Abstract
Infectious disease is a major constraint for all aquaculture-produced species. The vast majority of farmed fish and shellfish production is based on stocks that have undergone little or no selective breeding. Because disease resistance is universally heritable, there is enormous potential for selecting for improved resistance to key diseases. This article discusses current methods followed for selective breeding in commercially important aquatic animals for disease-resistant species, including species successfully breed and some bottlenecks. Future directions are highlighted, including implementing cost-effective genomic selection for disease resistance trait, to improve genomic prediction in distantly related populations and the potential of genome editing tools for mapping causative variation underlying disease resistance traits.
