This report makes no reference to specifically numbered generations of selectively bred GIFT because there is no standard nomenclature for these among breeders and researchers. All GIFT are regarded here as a genetically improved breed of Nile tilapia. The Nile tilapia strains that were bred and disseminated through the TA are called GIFT, as are any tilapia bred subsequently using only GIFT genetic material. Tilapia bred by crossbreeding GIFT and other tilapia are called GIFT-derived.
