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 < 0.05). 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, 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.

本研究旨在评估糖蜜喂养以及接触铜纳米颗粒（CuO-NP）对鲤鱼血液，血清和粘液免疫指数的影响。结果表明，与对照组相比，血液指标，血清和粘液免疫力明显增强（P <0.05）。CuO-NP是对鲤鱼的血液，血清和粘液免疫学指标具有严重负面影响的化合物。本研究的发现表明，糖蜜的补充可以减轻纳米铜氧化物暴露对以下方面的负面影响：血液（血红蛋白，血细胞比容，平均红细胞血红蛋白，平均红细胞体积，单核细胞，淋巴细胞），血清（总蛋白，天冬氨酸转氨酶，碱性磷酸酶） ，粘液（溶菌酶，碱性磷酸酶）指数。考虑到甜菜糖蜜对减少或抑制鲤鱼中CuO-NP的生理作用的理想作用，可以建议在养殖水生动物日粮中使用糖蜜作为保护措施。
