研究青海钩虾对罗非鱼两品系吉富罗非鱼和彩虹鲷生长的促进作用。实验用青海钩虾与面粉、麸皮和豆饼制成 5组 ( ～ )配合饲料及良种场原用饲料 ( 组 )饲育吉富罗非鱼和彩虹鲷 ,经2 5 d试验结果表明 :( 1)彩虹鲷增重效果以 组饲料最高 ,平均增重为 4 4 .9g,较大于 组的 4 3.1g;( 2 )所有钩虾饲料对彩虹鲷的增色效果都高于良种场的原用饲料 组 ,其中以饲料 组最高 ;( 3)饲料 I组饲育吉富罗非鱼平均增重为 4 4 g,高于 组的 4 0 .1g;( 4 )吉富罗非鱼和彩虹鲷比较则显示出吉富罗非鱼的增重率明显高于彩虹鲷而饵料系数又较低的结果。
To study the effects of Goby shrimp on the growth of two lines of tilapia (Tilapia tilapia) and rainbow seabream (Tilapia tilapia). The results showed that: (1) Five groups (~) of compound feed and the original feed (group) of breeding field were used to breed GIFT tilapia and rainbow seabream with Qinghai hook shrimp, flour, wheat bran and soybean cake. Rainbow snapper weight gain effect with the highest feed group, the average weight gain of 449g, larger than the group of 4 3.1g; (2) all hook shrimp feed rainbow seabream color enhancement effect is higher than the original field of feed , Of which the highest feed group; (3) feed group I fed GIFT tilapia average weight gain of 4 4 g, higher than the group of 40.1 g; (4) GIFT tilapia and rainbow seabream comparison shows that the rich The weight gain rate of tilapia was significantly higher than that of rainbow seabream and the food coefficient was lower.
