摘要
针对白洋淀围栏养蟹测定出河蟹一昼夜中的摄食节律,然后用r和t检验河蟹体重与日摄食量的关系成正相关,测得体重与日摄食量关系式为:D=0.99189+0.03029W根据白祥淀围栏的供饵能力,计算出蟹种放养数量为300～500只/0.0667hm^2。
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.
