Genomic selection applications can improve the environmental performance of aquatics: A case study on the heat tolerance of abalone
Abstract Aquaculture is one of the world's fastest‐growing and most traded food industries, but it is under the threat of climate‐related risks represented by global warming, marine heatwave (MHW) events, ocean acidification, and deoxygenation. For the sustainable development of aquaculture, se...

In this study, we estimated the heritability of heat tolerance trait of Pacific abalone Haliotis discus hannai , performed genome‐wide association studies (GWAS) analysis for heat tolerance to detect single nucleotide polymorphisms (SNPs) and candidate genes, and assessed the potential of genomic selection (GS) in the breeding of abalone industry.
