Abstract

With the advancement of technology and the development of agriculture, the use of pesticides in this industry has also increased. The aim of this study was to investigate the effects of Abamectin toxin on survival and intestinal tissue of Caspian Roach as one of the valuable species in the Caspian Sea. For this purpose, 126 fingerlings fish were exposed to a different level of Abamectin for 96 h. Data analyzed showed that there was a significant correlation between fish mortality rate and Abamectin concentrations. Histological assays showed some typical tissue damages such as vaculation, necrosis, bleeding, epithelial degeneration, the intestinal villi destruction, deformation, and destruction of epithelial cells. Moreover, some clinical signs occurred like increasing operculum movement, swimming near the water surface, anxiety, and death with open mouth. The results of the present study showed that Abamectin can have toxicity effects on Caspian roach, also to sub-lethal concentrations, leading to several tissue damages and reduced survival rate of fish.Graphical abstract
