| 摘要: |
| 针对目前对虾配合饲料中镉含量超标的现象以及现行标准中对虾配合饲料的镉限量要求严格而又缺乏相应研究数据支持的现状，以南美白对虾(Penaeus vannamei)作为研究对象，通过在饲料中添加氯化镉和乌贼内脏粉作为相应的无机镉、有机镉来源进行养殖对比实验，对对虾体内的镉含量进行分析，结果表明,通过饲料进入对虾体内的镉主要蓄积在内脏中，同等浓度的有机镉和无机镉饲料，在对虾体内前者的残留量要小于后者。同时通过养殖试验数据推算得到目前我国对虾配合饲料中镉应以总镉形式限制≤3.0 mg/kg，这一限量要求是适合于当前水产养殖生产的，也能够保障对虾的食用安全性。 |

| The prelimimary research on limits to cadmium in prawn formula feed |

| Abstract: |
| The current situation is that there is a high concentration of cadmium in prawn formula feed but the standard of cadmium in feed is too strict and the relevant research results are not proposed. In this study, white-legged shrimps were used as an experiment object. Cadmium chloride and Cuttlefish viscus powder were added to the feed as the inorganic cadmium and organic cadmium respectively. After analyzing the cadmium concentration in the prawns, the results suggested that the cadmium from the feed mostly accumulates in prawn's viscus. With the same concentration of organic cadmium feed and inorganic cadmium feed, the cadmium accumulated from the former is less than from the latter. Meanwhile, according to the data from our research, the cadmium critical limit in prawn formula feed in China is calculated to be not more than 3.0 mg/kg, which is considered to be proper for the domestic fishery. |
