Abstract:
The Ecdysterone was added into the diets of 28% protein level for Procambarus clarkii to investigate its effects on the growth and molt of Procambarus clarkii． The results showed: the Ecdysterone group was increased by 15. 46%， 12. 08%， 11. 63%， 50% in the net increase of the body weight，the specific body weight growth rate，the survival rate， the molt frequency; the feed coefficient decreased by 29. 51%， 11%; the net increase of the body length and the specific body length growth rate increased by 38. 71%， 51. 61%( P ＜ 0. 05) ，comparing with the control group． This study indicated that proper addition of Ecdysterone into the feed was appropriate for the culture of Procambarus clarkii．
