摘  要：
为了研究不同饵料对月鳢幼鱼生长的影响,2016年7月至2016年11月,采用人工配合饲料、红线虫、蚯蚓、玉米面对月鳢幼鱼进行120d的生长试验。通过对增重率和成活率变化,探讨4种不同饵料对月鳢幼鱼生长的影响。结果表明:不同饵料可影响月鳢幼鱼生长,投喂人工配合饲的试验组月鳢幼苗长势最好,增重率为1024.00%;其次依序为蚯蚓、红线虫。投喂玉米面的试验组最低,增重率为-6.00%。除投喂玉米面的月鳢幼苗成活率为15.28%,其他组均为100%。对采用人工配合饲料饲养的幼鱼的体重与日龄进行回归分析,其生长模型是:H=0.518D~(0.5593),全长与日龄的相关关系:L=0.519D~(0.5588),体重与全长的相关式:H=0.019L2.7856。

摘  要：
In order to study effects of different diets on the growth and development of larvae of Channa asiatica,atthe water temperature of 23~28℃,a 120 d growth experiment which studied the influence of 4 kinds of food(artifi-cial feed,red worms,earthworm,corn meal)on the growth of Channa asiatica was performed based on the changeof their survival rate and the rate of grain in body weight from July to November in 2016.The results showed thegrowth of larvae of Channa asiatica feed on artificial feed was the fastest which was(1024.00±15.78),followed bylarvae of Channa asiatica,red worms and earthworm and the difference among groups feed on different food,and thegrowth of larvae of Channa asiatica feed on artificial feed was the slowest which was-6.00%.The survival rate of lar-vae of Channa asiatica feed on corn meal was 15.28%,the other groups of it was 100%.Regression analysis was car-ried out on the artificial feed of larvae of Channa asiatica. Relationship between body weight and age,the growthmodel is H = 0.5182 D~(0.5593),the relationship of the total length and age is L = 0.519 D~(0.5588),the relationship of bodyweight and body length is H = 0.0193 L~(2.7856).
