Its main focus is genetic enhancement in tilapia, promoting these technologies through consultancy services and sales of improved fish. This has placed a demand on the fish breeding industry to produce mono-sex tilapia, i. Thus, it was successfully demonstrated that GIFT can make a notable contribution to improving the food and nutrition security and augmenting the household income of farmers.
Most work has focused on using hybrids of the Mozambique tilapia Oreochromis mossambicuswhich is mono sex tilapia breeding in Cape Coral to be saline-tolerant but has inferior growth rates. This will for instance occur when Blue tilapia Oreochromis aurea or Zanzibar tilapia Oreochromis hornorum males mate with Nile tilapia Oreochromis nilotica or Mozambique tilapia Oreochromis mossambicus females.

Home Publications. Dani, A. The strategy aims to boost fish supply from aquaculture to 12, tons by and contribute to reducing widespread malnutrition by increasing average annual per capita consumption of fish from 6. The environmentally friendly mono sex tilapia breeding in Cape Coral requires no special facilities and also eliminates the expensive, time-consuming, and often variable hormonal sex-reversal techniques.
Author s Pant, J. In some species of fish, transgenics have exhibited physical abnormalities, but tilapia transgenics are normal in appearance. All tilapia exhibit early sexual maturity that leads to uncontrolled reproduction and large numbers of stunted and often unmarketable progeny.
Cuban scientists have also developed transgenic tilapia. Scaling successful GIFT farming technologies in a wider agro-ecological context is crucial for creating lasting impacts on the livelihoods of a large number of resource-poor households across Timor-Leste.
Their nontransgenic siblings could only reach a maximum weight of 0. It is mono sex tilapia breeding in Cape Coral carried out by feeding newly hatched tilapia fry with special hormone treated food for weeks. The effects of the transgene on growth are so marked that in large samples, the distribution of weights of transgenics and non-transgenics did not overlap.
The normal genetic male progeny are termed genetically male tilapia GMT. Author s Pant, J.
On-farm testing and validation of GIFT farming technologies in Timor-Leste, which the guidelines in this document are based on, became possible because of the voluntary participation of all the FFS participants across Ermera, Baucau and Bobonaro. Preliminary results for cold tolerance appear promising.
The environmentally friendly technology requires no special facilities and also eliminates the expensive, time-consuming, and often variable hormonal sex-reversal techniques. All sessions will be recorded and available on-demand for later viewing.
