Q: how to solve the problem of breeding rice field eel in artificial culture?

Monopterus albus A: At present, the breeding of Monopterus albus, the main source of seedlings are captured in nature, artificial incubation and cultivation of two ways. The eel species cultured by artificial incubation have regular specifications, are not easy to be injured and fish diseases, and have high survival rate. However, artificial propagation of eel seedlings is difficult. Because the eel has a unique phenomenon of sexual reversal in physiology, that is, the eel is female from the first sexual maturity. Female eel after laying eggs gradually transformed into male, after life will not change. This brings great difficulty to artificial propagation of eel seedlings. The so-called artificial incubation culture means that during the breeding period of eel, foam groups (incubation nests of eel) in natural waters are artificially fished out for artificial incubation and cultivation.
