Abstract: Studies regarding the diets of large croaker (Pseudosciaena crocea) have dominated research in recent years. However, few literatures has documented the differences between the fatty acids profiles of large yellow croaker (LYC) fed with trash-fish, commercial and formulated diets. This paper aims to differentiate these three fish groups based on the principal component analysis (PCA) and non-metric multidimensional scaling (NMDS) techniques. Literature compilation of fatty acid profiles of large yellow croaker was encompassed all papers published from 14 studies and 51 fatty acid profiles. The findings showed that the cumulative percentage of variance accounted for PC1 and PC2 showed rather low proportion (52.1%) to total variance; therefore the PCA analysis resulted in the deficient intuition to differentiate the fatty acids profiles of LYC fed with different sources of diets. In contrast, NMDS could discriminate the fatty acids profiles of LYC fed with formulated and trash/commercial diets with the stress value of 0.164.
