春夏之交各种鱼类进入繁殖旺季,合理使用催产剂是人工繁殖成败的关键之一。1.催产剂的种类常用的鱼类催产剂有:鱼类脑垂体(简称 PG)、绒毛膜促性腺激素(简称HCG)、促黄体生成素释放激素类似物(简称 LRH-A)。若在催产剂中添加一些化学物质,构成复合催产剂,则可显著提高催产效果。各种水产动物对不同催产剂的敏感性各不相同,如鲢、鳙鱼对 HCG 的敏感性优于LRH-A,而草鱼对 HCG 的敏感性较差。
At the turn of spring and summer, all kinds of fish enter the breeding season. Proper use of oxytocin is one of the keys to the success or failure of artificial breeding. 1. The types of oxytocin commonly used fish oxytocin are: fish pituitary (PG), chorionic gonadotropin (referred to as HCG), luteinizing hormone releasing hormone analogues (referred to as LRH-A). If you add some chemicals in the oxytocin to form a composite oxytocin, you can significantly improve the effect of oxytocin. Various aquatic animals have different sensitivity to different oxytocin. For example, silver carp and bighead carp are more sensitive to HCG than LRH-A, while grass carp is less sensitive to HCG.
