Principal coordinate analyses (PCoAs) between the microbiota of the four captive whitefish groups. (a) comparison between the four captive whitefish groups intestinal microbiota. (b) Comparison between the four whitefish groups intestinal microbiota in the mixed diet group. (c) Comparison between the four whitefish groups intestinal microbiota in the Artemia diet group. Ellipses of 95% confidence were done with dataEllips using R car package. Each whitefish species is represented by different symbols: dwarf (D♀×D♂), and normal (N♀×N♂) are represented by circle a cross respectively, and their ellipses are represented by continuous lines. The hybrid F1 N♀×D♂ and hybrid F1 D♀×N♂ are represented by the symbol × and □, respectively, and their ellipses are represented by dotted line. Dwarf and hybrid F1 D♀×N♂ are represented in red, whereas normal and hybrid F1 N♀×D♂ are represented in green
