Investigation of Acute Toxicity of Two Pesticides on Gold Fish, Carassius auratus gibelio

In this study that was done at Ornamental aquaculture center in Toushan village, acute toxicity test (LC50), NOEC and LOEC of Gold fish (Carassius auratus) were detected during exposure to diazinon and deltamethrin. These toxins are one of the most important organophosphate toxin in control of insects during agricultural and urban usage. Adult goldfish were exposed to different doses of toxins for 96h in group of 21 individuals and mortality rate was recorded. After 96h, there was 100% mortality at doses of 40, 80 ppm diazinon and 0.40 ppm deltamethrin. LC50-96h were 19±0.196 and 0.17±0.02 for diazinon and deltamethrin respectively.
