埋植17α-甲基睾酮诱导点带石斑鱼性转化技术
Technique of implanting 17α-methyltestosterone to induce the sex reversal of Epinephelus malabaricus
摘要
Abstract
This paper discussed the method of implanting 7a-methyltestosterone to induce the sex reversal of Epinephelus malabaricus, which included chemical treatment, dosage and operating on the fish. After twice implanting of exogenous hormone, the mature females of 3 yearn old were transformed into functional males. Sperm could be squeezed from 5896 of the fish on 139 days after operating, and from 100% on 301days. When the functional males were used for artificial breeding, the parent fish spawned in a natural way, and 71.03 million larvae were hatched in the two years of 1999～2000. The larvae were used for rearing of fish fry, from which normally growing young fish was get. It is believed that the method of implanting exogenous bormone to induce the sex reversal of E. malabaricus is easy and stable, which can satisfy the requirement of artificial breeding in factories.
