A Phenotype analysis of Neolissochilus sumatranus (Cyprinidae) which is an endemic species to Sumatra Island has been carried from five tributaries of Batang Toru based on 23 morphometric and 14 meristic characters. The result showed the significance of characters differentiation in morphometric characters but no differentiation in meristic characters detected. Using Kruskal Wallis Test and Mann-Whitney U Test, the characters which showed significantly different among population related to body width and body depth, as well as to fin and eye diameter. Plot Principal Component Analysis (PCA) indicated the distinction clearly for each population. Phenotype variation between N. sumatranus in North Sumatra proving the local adaptation ability of fishes in different environments, and it probably related to the ability of morphological plasticity.
