摘要: 为考察铜在循环水与静水养殖系统的凡纳滨对虾组织中的积累，本实验在两种养殖系统中分别添加硫酸铜，并使其浓度保持一致，经过92 d的培养，对铜在虾组织中的积累量进行了测定。结果表明，在两种系统中养殖的对虾，其组织中铜浓度依次为：肝胰腺>鳃丝>甲壳>肌肉，肝胰腺中金属硫蛋白（MT）与肝胰腺中铜的积累有相似变化趋势。循环水系统与静水系统中虾肝胰腺和甲壳中铜的积累量有显著差异，而两种系统中虾鳃丝中铜的积累量差异不明显。

After 92 d, the accumulation of copper ion in different tissues and systems were analyzed. The copper accumulation in different tissues both in recirculating aquaculture system (RAS) and static aquaculture system (SAS) had the same accumulation currence: hepatopancreas >lamella> carapace>muscle. The concentration of metallothionein(MT) in hepatopancreas had the same change with the copper accumulation. The accumulation of copper in hepatopancreas and carapace in different aquaculture systems had significant difference, while copper ion in lamella changed insignificantly.
Key words: recirculating aquaculture system(RAS); static aquaculture system(SAS); Litopenaeus vannamei; accumulation of copper； metallothionein (MT)
