亮斑扁角水虻幼虫部分替代人工饲料对黑斑蛙生长影响研究

A Study on the Growth of Pelophylax nigromaculatus Using Hermetia illucens L. Larvae Partial Replacement of Artificial Feed

采用武汉品系亮斑扁角水虻老熟幼虫部分替代饲养黑斑蛙的人工饲料,并对黑斑蛙的生长指标和营养指标进行了测定。结果表明,当黑斑蛙人工饲料中添加亮斑扁角水虻幼虫0、25%、50%、75%、100%时,黑斑蛙增重率分别为8.14%、8.52%、32.31%、18.19%、18.99%,特定生长率分别为0.22%/d、0.23%/d、0.79%/d、0.47%/d、0.49%/d。当替代量在50%时,黑斑蛙肥满度、肌肉粗脂肪、肌肉粗蛋白的含量达到最高值,收获黑斑蛙的增重率和饲料系数与其余处理组相比也达到了最优值。因此,使用亮斑扁角水虻幼虫部分替代人工饲料养殖黑斑蛙有较好效果,替代量为50%时最佳,为水虻及其衍生产品在蛙类养殖上的应用奠定了实践基础。

This research used Wuhan strain Hermetia illucens L. larvae as replacement of artificial frog feed, and then mensurated growth index and nutritional index of the Pelophyh nigromulotus. The results show that when the replacement ratio are 0, 25%, 50%, 75%, and 100%, respectively, the weight gain rate of P. nigromaculatus are 8.14%, 8.52%, 32.31%, 18.19%, and 18.99%, respectively, the specific growth rate of P. nigromaculatus are 0.22%/（t, 0.23%/d, 0.79%/d, 0.47%/d, and 0.49%/d, respectively. When the replacement ratio is 50%, the fat content, muscle fat and protein content of P. nigromaculatus reach the highest value. The weight gain and feed coefficient of the P. nigromulatu also reach the optimal value compare with the other treatments. Therefore, the use ofHermetia illucens L. larvae as artificial feed to breed P. nigromaculatus has a good effect, and the best replacement ratio is 50%. Our research has laid the foundation for the practical application of black soldier fly and its derivatives in frog breeding.
