Abstract: Objective: The contents of inorganic ions, free amino acids in muscle and ointment of Chinese mitten crab were systematically studied in this paper.  Methods: The test is divided into two groups, one experimental groups, one control group. Control group treated with normal saline, the experimental group were administered with 0.5% Zhiqi fungal substance,.Then, The contents of inorganic ions, free amino acids in muscle and ointment of Chinese mitten crab were carried out. Results: The results showed that the experimental group increased the contents of inorganic ions, free amino acids in muscle and ointment. [Conclusion ]The present observation confirms that right amount of the Zhiqi fungal substance can Promote crab quality in Chinese mitten crab.
