摘要
在养虾成本中,饵料费用所占的比例最大。而投饵不足势必影响对虾的生长,投饵过量则不但造成浪费,还会败坏水质。因此,寻找合理的投饵量是降低养虾成本的重要关键之一。我们于1977,1978年7—11月份在浙江省温岭县松门对虾养殖场进行了中国对虾(Penaeus orientalis Kishinouye)不同大小时的摄饵量、生长率的观察实验。现将1978年的实验结果报告如下。
The present observations were aimed at finding out the relationship between the biological characters of Chinese shrimp such as the increase rate of the body weight,length and the amount of daily feeding.The results are expressed by the following regression equations:F=0.0363L^(1.6722)……(1)F=0.4045W^(0.5699)……(2)R_(f)=40.448W^(-0.4301)……(3)W=0.01412L^(2.9465)……(4)R_(g)=72.8W^(-0.9687)……(5)R_(e)=14.372—0.396W……(6)Where L=body length,W=body weight,F=amount of daily feeding,R_(f)=rate of daily food requirement(%),R_(g)=growth rate(%),R_(e)=effect rate of food(%).Time for harvesting the shrimp is also discussed.
