摘 要:为探究鸭绿江的鱼类资源群落组成现状,于2020年11月-2021年10月在鸭绿江丹东段进行鱼类资源调查。结果表明,共获得31种鱼类,隶属于6目12科29属,其中以鲤形目种类最多,共2科17属19种,占总种类数的61.29%;其次为鲈形目,共4科5属5种,占总种类数的16.13%;其他包括鲇形目2科3属3种,鲑形目2科2属2种,鳗鲡目和七鳃鳗目各1科1属1种。从分区和区系组成上看,鸭绿江丹东流域鱼类大多数属于中国平原区系复合体和北方平原区系复合体,其次为晚第三纪早期区系复合体和南方平原区系复合体。因此,中国平原区系复合体、北方平原区系复合体、晚第三纪早期区系复合体和南方平原区系复合体是组成鸭绿江丹东段鱼类区系的基础。对比已有资料,鱼类种类数明显减少,其原因可能是人类活动加剧造成环境的污染和采样存在一定的局限性等。In order to explore the present situation of the composition of fish resources community in Yalu River,a survey of fish resources was conducted in Dandong section of Yalu River from November 2020 to October 2021.The results showed that a total of 31 species of fish were obtained,belonging to 6 orders,12 families and 29 genera,of which Cypriniformes were the most,with 2 families,17 genera and 19 species,accounting for 61.29%of the total species,followed by Perciformes,4 families,5 genera and 5 species,accounting for 16.13%of the total species.Others include 2 families,3 genera and 3 species in the Siluriformes order,2 families,2 genera and 2 species in the Salmoniformes order,1 family,1 genus and 1 species of each in the Anguilliformes order and the Lampetiformes order.From the perspective of zoning and floristic composition,most of the fishes in the Dandong basin of the Yalu River belong to the Chinese plain floristic complex and the Northern plain floristic complex,followed by the early Neogene floristic complex and the Southern plain floristic complex.Therefore,the Chinese plain floristic complex,the northern plain floristic complex,the early Neogene floristic complex and the Southern plain floristic complex are the basis of the fish fauna in the Dandong section of the Yalu River.Compared with the existing data,the number of fish species decreased significantly,which may be due to the environmental pollution caused by human activities and the limitations of sampling.
