Publication Abstract

The objective of this study was to evaluate the effect of commercial formulation of triazophos on
esterase activity in the liver, kidney, brain, blood and muscles of Catla catla, Labeo rohita and
Cirrhinus mrigala fingerlings. Toxicity of triazophos was tested in the fingerlings of major carps
following static bioassay and probit analysis. The fingerlings of C. catla, L. rohita and C. mrigala
were exposed to three sub lethal concentrations: 1/5th (0.97, 0.48, 0.32), 1/10th (1.33, 0.66, 0.44) and
1/15th (0.12, 0.06 and 0.04 mg/L) part of LC50 of triazophos in three replicates for 8 weeks. The
activity of cholinesterases (acetylcholinesterase and butyrylcholinesterase) was significantly
inhibited even at the lowest concentrations of triazophos in brain, blood, gills, muscle, kidneys and
liver. It has been concluded that cholinesterases in liver were more inhibited compared to those of
brain, kidney and muscles.
