They have historically been a significant source of fish for artisanal fishermen in Africa, and their use in farming and aquariums is on the rise. The reverse osmosis process is one of the best tools available to ensure that the water we drink is safe for fish. Since tilapia can tolerate high levels of crowding, producers occasionally push the capacity of recirculating systems by adding pure oxygen to the water. How many tilapia live in a gallon of water? Feminization of the YY genotype is a vital step in the development of the YY technology on a large scale, as it makes possible the production of YY males without the need for time-consuming progeny testing. Make a research about YY Tilapia of Freshwater Aquaculture Center. For example, Mexico invests millions of dollars in restocking programs with hormone sex-reversed tilapia (males with double X chromosomes). treatment, it is a more consistent and reliable technique that achieves over 95 percent male offspring, while it is not rare to see male ratios below 90 percent for hormonal treatment. 0000000016 00000 n Discuss the technology and emphasize the basic concepts in Cell and Molecular Biology adapted and applied. 2.

Once water temperatures reach approximately 70F, fingerlings are stocked at approximately 4,000 to 6,000 per acre depending on the length of the growing season and market preference for size at harvest. In 2001, biologist Dr. Graham Mair concluded that YY male technology provides a robust and reliable solution to the serious and widespread problems of early sexual maturation, unwanted reproduction and overpopulation in tilapia culture. This species is also resistant to a wide range of salinity levels. . Illustrations from Egyptian tombs suggest that Nile tilapia were cul-tured more than 3,000 years ago. The Philippines is now the fourth biggest producer of the fish in the world. Feminization (XY females) can be achieved through gynogenesis by irradiation and hormonal sex reversal or thermal treatment. Although the development process is time-consuming and labor-intensive, once developed, the production of monosex males can be maintained through occasional feminization of YY genotypes. 4 p. Anon.
