WebNile tilapia ( Oreochromis niloticus) is the most cultured freshwater species among the farmed tilapia and contributes about 71% of the world total tilapia production. Transgenesis is one of the most promising technologies for generating relatively rapid genetic improvements. Important Considerations Land, Water And Soil. Many such populations are inferior to wild-caught stocks, even though the latter are often not particularly well adapted to the captive environment. The marine fisheries production contribution to total fish production in 201617 was 15.42% with a growth rate of 1.75% ( Table 1 ). Economic Importance. With the failure of hybridization to effectively solve the problem of early sexual maturation, unwanted reproduction, and overpopulation in tilapia culture, alternative technologies were sought. Illustrations from Egyptian tombs suggest that Nile tilapia were cultured more than 3,000 years ago. Attempts to commercialize monosex hybrids, usually with the O. niloticus O. aureuscross or using male O. urolepis hornorum with females from O. niloticus or O. mossambicus, have met with varied success. Phosphorus 4. O. aureus, or more often its hybrid with O. niloticus, is grown in some regions, due in part to its cold tolerance.
