摘要:

鱼类是河流生态系统的重要组成部分, 对维系河流生态系统稳定性发挥关键作用。鱼类多样性作为评价河流环境变化的重要指标, 可以直接反映该地区河流生态系统的健康状况。南岭地区河流众多, 淡水鱼类多样性十分丰富, 但目前尚缺乏对此地区鱼类物种多样性及其地理分布的系统研究。本文基于历史文献资料和相关书籍(截至2024年1月10日), 系统整理了南岭地区鱼类物种组成信息。结果表明, 南岭地区共有淡水鱼类261种, 隶属11目29科121属。其中, 土著鱼类248种, 外来鱼类13种。南岭地区鱼类以鲤形目鲤科和爬鳅科鱼类为主, 分别占南岭地区鱼类总物种数的56.7%和7.3%; 受威胁鱼类共19种, 占南岭地区鱼类总物种数的7.3%, 有11种列入《国家重点保护野生动物名录》(2021), 有28种属于“国家重点保护经济水生动物”。南岭地区鱼类多样性正面临严峻挑战, 主要由于河流污染、水利设施开发和过度捕捞等人类活动的影响, 导致该地区受威胁物种和入侵物种比例上升。建议今后加强治理河流污染、保护鱼类栖息地、科学开展增殖放流等。本文整理所得的南岭地区鱼类物种名录可作为今后南岭地区鱼类生物多样性保护的参考依据。

Abstract

Aims Fish are an important component of river ecosystems, playing a significant role in maintaining their stability and functioning. Assessing fish biodiversity is important for understanding environmental changes and evaluating the overall health of river ecosystems. Despite the rich river network and diverse freshwater fish population in the Nanling region, comprehensive studies on fish diversity and distribution are still lacking.

Methods This study systematically compiles and analyzes data on fish species in the Nanling region from historical literature and relevant sources up to January 10, 2024.

Results The updated checklist identified 261 freshwater fish species, classified into 11 orders, 29 families, and 121 genera. Among these, 248 species were indigenous and 13 were aliens. The region’s fish fauna was dominated by Cyprinidae and Balitoridae, which accounted for 56.7% and 7.3% of the total species, respectively. Notably, 19 threatened species (7.3% of the total) were documented, with 11 of them listed in the List of State Key Protected Wild Animals (2021). Additionally, 28 species were classified as National Key Protected Economic Aquatic Animals.

Conclusion Fish diversity in the Nanling region faces significant challenges primarily due to human activities such as river pollution, hydraulic infrastructure development, and overfishing. These factors have escalated the prevalence of threatened and invasive species in the area. To mitigate these challenges, it is imperative to enhance river pollution control, safeguard fish habitats, and implement scientifically based stock enhancement programs in the future. This comprehensive inventory of fish species in the Nanling region provides a reference for future conservation efforts aimed at preserving fish biodiversity in this area.
