‘In the present work an attempt has been made to study the effect of an organochlorine (MeritAlpha or Prophenofos) and an organophosphate (Mardo orAlpha Cypermethrin) pesticides on changes in acid and alkaline phosphatases in brain, liver and mucles in a freshwater major carp, Catla catla (Ham.). In the present study the inhibition in the activities of all the enzymes, assayed were found to be increased with the increase in the exposure of pesticides. Mardo and Merit Alpha were equally sensitive to both acid and alkaline phosphatase. The details have been discussed in this paper.
The present work is an endeavour to study the toxic effects on certain biochemical constituents (such as total carbohydrate, total protein and total lipids) of Mardo (orAlpha cypermethrin, an organophosphate) and Merit Alpha (or prophenofos, an organochlorine) in hepatic and muscular tissues of Catla catla after chronically exposing (15 and 30 days) the fishes to the toxicant. These pesticides caused significant decrease in total carbohydrate, total protein and total lipid both in the muscle and liver tissues in the fresh water Indian major teleostean carp, Catla catla (Ham.). The reasons for such changes have been discussed in detail.
