The daily feeding regulation of Crab was determined based on fenced watercrab culture in Baiyangdian lake. Then t and r test were used to testified the postive correlation between body weight of crab and its own daily ration. The formula was as follow: D=0. 99189 + 0. 03529W According to the productivity of fenced water in Baiyangdian lake, the'proper stocking density was 300-500/0. 0667hm2.
