An 8‐week trial was conducted to determine the effects of total replacement of 12.9% fish oil (FO) with soybean oil (SBO), peanut oil (PNO), sunflower seed oil (SFSO), corn oil (CO) and canola oil (CNO) on growth performance, health status and fillet fatty acid composition of hybrid sturgeon (194.28 ± 0.14 g). Compared to the FO group, dietary SBO decreased growth performance (p < .05), increased serum glucose and hepatic lipid content (p < .05). No obvious adverse effects on growth performance and health status were observed in PNO, SFSO and CO groups (p > 0.05). The fish fed with CNO had increased growth performance (p < .05), reduced serum ALT, AST, LDL‐C (p < .05) and enhanced serum GSH‐Px, T‐AOC, and LZM, MPO, C4 (p < .05). The contents of C18:1n9, C18:2n6, and ∑n‐3 PUFA and ∑n‐6 PUFA in fillets showed a positive linear correlation with the diets (p < .05). In summary, PNO, SFSO and CO are probable alternative lipid sources to fully replace FO. Hybrid sturgeon prefers to use CNO as a lipid source with improved growth performance and health status. The fillet fatty acid composition mirrors the dietary fatty acid composition.

膳食脂质来源对杂交st鱼生长性能，健康状况和圆角脂肪酸组成的影响（Acipenser baeri Brandt♀×Acipenser schrenckii Brandt♂）

进行了为期8周的试验，以确定用大豆油（SBO），花生油（PNO），葵花籽油（SFSO），玉米油（CO）和低芥酸菜籽油完全替代12.9％鱼油（FO）的效果（CNO）对杂交st的生长性能，健康状况和圆角脂肪酸组成的影响（194.28±0.14 g）。与FO组相比，饮食中的SBO降低了生长性能（p  <.05），血清葡萄糖和肝脂质含量增加（p  <.05）。在PNO，SFSO和CO组中未观察到对生长性能和健康状况的明显不利影响（p  > 0.05）。饲喂CNO的鱼生长性能提高（p  <.05），血清ALT，AST，LDL-C降低（p <.05）和增强的血清GSH-Px，T-AOC和LZM，MPO，C4（p  <.05）。鱼片中C18：1n9，C18：2n6和∑n-3 PUFA和∑n-6 PUFA的含量与日粮呈线性正相关（p  <.05）。总之，PNO，SFSO和CO可能是完全替代FO的替代脂质来源。杂交st鱼更喜欢使用CNO作为脂质源，具有改善的生长性能和健康状况。圆角脂肪酸组成反映了饮食中的脂肪酸组成。
