| Abstract: The experiment was carried out to study the toxic effect of the herbicide Gold Topik (80EC) on survival and behavior of mosquito fish Gambusia holbrooki . The mean lethal concentration (LC50) and differences between concentrations were determined during 24 hrs exposure and been measured using ANOVA methods at significant level (P<0.005). Ascending concentrations of Gold Topik (80EC) (7.7 ,8.7 ,9.7 ,10.7 ,11.7 ,12.7 ,13.7 ,14.7 mg/l) were used to determine. The value of LC50 was 11.7 mg/l. The mortality rate was increased with increasing the concentrations. Results of present study showed some abnormal behaviors including erratic and irregular swimming , decrease the feeding intensity , in addition to loss balance and increase the movements of operculum ,these symptoms lead to death of fish. | ||
