1996年5月,浙江省丽水地区松阳县鱼苗试验场,在草、鲢(?)鱼人工繁殖鱼苗过程中出现亲鱼产卵、受精、孵化率低下异常,卵膜自行破裂,集不超卵。宁波市(?)素制剂厂的科技人员在该场共试验催产鱼18批,计200余组,取得令人满意的效果。在人工繁殖中注射催产助剂的试验组,草、鲢、鳙亲鱼的效应时间在水温21～26℃的范围内缩短2小时,产卵量明显提高,亲鱼产卵有3个高峰,产卵量 May 1996, Songyang County, Zhejiang Province, fry seedling test site, the grass, silver carp ()) fish artificial reproduction of fish fry during the emergence of broodstock spawning, fertilization, abnormal low hatching rate, the egg membrane rupture, . Ningbo (?) Su-preparation plant scientists in this field a total of 18 batches of oxytocin test, more than 200 groups, and achieved satisfactory results. In artificial breeding group, the effect of spraying oxytocin on experimental group, grass, silver carp and brood fish was shortened by 2 hours in the range of 21 ~ 26 ℃, and the spawning amount was significantly increased. There were 3 peaks in brood stocking and spawning the amount
