The aim of this study was utilizing Kemin multi-enzyme in common carp (<em>Cyprinus carpio</em>) diet and investigating the impact on fish survival rate exposed to the lethal concentration of abamectin. For this purpose, 350 fish were divided into two experimental diets, containing 0 and 1000 mg Kemin kg<sup>-1</sup> of diets for 6 weeks and weighed end of this stage. Then, LC<sub>50</sub> of abamectin for fish dietary consumed Kemin multi-enzyme (treatment group) was determined with different concentrations of abamectin (0, 0.25, 0.5, 1, 2, 3, 6 mL L<sup>-1</sup>) for 96 hours; also, this testes were repeated for the other group (didn’t fed with Kemin multi-enzyme-control group). Analysis of the data showed significant difference between treatment and control groups in terms of fatalities (<em>p</em><0.05). Higher mortality was related to the Kemin multi-enzyme group and lower mortality related to control group. The 96h LC<sub>50</sub> of abamectin for<em> Cyprinus carpio</em> that were fed with Kemin multi-enzyme and control group were 0.369 and 1.205 mg L<sup>-1</sup>, respectly. However, there was significant different between weights of treatment (10.43±0.58 gr) in compared with control group (7.56±1.32 gr) at the end of 6 weeks. Results of this study showed that use of Kemin multi-enzyme although increase the fish growth, but due to its effects, such as high intestinal absorption levels, it can increase the toxicity of abamectin (as an example of popular pesticides) and mortality rate.
