| چکیده | ||
| The aim of this study was utilizing Kemin multi-enzyme in common carp (Cyprinus carpio) diet and investigating its impact on fish survival rates exposed to the lethal concentration of abamectin. For this purpose, 42 fish were divided into two experimental diets, containing 0 and 1000 mg/kg of diets for 6 weeks. LC50 of abamectin for fish dietary consumed Kemin multi-Enzyme was determined with different concentrations of abamectin (0.25, 0.5, 1, 2, 3, 6 ml/l) for 96 hour. Then fish were exposed to 1.243 mg/liter abamectin. Analysis of the data showed significant difference between treatment and control groups in terms of fatalities (P <0.05). Higher mortality was related to the Kemin multi-enzyme group and lower mortality related to the control group. The 96h LC50 of abamectin for Cyprinus carpio (Treatment) was 0.369 mg/l. Results of this study showed that use of dietary Kemin multi-enzyme although increase the fish growth, but due to high intestinal absorption levels, it can increase the toxicity of abamectin and mortality rate in common carp. | ||
