Dietary beet molasses enhanced immunity system of common carp (Cyprinus carpio) exposed to copper nano oxide, CuO-NP

The present study conducted on evaluating the effects of feeding with molasses along with exposure to copper nanoparticles (CuO-NP) on blood, serum and mucus immunity indices of Cyprinus carpio. The results showed that the blood indices, serum and mucus immunity enhanced significantly compare to the control group (p<۰.۰۵). CuO-NP is a compound with sevral negative effects on blood, serum and mucus immunological indices of common carp. The findings of the present study revealed that molasssupplementation could alleviate the negative effects of nanocopper oxide exposure on: blood (Hemoglobin, Hematocrit, Mean Corpuscular Hemoglobin, Mean Corpuscular Volume, Monocyte, and Lymphocytes), serum (Total protein, Aspartate transaminase, Alkaline phosphatase), mucus (Lysozyme, Alkaline phosphatase) indices. Considering the desirable effects of beet molasses on the reduction or suppression of physiological effects of CuO-NP in common carp, using molass in rearing aquatic species diets could be suggested as a protective solution.
