          Dr. Rafael D. Guerrero III: the Father of Tilapia Sex-Reversal

          July 18, 2006, updated: March 8, 2018

          Among the Filipino fisheries scientists tilapias have always been linked with Dr.

          Rafael D. Guerrero III.

          He observed that one of the most prominent problems in tilapia culture is overpopulation. Tilapia matures after two to three months from its fry stage and can produce as much as 5,000 eggs every three months depending on its size.

          When he took his doctorate degree in Auburn University in the early 1970s, he focused his dissertation on the the production of monosex tilapia into male using synthetic androgens.

          When he returned to the Philippines, he continued his experiment on tilapia sex reversal at the Central Luzon State University in Muñoz, Nueva Ecija where he served as the first dean of its college of fisheries.

          Now, the technology he developed has been adopted not only by Filipino fish farmers but by other fish farmers in other parts of the globe.
