中国对虾体内几种重要无机元素的含量
李荷芳1, 刘发义1
中国科学院海洋研究所
摘要:
用原子吸收分光光度技术和比色法测定了不同体长的对虾,包括亲虾及不同组织中的K、Na、Ca、Mg、Mn、Cu、Zn、Fe和P的含量。除Mn以外,上述元素在对虾整体的含量随着体长的增加呈规律性的变化。值得注意的是,微量元素cu在对虾中的含量相当高,特别是在内脏中的含量非常高,因此存研制人工配合饵料时应注意是否会出现缺铜的问题。

DETERMINATION OF IMPORTANT INORGANIC ELEMENTS IN PRAWN, PANAEUS ORIENTALIS
Abstract:
Contents of K ,Na ,Ca ,Mg,Mn, Cu, Zn and Fe in the whole bodies and the museles of different length prawn, Panaeus orientalis, were determined with atomic absorption spectrophotometers, and P was done with colorimetric analysis. The contents of the elements in the viscera of parent prawn was also determined. In general, the contents of P and K in the whole bodies are the highest, and among the trace elements, Cu, Zn, Fe and Mn, the content of Fe is the highest, and Cu the next. It is, however, noticed that the content of Cu is very high, even though that in seawater and diets is very low. The contents of ail 9 elements in both whole bodies and muscles varied in different body size of the prawn.
