Genetic parameters of Gill-associated virus infection and body weight under commercial conditions in black tiger shrimp, Penaeus monodon

Selective breeding to improve performance of growth and increase disease resistance is becoming commonplace within shrimp aquaculture. Whilst estimated breeding values (EBV) for growth can be evaluated easily in on-farm trials, EBVs for disease resistance are usually obtained from controlled laboratory challenges and may not be indicative of natural infection and resistance in a commercial setting. If they are not the same trait, this will...
