| Summary: | construct the phylogenetic tree of Osteochilus spp and Cyclocheilichthys spp using Cytochrome C Oxidase
Subunit I (COI) gene and to study the genetic divergence of the Osteochilus spp and Cyclocheilichthys spp
using COI gene. Samples were collected from Batang Kerang, Balai Ringin, Serian using three-layered gill
net method. A total of three Cyclocheilichthys spp and one Osteochilus spp tissue samples were successfully
processed for DNA analysis. The obtained sequences were aligned and edited using MEGA 6.06 program. construct the phylogenetic tree of Osteochilus spp and Cyclocheilichthys spp using Cytochrome C Oxidase

processed for DNA analysis. The obtained sequences were aligned and edited using MEGA 6.06 program.
The genetic divergence was analysed using Kimura 2-parameter distances. Neighbor-Joining, Maximum-
Likelihood and Maximum-Parsimony trees were constructed to determine the phylogenetic relationships
between species. The genetic divergence between species ranged from 0 % (between C. apogon individuals)
to 0.163% (between O. vittatus and C. armatus). The phylogenetic analysis suggested that Cyclocheilichthys
spp and Osteochilus spp are of different genus. This study was able to determine the monophyletic of
Cyclocheilichthys spp and Osteochilus spp based on the COI gene. The genetic divergence was analysed using Kimura 2-parameter distances. Neighbor-Joining, Maximum-
