Genetic Variation For Resistance To WSS, AHPND In Pacific White Shrimp

: 5784

Summary: Selection for disease resistance has been used in breeding farm animals and can be a viable option to deal with white spot syndrome and acute hepatopancreatic necrosis disease in commercial shrimp culture. The approach is worthwhile when there are no other cost-effective control measures, and there are genetic differences for resistance to pathogens. In trials, heritability for AHPND resistance was low, while that for WSS was moderate. This indicated advancing genetic resistance is feasible, although progress with AHPND [...]
