摘要/Abstract

摘要： 安徽省池州市地处长江中下游, 是我国乃至全球生物多样性的热点区域之一。针对该区域的鱼类多样性研究相对匮乏, 加之近年来长江流域鱼类分类学发生了显著变化, 诸如新物种的发现与描述、同物异名的修订以及属级分类单元的变动等, 使得目前仍缺乏对该区域鱼类多样性的系统性研究与总结。为此, 本研究于2023年9月至2024年9月对池州市通江支流的鱼类进行了实地调查, 结合历史记录和参照最新分类学研究进展, 本文更新了池州市主要通江支流鱼类物种名录。结果表明, 池州市主要通江支流共有鱼类136种, 隶属15目32科81属, 包括土著鱼类134种, 外来鱼类2种。物种组成以鲤形目鱼类为主; 鲴科和鮈科物种数目最多。物种更新名录包含了新记录种17个, 其中有1个外来种。本次鱼类物种更新名录中, 24个有效物种发生了分类学变更, 有20个历史记录物种被剔除。此外, 未采集到的种有50个, 表明这些鱼类的种群数量正急剧下降, 而这些鱼类分别具有洄游性、喜流性、喜贝性等独特的生态偏好, 说明池州市鱼类多样性正面临人为影响的严重威胁。本次名录的更新弥补了历史数据准确性方面的差距, 为池州市渔业资源的可持续管理和生物多样性保护战略提供了基础数据, 为渔业发展和生态恢复提供了决策依据。

Abstract

Aims: Located in the mid-lower reaches of the Yangtze River, Chizhou City is recognized as one of the biodiversity hotspots both in China and globally. Research on fish diversity in this region remains relatively limited. Significant revisions in fish taxonomy within the Yangtze River Basin in recent years—including new species described, old species resurrected, and changes in generic-level classifications—have resulted in a lack of systematic research of the fish diversity in this area. To this end, seasonal field surveys of fishes into major tributaries of Yangtze River in Chizhou were conducted to update the fish species checklist of Chizhou during September 2023 to September 2024.

Methods: Due to the complexity of the habitat types, numerous sampling methods were employed to collect the fish specimens. Gill nets and cages of various sizes are prepared for each habitat type to capture fish. Also, fish were collected from the markets in the study area to ensure that sufficient specimens were available. This study updates the fish species checklist of Chizhou by integrating field surveys, historical records, and recent taxonomic revisions for relevant fish groups.

Results: The updated checklist comprises 136 species belonging to 15 orders, 32 families, and 80 genera, including 134 native species and 2 non-native species. Cypriniformes dominated the taxonomic composition, with Xenocyprididae and Gobionidae being the most species-rich families. Seventeen newly recorded species (including 1 non-native taxa) were identified. Taxonomic alterations involved the removal of 20 outdated records and revisions for 24 valid species. Fifty historically documented but uncollected species have unique ecological preferences such as migratory species, rheophilic species, shellfish-dependent species during field surveys.

Conclusion: The species diversity of freshwater fish in Chizhou faces severe threat due to anthropogenic impacts. The updated checklist underscores gaps in historical data accuracy, and provides fundamental data for sustainable resource management and biodiversity conservation strategies in Chizhou, supporting informed decision-making for fisheries development and ecological restoration initiatives.
