摘要: 为研究封闭循环水养殖条件下水质参数变化对水体和养殖对象肌肉中重金属含量的影响,以初始体重为(57.9±0.87) g的吉富罗非鱼(Oreochromis niloticus)为试验对象,在模拟实际工况的小型循环水系统中养殖60天,通过控制不同水质因子包括碱度、溶解氧和固体总悬浮颗粒物(TSS)水平的高低,观察其最后对水体和鱼体重金属含量的影响。结果显示,碱度对水中Cu、Zn浓度及试验鱼肌肉中Zn含量有显著影响,溶解氧对水中Cu浓度及试验鱼肌肉中Cu、Zn含量有显著影响,而TSS水平高低对水体和鱼肌肉重金属含量均没有显著影响。试验期间,试验鱼可食用部分重金属含量符合国家和行业标准。

Abstract: To investigate the effects of water parameters on the concentrations of heavy metals in water and fish muscle in recirculating aquaculture systems (RAS), using tilapia (Oreochromis niloticus) weighed (57.9±0.87) g as experimental creature, we conducted a 60-day experiment in 8 small RASs simulating the actual work condition with changing several water parameters including alkalinity, dissolved oxygen (DO) and total suspended solid (TSS). The results showed that at the end of the experiment, alkalinity had obvious effect on the content of Cu, Zn in water and content of Zn in muscles; dissolved oxygen had obvious effect on the content of Cu in water and contents of Cu, Zn in muscles; TSS had no significant effect on contents of heavy metals in both water and muscles. However, in such experimental conditions, the contents of heavy metals in the muscle (the edible part of fish) of tilapia were under the limits of the national and industrial standards.
