46.34 and 42.33 ppm respectively. It is seen that rohu is more resistant
than mrigal. Both rohu and mrigal can be recommended as potential candidates
for culture practices in the paddy-cum-fish culture systems, as they show high
pesticide tolerance. But further studies are required on the residue accumulation
and depuration in the body of these fishes
