The spontaneous and continuous reproduction of tilapia in captivity during the year was first considered an unexpected asset for the development of fish farming in Africa, and then quickly became a serious handicap for the breeding of this fish in ponds, due to the overpopulation it caused. Various techniques have been used to overcome this obstacle. The advantages and disadvantages of tilapia sexuality for the supply of fry to aquaculturists can be questioned. Among the assets is the possibility for artisanal aquaculturists to produce their own fry.

Among the disadvantages is the difficulty of managing the quality of spawners. The small quantities of eggs produced at each laying require work on a large number of spawners, and the asynchrony between laying makes it difficult to produce large quantities of calibrated fry simultaneously. Finally, the control of undesirable breeding in breeding involves the use of populations
