Abstract
The Nile tilapia, Oreochromis niloticus, is the queen of the fish; not only in Egypt but also in Africa because it is the food of the poor and the rich. The present work aimed to shed light on how to enhance Nile tilapia seed production through the study of some technological innovation and management aspects in Egypt by introduced  Automated Monitoring and Control System (AMCS) to control water quality in El-Serow Hatchery, Dakahlia Governorate, Egypt. The results showed that from technological innovation viewpoint AMCS has led to positive results: rationalization of water and electricity use; increased the number of fertilized eggs by 23.8 %; increased production of tilapia seed by 20.2 % and improve growth and feed conversion ratio of the newly hatched larvae during nursing period by 23.6% and 14.6%, respectively. Under Automated Monitoring and Control water quality System, in order to obtain the much higher quantity and quality of Nile tilapia seeds, it is recommended to use broodstock at moderate stocking densities:  4.5 and 6.0 fish.m-3 with six ratios 3♀:1♂ during the spawning season in hatcheries.
