Channa striata, locally known as "haruan", is economically important in fisheries and aquaculture industries in several Asian countries. DNA sequencing, based on a partial segment of the Cytochrome oxidase c subunit 1 (CO1) gene, was used to determine genetic variation in C. striata samples from four different populations on the west coast of Peninsular Malaysia. The highest nucleotide and haplotype diversities were observed in the Linggi population (π = 0.0067, h = 0.835), and the lowest in the Timah Tasoh population (π = 0.0008, h = 0.286). Apart from Kajang-Linggi, which was insignificant, F(ST) values were significant (p < 0.05) in all pairwise-population comparisons. Consequently, it is inferred that genetic structuring C. striata populations in this region was largely shaped by a common origin, with secondary influences from geographical factors and isolation.
波纹唇鱼，俗称“河鳗”，在亚洲多个国家的渔业和水产养殖业中具有重要的经济价值。本研究采用基于细胞色素氧化酶亚基 1（CO1）基因部分序列的 DNA 测序技术，对来自马来西亚半岛西海岸四个不同种群的波纹唇鱼样本进行遗传变异分析。林吉种群的核苷酸和单倍型多样性最高（π = 0.0067，h = 0.835），而提马索哈种群的核苷酸和单倍型多样性最低（π = 0.0008，h = 0.286）。除了卡江-林吉种群外，其他种群间的 F(ST)值均具有显著差异（p < 0.05）。因此，可以推断该地区的波纹唇鱼种群遗传结构主要是由共同起源形成的，地理因素和隔离也产生了次要影响。
