Abstract
Multivariate methods were used to compare meristic and morphometric characters of Ammodytes personatus from four populations in Korea (3) and Japan (1). ANCOVA showed the slopes of head length (Japan > East > South > West) and body depth (South > Japan > East > West) relative to total length to differ significantly among populations. Vertebrae and fin rays’ numbers differed significantly among populations, the former ranging between 64 and 67 (mode = 65, 66) in the East population, 62–67 (63, 64) in the West population and 62–64 (62, 63) in the South population in Korea. PCA and CDA, based on 14 morphometric characters, showed that scores plotted on axes 1-2 and 2-3 separated the three Korean populations but overlapped between the South and Japanese populations. These results suggest that the Korean A. personatus may comprise at least two populations.
