摘要

Singkil泥炭沼泽地区目前面临着严重的问题，包括森林砍伐和土地转化为油棕种植园。这种情况威胁到生物多样性和遗传资源的丰富性，可能导致各种陆生和水生物种，包括鱼类群落的灭绝。虽然有关于Singkil泥炭沼泽鱼类的报道，但没有关于该地区鱼类遗传多样性的信息。因此，本研究旨在探索利用DNA条形码方法验证亚齐省Singkil泥炭沼泽地区鱼类的分类地位，并分析其多样性和遗传关系。共获得123个DNA序列，产生了88个单倍型，包括34个种，23个科，29个属。对不同种间的遗传距离进行了分析。结果表明，大菱鲆与黄菱鲆的遗传距离最接近，为4.04%，黑桃与刺丝弓形虫的遗传距离最高，为31.62%。单倍型多样性最高的是Cyclocheilichthys apoogon，有6个单倍型，最低的是Caranx tille， Oreochromis niloticus和Taenioides cirratus，分别只有1个单倍型。与分子遗传学相关的科学数据对有效的渔业资源管理至关重要。

DNA barcoding of fish from Singkil peat swamp waters of Aceh Province, Indonesia

Singkil peat swamp area is currently facing significant issues, including deforestation and the conversion of land into oil palm plantations. This situation threatens biodiversity and the wealth of genetic resources, potentially leading to the extinction of various terrestrial and aquatic species, including fish communities. Although there have been reports on the ichthyofauna in Singkil peat swamp, information regarding the genetic diversity of fish in this area is not available. Therefore, this study aimed to explore the use of DNA barcode method to validate the taxonomic status, as well as analyze the diversity and genetic relationships of fish found in Singkil peat swamp area, located in Aceh Province. A total of 123 DNA sequences were successfully obtained, leading to the generation of 88 haplotypes, comprising 34 species, 23 families, and 29 genera. The analysis of genetic distance was performed between various species. The results showed that the closest genetic distance of 4.04 % was between Ambassis macracanthus and Ambassis nalua, while the highest at 31.62 % was between Mystus nigriceps and Toxotes jaculatrix. Cyclocheilichthys apogon had the highest haplotype diversity with 6 haplotypes, while Caranx tille, Oreochromis niloticus, and Taenioides cirratus showed the lowest with 1 haplotype, respectively. Scientific data related to molecular genetics is crucial for effective fisheries resource management.

期刊介绍： Zoologischer Anzeiger - A Journal of Comparative Zoology is devoted to comparative zoology with a special emphasis on morphology, systematics, biogeography, and evolutionary biology targeting all metazoans, both modern and extinct. We also consider taxonomic submissions addressing a broader systematic and/or evolutionary context. The overall aim of the journal is to contribute to our understanding of the organismic world from an evolutionary perspective. The journal Zoologischer Anzeiger invites suggestions for special issues. Interested parties may contact one of the editors.
