In order to further explain the fillet texture improvement of Yellow River carp (Cyprinus carpio) fed with faba bean (Vicia faba L.), a three-month rearing trial was conducted to investigate fatty acid composition, antioxidant capacity, myofiber development, collagen deposition and transcriptome in white muscle of two farmed carp groups (One was fed only faba bean, the other was fed commercial diet). As a strong oxidant, faba bean changed fatty acids composition in white muscle, especially DHA and EPA, up-regulated the levels of reactive oxygen species (ROS) and down-regulated major antioxidant enzyme activities in the hepatopancreas and white muscle. Through the analysis of transcriptome and subsequent verification analysis, we speculated that the increase of ROS led to the decrease of myofiber diameter and collagen metabolism. This study provides a theoretical basis for further understanding the regulation of faba bean on fillet texture characteristic of Yellow River carp.
为了进一步解释饲喂蚕豆（Vicia faba L.）对黄河鲤鱼（Cyprinus carpio）肌间刺品质的改善作用，进行了为期 3 个月的养殖试验，以研究两组养殖鲤鱼（一组仅饲喂蚕豆，另一组饲喂商业饲料）的白色肌肉中的脂肪酸组成、抗氧化能力、肌纤维发育、胶原蛋白沉积和转录组。作为一种强氧化剂，蚕豆改变了白色肌肉中的脂肪酸组成，特别是 DHA 和 EPA，同时上调了肝胰腺和白色肌肉中活性氧（ROS）的水平，并下调了主要抗氧化酶的活性。通过转录组分析和后续验证分析，我们推测 ROS 的增加导致肌纤维直径和胶原蛋白代谢减少。本研究为进一步了解蚕豆对黄河鲤鱼鱼片质地特性的调节作用提供了理论依据。
