Abstract
为了解决水产养殖生产中鱼类动物蛋白饲料严重不足的难题，探究其对鲤鱼生长率、鱼产品品质的影响，采用不同梯度添饲蚯蚓养鲤的方法，按鲤鱼体重的0.5%、1.0%、1.5%、2.0%添饲蚯蚓，比较不同添饲蚯蚓量对鲤鱼养殖效果的影响。结果表明：1) 生长速度：试验组增重倍数10.59倍，比对照提高7.29%；2) 饵料系数：试验组饵料系数为1.68，比对照低0.26；3) 脂肪酸组成及含量：试验组的脂肪酸C14H28O2、C16H30O2和C16H32O2含量比对照明显增加。结论：添饲蚯蚓可显著促进鱼类生长，降低饵料系数，提高鱼产品风味口感。 In order to solve the problem of the severe shortage of the feeding stuff of fish protein in aquaculture production and explore its effects on the growth rate and the product quality of carp, we adopted the method of adding a certain amount of earthworms in the feeding stuff according to the weight of the fish: 0.5%, 1.0%, 1.5%, 2.0%. Then, we compared their effects on carp breeding respectively. The study found that the weight ratio of the experimental group is 10.59 times, which is 7.29% higher than that of control group. The FCR in experimental group is 1.68, which is lower than that in control group by 0.26. Also, the study found that fatty acids C14H28O2, C16H30O2 and C16H32O2 content in experimental group increased significantly compared with the control group. Conclusion: Adding earthworms to feed the carps can not only significantly promote the growth of fish, but also reduce the FCR and improve flavor of the products.
