Morphometric variations of the Genus Barbonymus (Pisces, Cyprinidae) harvested from Aceh Waters, Indonesia

Abstract

The objective of the present study was to analyze the morphometric variations of the three presumed taxa within the Barbonymus group, namely B. gonionotus, referred to locally as naleh; B. schwanenfeldii, referred to locally as lampam-A; and Barbonymus sp. referred to locally as lampam-B. The naleh samples were collected from Nagan Raya District, while lampam-A and lampam-B were collected from Aceh Tamiang District, Indonesia. Traditional morphometric characters were measured in 150 fish samples (50 individuals of every taxon). The results of univariate (ANOVA) and multivariate (Discriminant function analysis, DFA) analyses showed that lampam-A and lampam-B have overlapping morphological characteristics, whereas naleh were distinctly different. Therefore, it is presumed that lampan A and lampan B are the same species of B. schwanenfeldii. It was concluded that the morphometric data indicated that there are two species of Barbonymus in Aceh waters, i.e., B. schwanenfeldii and B. gonionotus.
