Tilapia culture has sharply expanded throughout the world during the past two decades. Production systems of tilapia have also witnessed a rapid industrialization during this period. As a result, the global production of farmed tilapia has increased from 383,654 metric tons (mt) in 1990 representing 4.5% of total farmed fish production to 3,497,391 mt in 2010, representing 8.9% of total farmed fish production, with an average annual growth of 13.5% (FAO, 2012). This trend has created a gap between seed supply and farmer's demand. Therefore, the major challenge facing tilapia culture industry is the production of sufficient amounts of quality seed.
