Abstract

Abstract. Due to the emergence of nanotechnology and the lack of awareness of the potential risks of these particles on the one hand and the beneficial effects of probiotics on aquatic animals on the other hand, the present study examined the effects of nano silver contamination on the physiological indices of carp fed fish Probiotics (bacterial bacteria), and periBitic (button mushroom) and synbiotic. The whole period of the experiment was 60 days, and the effective physico-chemical parameters were also controlled. In general, the fish were subjected to four experimental treatments and exposed to silver nanoparticles after six weeks of feeding with probiotic. The results of the analysis showed that M.C.H, M.C.H.C, MCV and hemoglobin had a significant difference with the control group (P <0.05). Probiotics have led to a reduction in these indexes. Hemoglobin increased in probiotic and synbiotic treatments and decreased in prebiotic treatment, which showed a significant difference with the control group (P <0.05). The amount of lymphocytes and eosinophils in probiotic treatment increased and the highest neutrophil content was observed in synbiotic treatment. Also, in relation to monocytes, the results showed that monocytes have the highest levels in the treatment of prebiotics. The nutritional supplements used in this study greatly contribute to improving the performance and resistance of common carp fish in the face of exposure to silver nanoparticles.
