Title: MORPHOMETERIC DIFFERENCE BETWEEN BLACKCHIN TILAPIA SAROTHERODON MELANOTHERON AND THE OTHER FIVE TILAPIAS REVEALED BY MULTIVARIATE STATISTICAL ANALYSIS
Abstract: The morphometeric differences between newly introduced blackchin tilapia and other five tilapias including Nile tilapia, Israel red tilapia, Taiwan red tilapia, blue tilapia and Zilii tilapia of our country were studied with cluster analysis, discriminant analysis and principal component analysis. The results showed: (1) The head length of blackchin tilapia is 35.4% of body length, belonging to the small-headed type. (2) Morphometeric differences between blackchin tilapia and other five tilapias are significant. Blackchin tilapia has greater head length, body depth, and body width than those of the other five. (3) In morphometeric relationship tree, blackchin tilapia forms a separate cluster. Among the five tilapias, Zilii tilapia is close to blue tilapia; Taiwan red tilapia is close to Israel red tilapia; Nile tilapia, blue tilapia and Taiwan red tilapia are close to each other.
