Summary:The article presents the results of an experimental study on physiological stimulation of tilapia spawning and methods of early sex detection in juvenile fish. It has been determined that among organic dyes, solution of diamond green has shown the best results in determining the sex of juvenile tilapia. It has been found that the pituitary gland of carp is suitable for stimulation of reproductive products maturation in tilapia and causes spawning behavior in fish. Under controlled conditions, this allows obtaining a constant number of larvae of a certain age and size, which is an essential prerequisite for industrial fish breeding technology.
