摘要
目前泥鳅的人工繁殖已成为泥鳅集约化养殖的重要方法,其中,人工催产又是人工繁殖的核心部分。通过采用不同配比的催产激素对泥鳅进行人工催产,统计催产后自然受精获得的卵粒数,并比较相应的药物成本后认为,催产激素浓度越高,相应的催产效果越好;相同药物成本下,混搭催产所产的卵粒数远高于单一催产所产的卵粒数,50IU/0.2mLHCG+0.25μg/0.2mLLRH-A2+0.2mg/0.2mLDOM混搭的效果最佳。
The artificial propagation of loach has been an important method for loach intensive culture,among them artificial induced spawning is also the core part of artificial propagation.Different ratios of oxytocin was used for the artificial induced spawning of loach,and then the number of ovum obtained from natural fertilization was recorded,and drug cost was compared.Results showed that the higher oxytocin was,the better spawning effect was.Under the same drug cost,the number of ovum produced by mixed induced spawning was higher than that of single induced spawning,among them 50 IU/0.2 mL HCG+0.25 μg/0.2 mL LRH-A2+0.2 mg/0.2 mL DOM had the best effect.
