Abstract
Fresh water fish, Labeo rohita was exposed to sublethal
concentrations (0.25, 0.5 and 1.0 mg l-1) of the
organophosphorus insecticide, methyl parathion
(MP) for 15, 30 and 45 days. Aspartate and alanine
amino transferase activity increased with increasing
pesticide concentration, suggesting tissue damage
and muscular harm due to exposure to methyl
parathion. The increase in the activity of alkaline
phosphatase suggests an increase in lysosomal
mobilization and cell necrosis due to methyl
parathion toxicity. The results clearly indicate that
the organophosphorus insecticide methyl parathion
is toxic at sublethal level and it affects intermediary
metabolism of Labeo rohita.
