Abstract

Abstract: The ecological environment of the river is monitoredthrough investigation of the ecological types and biodiversity of fish in Lijiang river.The results show that thebiodiversity of fish in Lijiang river was higher,but with more genu of single species,sensitive species reduced greatly,the submucosa and benthic fish reducedsignificantly,the proportion of omnivorous fish increased,CPUE reduced,economicfish was of miniatunization and younger age.The ecological envirment of water isunder great pressure.

Key words: Lijang river, ecological types of fish, biodiversity of fish
