The paper discusses the existence forms of Cd and its toxicity, et al. And we also introduce the steps to set up the Hygienic Standard of chemical detriments control in China.We suggest to do something as follow: First, to begin a study on the toxicity, accumulation and organic active of Cd absorbed by fish that contained in feedstuff. Then, to search wildly on the common large mount of feedstuff for aquatic animals to find out their Cd content level. Finally on the basis, aiming to establish reasonable standard for the permit rang of Cd control in fishery feedstuff.
