选取约0.6 g幼龄草食性海洋经济鱼类—梭鱼作为试验对象,采用摄食率法及迷宫法作为试验方法 ,研究饵料中不同比例的浒苔添加量对梭鱼生长的影响,记录试验数据,使用Excel和SPSS软件处理试验数据,结合统计学检验,比较和评价添加不同浒苔剂量的饲料对梭鱼的诱食效果。结果表明:与对照组相比,试验组梭鱼的增重率明显提高并且降低饵料系数,其中以试验2组和3组的效果最为显著,增重率分别提高了57.09%和89.27%,饵料系数降低了35.23%和37.82%。
The selection of about 0.6 g juvenile herbivorous marine economy fish - barracuda as test subjects, the feeding rate method and the maze method as a test method to study the bait in different proportions of Enteromorpha addition of barracuda growth, record test data , Using Excel and SPSS software to deal with the experimental data, combined with statistical tests to compare and evaluate the effect of adding different doses of Enteromorpha bait to the mullet. The results showed that compared with the control group, the weight gain rate of the experimental group was significantly increased and the feed conversion coefficient was decreased. The effects of the two groups and the three groups were the most significant, the weight gain rate increased by 57.09% and 89.27% respectively, Coefficients decreased by 35.23% and 37.82% respectively.
