In this study, the effects of different feeds on fatty acid composition in the Chinese mitten crab (Eriocheir sinensis) were investigated. The fatty acid composition in the Chinese mitten crab was significantly correlated with the type of feed source provided. Differences between the feed groups pertained mainly five fatty acids: oleic acid, linoleic acid, palmitic acid, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The content of EPA and DHA was higher in the group of frozen trash fish than in the group of formulated feed. On the other hand, the content of oleic acid, linoleic acid and palmitic acid was higher in the formulated feed group than in the frozen trash fish group. There were significant differences in the nutritional value of the Chinese mitten crab reared under different feed sources, i.e. Chinese mitten crabs reared with the frozen trash fish feed were larger than those reared with the formulated feed, especially as regards the ω-3/ω-6 PUFA ratio and essential fatty acid levels.

饲料对中华绒螯蟹肌肉和性腺脂肪酸组成的影响()

本研究调查了不同饲料对中华绒螯蟹 (Eriocheir sinensis) 脂肪酸组成的影响。中华绒螯蟹中的脂肪酸组成与所提供的饲料来源类型显着相关。饲料组之间的差异主要涉及五种脂肪酸：油酸、亚油酸、棕榈酸、二十碳五烯酸（EPA）和二十二碳六烯酸（DHA）。冷冻杂鱼组EPA和DHA含量高于配合饲料组。另一方面，配合饲料组的油酸、亚油酸和棕榈酸含量高于冷冻杂鱼组。不同饲料来源饲养的中华绒螯蟹营养价值存在显着差异，即
