The GIFT line of Nile tilapia is being distributed throughout Asia, therefore, documentation
of its performance for important traits such as cold tolerance is needed as a single trait
does not measure a genotypes overall aquaculture value. Also, cold tolerance of Nile tilapia
developed in a tropical climate then transferred to a temperate climate where Nile tilapia
already exists needs evaluation. Cold tolerance has not been previously studied for Nile
tilapia in China.
