Abstract

The pesticide abamectin, which is often used in agriculture, poses a threat to aquatic animals. Though its toxicity to fish has not yet been fully understood. In this study, we used the comet assay to examine the effects of being subjected to various dosages of abamectin on the genotoxic impact of abamectin in Cyprinus carpio. During 10 days, common carp were exposed to three different doses of abamectin (0.3, 0.6, and 0.9 mg L-1 ) based on previously discovered levels in aquatic environments. Toward the completion of the investigation, the Comet assay was used to assess the damage frequency (%), Arbitrary unit (%), and Genetic damage index (%) in carp gill and liver cells. The greatest damage frequencies of % 74.333±0.577 and % 70.333±2.082 were significantly found in the 0.9 mg L-1 group in the gill and liver cells, respectively (P<0.001). Our results showed a considerable increase in DNA strand breaks in C. carpio after exposure to abamectin, suggesting the pesticide's capacity to be genotoxic to fish.
