图5 鲤科6种鱼类肠道菌群与宿主生长性能及抗氧化能力的相关关系分析。细菌群落结构与(a)生长性能指标及(b)抗氧化指标的RDA图; 前40个优势菌属相对丰度与(c)生长性能及(d)抗氧化指标的Spearman等级相关性热图。生长性能指标: VSI, 脏体指数; CF, 肥满度。抗氧化指标: T-AOC, 总抗氧化能力; DPPH, 2,2-二苯基-1-苦基肼基(DPPH)自由基清除率; H2O2, 过氧化氢含量。鱼种: LY, 鲢; BY, 鳊; YY, 鳙; JY, 鲫; QZB, 翘嘴鲌; TTF, 团头鲂。* P < 0.05; ** P < 0.01; *** P < 0.001。

Fig. 5 Correlation analysis of gut microbiota with host growth performance and antioxidant capacity in six cyprinid fish species. Constrained ordination plots from redundancy analysis (RDA) showing the relationships between bacterial community structure and (a) growth performance or (b) antioxidant parameters. Heatmaps of Spearman’s rank correlation coefficients between the relative abundances of the top 40 bacterial genera and (c) growth performance or (d) antioxidant parameters. Growth parameters: VSI, viscerosomatic index; CF, Condition factor; Sex, Sex; Age, Age. Antioxidant parameters: T-AOC, Total antioxidant capacity; DPPH, 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging rate; H2O2, Hydrogen peroxide content. Fish species: LY, Hypophthalmichthys molitrix; BY, Parabramis pekinensis; YY, Aristichthys nobilis; JY, Carassius auratus; QZB, Culter alburnus; TTF, Megalobrama amblycephala. * P < 0.05; ** P < 0.01; *** P < 0.001.
