. There is an increasing potential for artificial incubation of tilapia eggs. Hatchability observed in artificial systems is less than 62%. Four chemicals generally used as disinfectants for the fish eggs were tested in a controlled experiment together with ultraviolet irradiation of the water. A range of dose levels was tested for each chemical and is compared and assessed in terms of improved hatching rates. Effective disinfection improved the hatchability of eggs above 90%.
