研究了纳米硒（NanoSe）和纳米镁（NanoMg）对淡水养殖的亚洲鲈鱼幼鱼生长、体液免疫、血清生化和抗氧化能力的影响及其相互作用。将平均重量为32.78 +/-2.23 g的四组鱼喂食实验饮食之一6周：（a）对照（基础饮食）;（B）NanoSe（基础饮食+4 mg NanoSe/kg饮食）;（c）NanoMg（基础饮食+500 mg NanoMg/kg饮食）;和（d）组合（基础饮食+4 mg NanoSe/kg饮食+500 mg NanoMg/kg饮食）。饲喂添加NanoSe的饲料（NanoSe和组合）的鱼显示出更高的增重、特定生长率和摄食量。NanoSe和NanoMg的组合增强了免疫应答。此外，鱼喂养的组合饮食显示较高的血清丙氨酸转氨酶和天冬氨酸转氨酶水平，但较低的葡萄糖浓度。肝脏超氧化物歧化酶、谷胱甘肽过氧化物酶和过氧化氢酶的活性在各组之间没有差异，但肝脏丙二醛水平在添加NanoSe和/或NanoMg的饲料中较低。可以得出结论，NanoSe提高了生长性能; NanoSe和NanoMg的组合增强了体液免疫; NanoSe和/或NanoMg提高了亚洲鲈鱼的抗氧化能力。
This study was conducted to investigate effects of and interactions between nanoselenium (NanoSe) and nanomagnesium (NanoMg) on growth, humoral immunity, serum biochemistry and antioxidant capacity of juvenile Asian seabass Lates calcarifer reared in freshwater. Four groups of fish with an average weight of 32.78 +/- 2.23 g were fed one of the experimental diets for 6 weeks: (a) control (basal diet); (b) NanoSe (basal diet + 4 mg NanoSe/kg diet); (c) NanoMg (basal diet + 500 mg NanoMg/kg diet); and (d) combination (basal diet + 4 mg NanoSe/kg diet + 500 mg NanoMg/kg diet). Fish fed with NanoSe-supplemented diets (NanoSe and combination) showed higher weight gain, specific growth rate and feed intake. The combination of NanoSe and NanoMg enhanced the immune response. Also, fish fed on combination diet showed higher serum alanine aminotransferase and aspartate transaminase levels but lower glucose concentration. The activities of liver superoxide dismutase, glutathione peroxidase and catalase were not different among all groups, but liver malondialdehyde level was lower in fish fed diets supplemented with NanoSe and/or NanoMg. It could be concluded that NanoSe improved growth performance; the combination of both NanoSe and NanoMg enhanced humoral immunity; and NanoSe and/or NanoMg improved antioxidant capacity in Asian seabass.
