  • GMT - Red Tilapia

    GMT - Red Tilapia

    YY males have been developed in a pure red strain of O. niloticus. This is a popular strain of red tilapia already being grown in many countries. The Red GMT will be available in the second half of  2002.

    GMT - Pearl

    A new colour variety has arisen in one of the stocks of pure O. niloticus held in the U.S.A. known as 'Pearl'. This is a whitish coloured fish with a very attractive appearance. Unlike red tilapia the Pearl has a clean uniform colour with no black markings. We still need to study the inheritance of this colour mutation so true breeding Pearl GMT are unlikely to be available before 2003.

These O. mossambicus have considerably more genetic variance than those used in aquaculture today and are anticipated to have much superior growth rates to current aquaculture stocks of this species. O. mossambicus GMT should be available by late 2002 and will be of great interest to farmers in regions in which...

The most effective solution to this problem is to produce and grow only male fish. Fishgen have addressed this problem in an innovative way through the application of...
