Abstract: Pesticides deteriorate the normal function of vital organs of fishes and in case of high concentrations, it totally damaged those organs. Histological changes in gills, liver, heart, intestine and kidney of three common fish species (
Channa punctatus,
Heteropneustes fossilis and
Anabas testudineus) have been studies to observe the effect of Diazinon as it has become a very common pollutant in the aquatic environment. Six different concentrations (2.5. 5.0, 10.0, 15.0, 20.0 and 25.0 mg/l) of pesticide had been applied in the test aquaria (Chari) to experience the major alterations of the vital organs of the three treated species of fish. Lower concentrations (2.5 to 10.0 mg/l) had no remarkable effect on the treated organs, whereas, Curley gill lamellae, irregular blood vessels in the liver, muscle fiber destruction in heart, blended Submucosa and glomerular necrosis were found in
C. punctatus from 15.0 to 25.0 mg/l doses. Lamellar fusion, sinusoid vacuoles, fused villi and hemorrhagic renal tubules were observed in
H. fossilis and bent in secondary lamellae, irregular blood vessels in liver, fragmented muscle fiber in heart, ruptured villi as well as necrotic glomerular were noticed in
A. testudineus in the same doses of Diazinon. The present study demonstrated that pesticide (Diazinon) disrupted the normal function of the sensible organs of fishes by damaging them in different ways.
