| 摘 要： | 为了解云南高原湖泊鱼类资源及多样性现状,于2007-2008年对云南高原11个大型湖泊进行了2次调查.共鉴定鱼类39种,隶属于7目13科33属,鲤形目鱼类最多,占65.0%.其中共调查到土著鱼类14种,外来鱼类25种.在种数上,外来鱼类已经成为各湖泊的主体.在鱼类区系上,由高原鱼类区系向长江中下游鱼类区系演变.主要经济鱼类年龄结构以0+和1+鱼为主.分析表明,土著鱼类多样性与海拔和湖泊面积密切相关.土著鱼类物种数在中等海拔(1700-1800m)处最高,并与湖泊面积呈显著正相关.最后根据调查结果,提出了一些保护建议.

| Abstract: | To study current status of fishery resources and fish diversity in Yunnan Plateau lakes,a survey was carried out in 11 lakes during 2007-2008.Total 39 fish species belonging to 7 orders,13 families and 33 genera were recorded.Cypriniformes were the richest,accounting for 65.0% of total fish species.There were 14 native fishes and 25 exotic fishes being recorded during the survey.In terms of species richness,exotic fishes have dominated in each lake.Fish fauna is characteristic of a shifting from the Plateau... |
