Culturing saline tilapia has become a new trend in the aquaculture due to the scarcity of freshwater resources. In this study, the genetic basis controlling for salt tolerance were investigated by using a ddRAD-seq-based GWAS in 288 individuals with extreme salt tolerant traits from half-sib families of red tilapia. 12 genome-wide significant SNPs and 6 chromosome-wide significant SNPs associated with acute salt tolerance were identified.
