克拉酮鱼用促生长剂于1986年由宁波市激素制品厂试制成功。1986年～1987年,经不同地区的养殖场进行投喂试验,结果表明:该促生长剂能促进草、鲤,鳊等杂食性鱼类的生长,尤其对鱼种增产更为明显,达7～36％;试验组对虾与对照塘对虾相比,平均每尾虾在25天内多增长1厘米,多增重1克。克拉酮的作用机制主要是提高鱼体蛋白酶的活性,增强鱼体对蛋白质消化吸收的功能。因此,在目前蛋白饲料紧缺的情
Ketoketone fish with growth promoters in 1986 by the Ningbo City Hormone Plant trial success. From 1986 to 1987, feeding experiments were conducted on farms in different regions. The results showed that the growth promoters could promote the growth of omnivorous fish such as grass, carp and shrimp, especially for the increase of fish species, reaching 7 ~ 36%. Compared with the control pond shrimp, the average shrimp in the experimental group increased by 1 cm more in 25 days and gained 1 gram more weight. The mechanism of action of cetoketone is mainly to improve the activity of fish protease and enhance the function of fish to digest and absorb protein. Therefore, the current shortage of protein feed situation
