Genetic breakthrough enhances shrimp disease resistance

A recent study published in the Journal of Aquaculture highlights the potential of genomic selection to improve shrimp resistance to co-infection by Enterocytozoon hepatopenaei (EHP) and white faeces syndrome (WFS). Conducted by Benchmark Genetics in Colombia, the research shows moderate heritability for resistance traits, enabling selective breeding for both disease resistance and growth without negative genetic trade-offs. Genomic selection was found to be more accurate than traditional methods, leveraging multiple genes with small effects. Benchmark has applied these findings to its breeding programme, aiming to produce disease-resistant shrimp, reduce antibiotic use, and promote sustainable aquaculture practices, enhancing profitability and environmental sustainability.
