The silver dragon fish is also called double-beard bone-tongue fish, is an ancient 'activated stone' fish, and has very important economic value as a famous and precious ornamental fish. At present, the vast majority of the domestic salangid depends on import, and the native mass culture of the salangid is difficult to realize; because the prior breeding technology of the salangid is limited, the artificial mass culture is difficult to realize. The main reason for limiting the breeding technique is the difficulty in sex differentiation of the male and female silver dragon fish.
The salangid has no specific amphoteric characteristic, cannot be distinguished in external morphology, and is not obvious in male and female fish even in the reproductive season. And the silver dragon fish has hard and thick scales, so the scales cannot be penetrated by means of B ultrasonic, CT and the like to judge the sex. At present, the gonad can be identified only by dissecting and observing, and a simple and accurate method which can be identified without dissecting cannot be realized. The artificial propagation of the fish is greatly disturbed because no means for accurately judging the sex is available; because sex is difficult to distinguish, most farms can only adopt a semi-natural method for breeding but cannot adopt a high-efficiency controllable artificial breeding mode, such as temporary breeding of male and female fishes in ponds, injection of an aphrodisiac and an oxytocin and the like, so that the breeding efficiency and success rate are greatly limited. In order to break the situation that the silver dragon fish in China all depends on import, the artificial propagation of the silver dragon fish becomes a problem which needs to be solved urgently.
