A morphometric study of species of Amblypharyngodon Bleeker, 1860 (Teleostei: cypriniformes: Cyprinidae) from the rivers of Western Ghats, Kerala


Sandhya ES, Chandran A

Morphological characters of Amblypharyngodon melettinus and Amblypharyngodon microlepis were analyzed using 48 morphometric characters between populations from three districts (Thrissur, Kottayam and Pathanamthitta) of Kerala, South - West coast of India. A total of 40 specimens from each station (120 individuals) were analyzed. Principal component analysis was performed involving the data on 33 morphometric characters of three population of Amblypharyngodon. The PCA yielded, 29 components, the first three of which remained significant and comprised 63.05% of total variance among body characters. The present observations based purely on traditional and truss morphometric characters revealed that the specimens of Amblypharyngodon from Pathanamthitta and Thrissur represent two population of A. melettinus and those from Vaikom (Kottayam) could be treated as a distinct population of A. microlepis.
