Acute toxicity of diazinon and its effects on hematological parameters in the Indian carp, Cirrhinus mrigala (Hamilton)

Histopathological effects of Cyperdicot and vitamin E supplementation on selected organs of Clarias gariepinus (Burchell, 1822) reared in a tropical fish farm in Nigeria

“…Repeated opening and closing of the mouth and opercula covering accompanied by partially extended fin as observed in the present study could be due to clearance of the accumulated mucus debris in the gill region for proper breathing. Similar behavioral changes In C. gariepinus exposed to atrazine and chlorpyrifos (Nwani et al, 2013a) and Cirrhinus mrigala exposed to diazinon (Rauf and Arain, 2013) have been reported.…”

“…In the present study, the 96 h LC 50 values of Cyperdicot for the African catfish, C. gariepinus was found to be 0.80 mg/L. In general, toxicity of chemicals to aquatic organisms has been reported to be affected by temperature, pH, dissolved oxygen, size and age, strain of species, water quality, concentration and formulation of test chemicals (Nwani et al, 2010;Boran et al, 2012;Rauf and Arain, 2013). The magnitude of toxic effects of pesticides also depends on the length and weight, corporal surface/body weight ratio and breathing rate (Murty, 1986).…”

Effects of Vitamin E, Selenium and Vitamin C on Various Biomarkers Following Oxidative Stress Caused by Diazinon Exposure in Rainbow Trout

“…Diazinon is a commonly used pesticide and its existence in the fresh water reservoirs of Pakistan. Diazinon exposure at low concentrations produced significant changes in some hematological parameters of Indian carp (Cirrhinus mrigala) [14]. Diazinon is widely used in the Mekong river delta in Vietnam.…”

Acute toxicity and behavioral changes of Caspian kutum (Rutilus frisii Kutum Kamensky, 1991) and Caspian roach (Rutilus rutilus caspicus Jakowlew, 1870) exposed to the fungicide hinosan

“…Edifenphos (hinosan) is an organophosphate fungicide cutinase inhibitors that displays a specific antipenetrant action, but in practice its therapeutic activity may also involve direct fungitoxicity (Sisler, 1986). Several studies have been conducted on fish health effects of organophosphate fungicides and the removal process of these pesticides from water resources (Studnicka and Sopinska, 1983;Ahmad, 2011;Rauf and Arain, 2013;Shahbazi et al, 2015). In some species, the destructive actions of the toxin on the hepatic tissues have been reported, but the effects of these toxins on fish tissue are needed for further studies.…”
