Tilapia is a vital protein source for many countries and is cultured in over 120 countries. The global tilapia production has stably increased in the last decade. However, the production performance of the optimized strains in many farms is much lower than what potentially can be achieved. One important factor is the adaptation capability, which means the ability to adapt to the changing environment. Based on investigating the situation of most productive countries for tilapia in southeast Asia, there are two essential environmental characteristics that mainly cause the production variation, namely hypoxia and salinity tolerance. Necessary solutions to decrease the production losses in tilapia require closing the knowledge gap regarding the genetic basis of adaptation to their environments.
The objective of the current project is to unravel the genomic architecture underlying salinity and hypoxia adaptation mechanism and to investigate genomic selection signatures which will benefit further breeding programs.
