摘要
为摸清目前坡岗自然保护区鱼类区系组成,于2017年和2018年2次对保护区鱼类进行了野外调查,共整理出鱼类73种(亚种),隶属于6目17科54属,其中纯淡水鱼类72种(亚种),降河洄游1种,原著鱼类62种,外来11种(亚种)。与之前调查相比,本次调查新增鱼类25种(亚种)。综合分析表明,保护区鱼类物种数较高,区系成分复杂,起源古老,生态类群多样,具有较高的经济价值和科研保护价值,但人为干扰影响较大,加强其鱼类资源的保护,对维护生物多样性和生态平衡意义重大。
In order to uncover the fish resources of Pogang Nature Reservein Xingyi,Guizhou Province,two field investigations were carried out in 2017 and 2018,respectively.A total of 73 species and sub-species of fish were discovered.These fish belong to six orders,17 families and 54 genera. They were 72 pure freshwater species and one catadromous species; 62 indigenous species and 11 invasive species and subspecies.Compared with previous surveys,this survey added 25 more species and subspecies of fish. The comprehensive analysis showed that the number of fish species in the reserve is high,the faunal composition is complex,the origin is ancient and the ecotypesare diverse. The reserve has high economic value and scientific research protection value. Human disturbance has serious influence on the reserve. Thus strengthening the protection of fish resources in the reserve is of great significance to the maintenance of biological diversity and ecological balance.
