长江流域外来鱼类现状与生态风险评估
Status and ecological risk assessment of alien fish in the Yangtze River basin
摘要
Abstract
In order to assess the current status and ecological risks of alien fishes in the Yangtze River basin,we compiled a list of alien fish species in the Yangtze River basin based on various sources,and the Aquatic Species Invasiveness Screening Kit(AS-ISK)was used to evaluate the risk of alien fishes.The results showed that①there are 38 species(belonging to 29 genera,15 families and 8 orders)of alien fishes in the natural waters of the Yangtze River basin,including Cypriniformes(17 species),Siluriformes(7 species),Perciformes(5 species),Acipenseriformes(4 species),Characiformes(1 species),Cyprinodontiformes(1 species),Osmeriformes(1 species),Lepisosteiformes(1 species),the largest number of alien fish from Asia(17 species),and most of the introduction purposes are aquaculture(20 species);②alien fishes have been widely distributed in various rivers and lakes in the Yangtze River basin,and the mainstream of the Three Gorges Reservoir has the largest number of species(22 species);③based on the basic risk assessment of the AS-ISK,19 species of fish were classified as high risk,6 species as medium risk,and 13 species as low risk.The five species with the highest risk scores are Gambusia affinis,Hypostomus ple-costomus,Oreochromis niloticus,Micropterus salmoides and Oreochromis mossambicus.The research shows that the alien fishes in the Yangtze River basin present a large number of species and complex distribution pattern.Currently,no serious neg-ative impact of alien fishes on the ecological security of the Yangtze River basin has been found,but the risk level assessment results indicate that alien fishes have extremely high potential hazards.The results of this study can provide important data and theoretical reference for the prevention and control and management of alien fish in China.关键词
