淮河荆涂峡鲤、长吻鮠国家级水产种质资源保护区鱼类群落结构特征及其与环境因子的关系
Fish community structure and environmental drivers in the National Aquatic Germplasm Resources Re-serve for Cyprinus carpio and Leiocassis longirostris in the Huaihe River
摘要
Abstract
To clarify the status of fishery resources and the relationships between fish community structure,biodi-versity,and environmental factors,we conducted a consecutive five-year(2019-2023)field monitoring in the National Aquatic Germplasm Reserve of Cyprinus carpio and Leiocassis longirostris(Jintu Gorge,Huaihe River).We analyzed the spatiotemporal differentiations of fish community and identified the key driving environmental fac-tors.The results showed that a total of 52 fish species were recorded,belonging to 5 orders,11 families,and 38 genera.Cypriniformes was the dominant group,accounting for 67.38％of the total species,with obvious interannual variations in dominant species.The Shannon diversity index,Pielou evenness index,Margalef richness index,and Simpson dominance index showed significant temporal differences but spatial convergence,and the overall biodiver-sity was at a medium level in the Huaihe River Basin.The abundance-biomass comparison(ABC)curve analysis indicated that fish community was unstable from 2019 to 2020 and tended to stabilize during 2021-2023.Redun-dancy analysis(RDA)revealed that transparency,total nitrogen,and dissolved oxygen were the dominant environ-mental factors affecting fish community structure,followed by water temperature,ammonium nitrogen,and dis-solved total phosphorus.关键词
