Abstract

Phosphamidon and monocrotophos are two widely used organophosphate pesticides
in the paddy fields of Kuttanad, the rice bowl of Kerala. Channa marulius is
an important food fish inhabiting the intricate canals and polders of Kuttanad.
The 48 hr LC50 values for monocrotophos and phosphamidon experimented with
the juveniles of the fishes with their fiducial ranges were worked out. Phosphamidon
was found to be more toxic (LC50 = 6.18ppm) than monocrotophos (LC50 =
28.52ppm) even though both are organophosphates and neurotoxic in action.
