Abstract

Abstract: The water quality changes of breeding pond of Schizothorax grahami were investigated in this study,the results provide theoretical 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 method. The results indicated that the relatively poor water quality was June to September of 2018, TN and TP were the main index of affecting 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.

Key words: Schizothorax grahami, water quality, analysis
