Can you briefly describe your aquaculture career? After I graduated from the Faculty of Agriculture at Kafr El-Sheikh University, I started at Al-Zawiya farm, which is affiliated with the General Authority for Fish Resources Development. When I left it I had the opportunity to learn from professors in the field, such as Ezzat Zahran and Ismail Radwan, on mono-sex tilapia production technology. I established my own tilapia hatchery in the early 1990s.
