摘要

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.
