摘　　要：2017年10月至2018年9月,对昆明裂腹鱼(Schizothorax grahami)苗种流水培育池水质现状进行了采样研究,利用因子分析法对水温、DO、pH、TN、TP、NH4--N、NO2--N等监测指标进行分析。结果表明,2018年6—9月,养殖水体水温相对其他月份高,水质较差,影响水质的主要指标为氮和磷营养盐;其余监测月份水质相对较好。在养殖过程中,需对养殖水体中NH4--N、NO2--N、TN和TP进行监测和调控,针对性地做好水质管理,以保证苗种培育水质良好,提高成活率,降低养殖风险。The water quality changes of breeding pond of Schizothorax grahami were investigated in this study,the results provide theo⁃retical support for the breeding and proliferation,disease prevention,conservation of wild population of Schizothorax grahami.The present water quality were studied from October 2017 to September 2018.The monitoring indexwere analyzed by factor analysis meth⁃od.The results indicated that the relatively poor water quality was June to September of 2018,TN and TP were the main index of affect⁃ing water quality;and the water quality of the rest months was relatively good.It was important for monitoring the concentrationchanges of ammonium-nitrogen,nitrite-nitrogen,total nitrogen and total phosphorus in aquaculture water,the water quality management should be carried out assure good water quality,enhance survival rate and reduce the risk of aquaculture.
