Ahmed Journal of Animal and Plant Sciences JAPS 20142014/12/01 24 6 Catla catla, Acute toxicity, Profenofos, Triazophos, Carbofuran, Carbaryl 1018-7081 NA <p>Pesticides are widely used in modern agriculture to aid in the production of high quality food. However, some pesticides have the potential to cause serious health and/or environmental damage. Organophosphates (OCP&rsquo;S) and carbamates can cause pollution in freshwater ecosystem, as well as having a significant effect on the health of fish. The acute effects of commercial formulation of triazophos, profenofos, carbofuran and carbaryl were determined in one of the indigenous fish species,&nbsp;<em>Catla catla</em>&nbsp;fingerlings. Pesticides were applied to fingerlings that had been grown under optimised standard conditions under a maintained static bioassay system.&nbsp; Probit analysis was used for the estimation of LC50 values, which were ascertained as 4.84, 0.19, 0.99 and 7.89 mg/L for triazophos, profenofos, carbofuran and carbaryl, respectively. 100% mortality of&nbsp;<em>Catla catla</em> was observed with a 2.8 mg/L dose of carbofuran at 96 hours with a significant difference. &nbsp;Acute toxic stress was noticed with subjects exhibiting behavioral intoxication, including suffocation, lying on the bottom, erratic swimming, lethargy and downward movements and gulping prior to mortality.&nbsp;</p> Catla catla, Acute toxicity, Profenofos, Triazophos, Carbofuran, Carbaryl Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2014-JAPS-257
