Abstract

In this study, morphometric characters and meristic counts were used to investigate the morphological variations of Cyclocheilichthys apogon and Cyclocheilichthys armatus. There are a total of 56 specimens; Cyclocheilichthys apogon from Batang Kerang (n = 20) and Wilma Plantation, Suai (n = 7) and Cyclocheilichthys armatus from Wilma Plantation, Suai (n = 29). The ANOVA analyses revealed 15 morphometric and 3 meristic characters that differentiated Cyclocheilichthys apogon from Cyclocheilichthys armatus. A PCA was performed on 15 log transformed morphometric measurements which the first two factors contributed to 82.5% of total variability. The ANOVA also shows small variations of C. apogon between these two different locations. Thus, the classification of Cyclocheilichthys apogon and Cyclocheilichthys armatus shows successful differentiated.
