Five isonitrogenous and isoenergetic diets with soybean oil (SO), linseed oil (LO), algae oil from Schizochytrium sp. (AO), mixed oil (MO, SO:LO:AO = 1:1:1) and fish oil (FO; control group) were selected to feed juvenile Onychostoma macrolepis (initial weight 1.86 ± 0.07 g) for eight weeks. The results showed that in the LO and FO groups fish grew best. There was no significant difference in specific growth rate (SGR) and feed efficiency (FE) between the MO and FO groups (p > .05). The highest contents of 18:2n‐6, 18:3n‐3 and 22:6n‐3 in liver and muscle were found with the SO, LO and AO groups, respectively (p < .05). There appeared the highest malondialdehyde (MDA) content and the lowest superoxide dismutase (SOD) activity in the fish liver of the AO group. There appeared the highest concentrations of serum glucose (GLU), cholesterol (CHOL) and triglycerides (TG) in the SO group. The expressions of lipid anabolism genes were significantly up‐regulated by dietary SO and LO (p < .05). The expressions of lipid catabolism genes were significantly higher with the AO, MO and FO groups (p < .05). This study recommended that LO or MO as a better vegetable oil source for juvenile O. macrolepis.

三种鱼油替代鱼油对少年Onychostoma macrolepis生长，脂肪酸组成，抗氧化能力，血清参数和脂质代谢相关基因表达的影响

五个等氮和等能量饮食，分别来自大豆油（SO），亚麻籽油（LO）和来自Schizochytrium sp的藻类油。（AO），混合油（MO，SO：LO：AO = 1：1：1）和鱼油（FO;对照组）被选为幼小的Onychostoma macrolepis（初始重量1.86±0.07 g）喂养八周。结果表明，在LO和FO组中，鱼类生长最好。MO和FO组之间的比生长率（SGR）和饲料效率（FE）没有显着差异（p  > .05）。SO，LO和AO组分别在肝脏和肌肉中发现18：2n-6、18：3n-3和22：6n-3的最高含量（p <.05）。AO组鱼肝中丙二醛（MDA）含量最高，超氧化物歧化酶（SOD）活性最低。SO组出现了最高浓度的血清葡萄糖（GLU），胆固醇（CHOL）和甘油三酸酯（TG）。饮食中的SO和LO显着上调了脂质合成代谢基因的表达（p  <.05）。脂质分解代谢基因的表达在AO，MO和FO组中显着更高（p  <.05）。这项研究建议LO或MO作为幼年O. macrolepis的更好的植物油来源。
