Abstract: This paper is to research the effect of Zhiqi Fungal Substance on composition of inosine monophosphate in Eriocheir sinensis. Eriocheir sinensis were allotted into 2 groups randomly. The control group were fed with basal diet, the others were the treated groups fed with basal diet supplemented with 0.5% Zhiqi Fungal Substance for 90 days. Finally, Inosinic acid contents in the muscle and gonads of mitten crabs were determined by HPLC. The results showed Zhiqi Fungal Substance can imporve the  contents of inosine monophosphate in Eriocheir sinensis.It is indicated that dietary Zhiqi Fungal Substance can improve the flavor of cultured shrimp.
