摘要

西苏门答腊岛的圆螯鱼和圆螯鱼分别被称为Turiak和Catua鱼，是经济上重要的物种。这些鱼类种群的减少和生物信息的有限使得它们的遗传多样性和系统发育关系至关重要。通过分析从西苏门答腊岛采集的23个个体的线粒体DNA细胞色素b（Cyt b）和细胞色素氧化酶I（COI）基因的一部分测序，研究了遗传变异。系统发育分析揭示了环唇虫群的单系谱系，并支持贫血虫是环唇虫的同义词。C.armatus与C.janthochir亲缘关系密切，与C.apogon分离，序列差异为12.7-14.0%（Cytb）和9.4%-10.0%（COI）。apogon和armatus分别具有较低的单倍型多样性和遗传多样性。具有序列差异的群体内部和之间的遗传多样性分别为0.0-0.8%（Cyt b）和0.0%-0.7%（COI）。低水平的多样性可能意味着基因在种群内部和种群之间流动的可能性。目前的数据表明，所有种群都是一个单一的种群单位。目前的遗传信息对于建立有效的Turiak和Catua鱼类种群管理、保护和繁殖策略非常重要。

Phylogenetic Analysis of Cyclocheilichthys apogon and Cyclocheilichthys armatus (Fish: Cyprinidae) from West Sumatra

Cyclocheilichthys apogon (Beardless Barb fish) and Cyclocheilichthys armatus (Hihgfin Barb fish) in West Sumatra is known by the local name Turiak and Catua fish, respectively, are economically important species. Reducing populations and limited biological information about these fishes make their genetic diversity and phylogenetic relationships crucial. The genetic variation was investigated by analyzing the sequencing of a part of mitochondrial DNA Cytochrome b (Cyt b) and Cytochrome oxidase-I (COI) genes of 23 individuals collected from West Sumatra populations. Phylogenetic analysis revealed the monophyletic lineage of the Cyclocheilichthys group and supported Anematichthys as the synonym of Cyclocheilichthys. C. armatus was closely related to C. janthochir and separated from C. apogon with sequences divergence were 12.7-14.0% (Cyt b) and 9.4%-10.0% (COI). C. apogon and C. armatus have low haplotype diversity and genetic diversity, respectively. Genetic diversity within and among populations with sequences divergence was 0.0-0.8% (Cyt b) and 0.0%-0.7% (COI), respectively. The low-level diversity may signify a possibility of gene flow within and among populations. The current data suggests all populations as a single stock unit. Present genetic information is important to establishing effective population management, conservation, and breeding strategies for Turiak and Catua fish.
