摘要:

2018年3—12月,对西充河下游鱼类资源进行了调查,共记录鱼类6目15科40属47种。其中,新记录的鱼类共8种,同历史记录相比,调查得到的西充河下游鱼类种类减少了35.4%,鱼类小型化现象严重,胭脂鱼Myxocyprinus asiaticus和岩原鲤Procypris rabaudi已消失。综合分析认为:电鱼行为猖獗、嘉陵江干流梯级开发及西充河下游河道渠化可能是导致西充河下游鱼类资源减少的原因。

Abstract:

A survey of fish resources in the lower reaches of Xichong River from March to June of 2018 is conducted.In this survey,a total of 47 fish species,40 genera,15 families and 6 orders are recorded, among which are 8 species.Compared with historical records,it is found that fish diversity in the lower reaches of Xichong River has decreased by 35.4%;the miniaturization of fish is also very serious;Myxocyprinus asiaticus and Procypris rabaudi have disappeared for many years.The comprehensive analysis believes that wild electric fishing behavior,cascade development of the main stream of Jialing River and channelization of the lower reaches of Xichong River are the causes that lead to the decrease of fish resources in the lower reaches of Xichong River.
