油菜籽亚麻荠经过基因工程改造，产生二十碳五烯酸（EPA）和二十二碳六烯酸（DHA），其水平与鱼油（FO）相似，我们将其作为虹鳟鱼饮食中的脂质来源进行了测试。测试了三种实验饮食，即FO对照、低水平转基因亚麻荠油（LCO）饮食（无FO，12.5 g/kg亚麻荠）和高水平转基因亚麻荠油（HCO）饮食（无FO，130 g/kg转基因亚麻荠）。鳟鱼（初始重量49.8 ± 11 g/鱼）喂养12周，并评估生长性能，脂肪酸含量（肌肉，肝脏，大脑和眼睛），和鱼片的感官特性。喂食LCO和HCO饮食的鱼的最终长度和重量高于喂食FO的鱼。增重、条件因子、特定生长率、采食量和饲料转化率无差异。与LCO饮食相比，在喂食HCO和FO饮食的鱼中肌肉组织中的EPA更高。化合物特异性稳定同位素分析显示，与喂食HCO的鱼中较轻的DHA相比，喂食FO饮食的虹鳟鱼储存了富含同位素的DHA。与FO组相比，来自HCO处理的鳟鱼鱼片质地更坚实，并且具有更高的橙子强度。
The oilseedCamelina sativawas genetically engineered to produce eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) at levels similar to fish oil (FO), which we tested as a lipid source in diets for rainbow trout. Three experimental diets were tested, a FO control, a low‐level transgenic camelina oil (LCO) diet (no FO with 12.5 g/kg camelina), and a high‐level transgenic camelina oil (HCO) diet (no FO with 130 g/kg transgenic camelina). Trout (initial weight 49.8 ± 11 g/fish) were fed for 12 weeks and were evaluated for growth performance, fatty acid content (muscle, liver, brain, and eye), and sensory properties of fillets. The final lengths and weights of fish fed LCO and HCO diets were higher compared to fish fed FO. There were no differences in weight gain, condition factor, specific growth rate, feed intake, and feed conversion ratio. EPA in muscle tissue was higher in fish fed HCO and FO diets compared to the LCO diet. Compound‐specific stable isotope analysis revealed that rainbow trout fed the FO diet stored isotopically enriched DHA compared to the lighter DHA in fish fed HCO. Trout fillets from the HCO treatment were firmer in texture and had a higher orange intensity compared to the FO group.
