Nowadays, is a typical cultured fish in south China due to its resource decline in the Pearl River. Meanwhile, since antibiotics had been banned internationally, Chinese medical herbal plant serving as alternative to antibiotics has been adopted in aquaculture. In the present study, to ensure the health growth of . , extract of traditional medical herbal plant was dietary supplemented and a series experiments were performed, including growth performance determination, physiological/biochemical detection, nutrition analysis, histology analysis, and 16S rRNA amplicon sequencing. Growth performance enhancement was determined since the weight gain rate (WGR), specific growth rate (SGR), and condition factor (CF) of . increased as feeding inclusion . extract. Interestingly, the total content of muscle fatty acids ascended via supplementing . extract at middle level, in which group the activities of superoxide dismutase (SOD) and catalase (CAT) significantly increased and thus retarded the lipid peroxidation process (manifesting as malondialdehyde (MDA) content rising). Additionally, immune response and inflammatory reaction was stimulated in low and high level . extract added groups, indicating a suitable dosage of . extract benefited in safety production. Moreover, gut microbiota community varied hugely as daily supplementation . extract and the keystone species were tightly related to lipid transformation, which ultimately led to fatty acids composition variation. Our results confirmed that dietary supplementation . extract at the middle level (0.5‰, w/w) is suitable for serving as feed additive in healthful aquaculture of . .
如今，由于其在珠江的资源减少，[具体鱼类名称未给出]成为中国南方一种典型的养殖鱼类。与此同时，由于抗生素在国际上已被禁用，作为抗生素替代品的中国药用植物已被应用于水产养殖。在本研究中，为确保[具体鱼类名称未给出]的健康生长，在饲料中添加了传统药用植物[具体植物名称未给出]的提取物，并进行了一系列实验，包括生长性能测定、生理/生化检测、营养分析、组织学分析和16S rRNA扩增子测序。由于[具体鱼类名称未给出]的增重率（WGR）、特定生长率（SGR）和肥满度（CF）随着饲料中[具体植物名称未给出]提取物添加量的增加而提高，因此确定其生长性能得到了增强。有趣的是，通过中等水平添加[具体植物名称未给出]提取物，肌肉脂肪酸的总含量上升，在该组中，超氧化物歧化酶（SOD）和过氧化氢酶（CAT）的活性显著增加，从而延缓了脂质过氧化过程（表现为丙二醛（MDA）含量上升）。此外，在添加低水平和高水平[具体植物名称未给出]提取物的组中，免疫反应和炎症反应受到刺激，表明合适剂量的[具体植物名称未给出]提取物有利于安全生产。此外，随着每天添加[具体植物名称未给出]提取物，肠道微生物群落有很大变化，关键物种与脂质转化密切相关，最终导致脂肪酸组成发生变化。我们的结果证实，在饲料中中等水平（0.5‰，w/w）添加[具体植物名称未给出]提取物适用于[具体鱼类名称未给出]的健康水产养殖作为饲料添加剂。
