Development trajectory of the gut microbiota in shrimps across age. (A) Unweighted UniFrac PCoA of gut microbiota based on the OTU data. Each point represents the mean principal coordinate (PC) score of all shrimps in a group at one-time point, and the error bar means the s.e.m. (B) Clustering of the gut microbiota based on the unweighted UniFrac distance calculated with multivariate analysis of variance (MANOVA). Red: control diet group, blue: krill meal group. Sample sizes are the same as Fig. 1. ***P < 0.001.
