摘要: 为充实有关工厂化循环水养殖系统水质研究数据,提供实际生产理论依据,研究了在循环水养殖系统中饲养吉富品系尼罗罗非鱼(Oreochromisniloticus)成鱼(190g)16天期间水质参数的变化情况,对实验数据进行主成分分析。水质参数包括氨氮、碱度、溶氧、pH和温度,记录实验期间投喂量,及时收集并去除排泄物。主成分分析表明与第一主成分F1(贡献率42.62%)主要关联的是pH、碱度和投喂量;与F2(贡献率27.8%)主要关联的是溶氧和温度;与F3(贡献率为19.3%)主要关联的是氨氮。此外,pH与碱度、氨氮与投喂量、溶氧和温度之间存在显著关系。

Abstract: We conducted a 16-day culture experiment for tilapia (Oreochromisniloticus) to study the relationships among water quality parameters in recirculating aquaculture system. Five water quality parameters (including ammonia, alkalinity, dissolved oxygen, pH and temperature) and the amount of daily feeding were analyzed with principal component analysis. Results showed that the first principal component F1 is mainly related to pH, alkalinity and daily feeding; F2 is mainly related to dissolved oxygen and temperature; F3 is mainly related to ammonia. Besides, there is significant relationship between pH and alkalinity, ammonia and daily feeding, dissolved oxygen and temperature.
