Data Mining Evidences Variabilities in Glucose and Lipid Metabolism among Fish Strains: A Case Study on Three Genotypes of Gibel Carp Fed by Different Carbohydrate Sources

Figure 3

Principal component analysis (PCA) biplot of physiological responses from three gibel carp strains fed different dietary carbohydrate sources. (a) The PCA performed at the strain level. (b) The PCA performed at the carbohydrate source level. Arrows indicate the direction of increasing values for each variable. Colour coding indicates cluster membership determined by -means clustering based on their scores on the main PCA dimensions.
