Abstract: To study the effects of glucose and vitamin C (VC) on early development of Puan silve crucian carp (Carassius auratus gibelio), we studied the membrane time, hatching ratio, survival rate and growth characteristics of C.auratus gibelio socked in glucose and VC solutions by static aqueous solution immersion. The results show that when the concentration of glucose was below 15 gL-1 and concentration of VC was below 30 mgL-1, the membrane time of larvae was decreasing and the hatching ratio, survival rate, weight and full-length were increasing with the increase of concentrationsglucose and VC. Concentration of glucose solution higher than 15 gL-1 and concentration of VC solution higher than 30 mgL-1 had inhibitory effect on early development of C.auratus gibelio. The research indicates that appropriate concentrations of glucose and VC can promote early development of C.auratus gibelio.
