基于环境DNA的调查和评估不仅高效、省时，而且对监测目标造成的伤害也较小。环境DNA已成为评估和监测水生生物的常用工具。本研究利用环境DNA对长江干流的鱼类资源进行了调查，并比较了春季和秋季两个季节鱼类的变化。结果显示，春季鉴定出13种鱼类，秋季鉴定出9种鱼类。 eDNA检出率较高的鱼类有：鲳鱼、黄鲫、鲤鱼、草鱼、黄鳝、棘齿鱼、蜥鮈鱼、虹鳟、鲻鱼、红齿鳅。春秋两季季节变化不显着，环境因素对两季鱼类组合的影响不同。本研究利用eDNA技术对长江干流春、秋季鱼类成分进行监测，为该地区渔业资源的长期管理和保护提供了新技术。当然，污染、数据库不足等问题是环境DNA目前的短板，这将是我们未来研究和研究的重点。
Surveys and assessments based on environmental DNA are not only efficient and time-saving, but also cause less harm to monitoring targets. Environmental DNA has become a common tool for the assessment and monitoring of aquatic organisms. In this study, we investigated fish resources in the Yangtze River mainstream using environmental DNA, and the variations in fish during two seasons (spring and autumn) were compared. The results showed that 13 species were identified in spring, and nine species of fish were identified in autumn. The fish with higher eDNA detection were Sinibotia superciliaris, Tachysurus fulvidraco, Cyprinus carpio, Ctenopharyngodon Idella, Monopterus albus, Acanthogobius hasta, Saurogobio dabryi, Oncorhynchus mykiss, Mugil cephalus, Odontamblyopus rubicundus. Seasonal variation between spring and autumn was not significant, and the environmental factors had different effects on fish assemblages during the two seasons. Our study used the eDNA technique to monitor the composition of fish in the spring and autumn in the Yangtze River mainstream, providing a new technology for the long-term management and protection of fishery resources in the region. Of course, problems such as pollution and insufficient databases are the current shortcomings of environmental DNA, which will be the focus of our future research and study.
