四种饲料添加剂对中国龙虾生长的影响

Effects of four additives in artificial diet to growth of spiny lobster (Panulirus stimpsoni)

本文以人工配合饲料为对照组 ,4种添加剂为实验组 ,对中国龙虾进行 50d的生长试验 ,结果表明 :复合脱壳素 (实验组 1 # )效果最佳 ,其次分别是脱壳素 (实验组2 # )、甲壳粉 (实验组 3 # )、喹乙醇 (实验组 4# )和对照组 ,其增重率分别为 :1 7.0 8%、8.41 %、7.62 %、5.45%和 4.2 1 %;蜕壳率分别为 58.3 3 %、50 .3 3 %、3 3 .3 3 %、3 3 .3 3 %和 3 3 .3 3 %;蜕壳后增重率为 2 9.2 9%、1 6.90 %、2 2 .85%、1 6.43 %和1 2 .68%;饲料系数分别为 7.57、7.1 1、7.92、1 1 .0 0和 1 4.2 1 ;对照组和实验组 4# 存活率为 91 .67%,其余均为 1 0 0 %.整个试验过程龙虾生长良好 .

An experiment on feeding of the spiny lobster (P. stimpsoni) with artificial diet by four additives is summed for 50 days in this paper, which are the complex molt hormone, molt hormone, shell powder and olaquindox respectively. The results show that adding various diets will all accelerate the molt and growth of the spiny lobster. In the experiment group 1 # (adding the complex molt hormone), the affection is especially remarkable. In the experiment groups and the control group, the body weight growth rates of the spiny lobster are 17.08%, 8.41%, 7.62% , 5.45% and 4.21%; the intermolt periods are 58.33%, 50.33%, 33.33%, 33.33% and 33.33%; the molt body weight increments are 29.29%, 16.90%, 22.85%, 16.43% and 12.68%; the food coefficients was 7.57, 7.11, 7.92 11.00 and 14.21; the survival rates are 100%, 100%, 100%, 91.67% and 91.67%, respectively. The spiny lobster grows well during the test's period.
