Genomic architecture of selection for adaptation to challenging environments in aquaculture by Yu, Xiaofei

“…Although a reasonable genetic gain can be achieved by selective breeding, this genetic response may not be enough to adapt fish species to the effects of climate change. Marker assisted selection focusing on specific genes or alleles that allow fish to cope with these changes would allow more rapid adaptation of fish to these new environments. …”
