CENIACUA Develops WSSV-Resistant Shrimp In Colombia

摘要

The 1999 appearance of white spot syndrome virus (WSSV) in white shrimp caused high mortality at shrimp farms in Colombia. To combat the disease, Corporation Centro de Investigation de la Acuacultura de Colombia (CENIACUA) initiated a selective-breeding program to develop WSSV resistance in shrimp. After initially poor survival and slow growth in resistant animals, more recent trials involving segregated and mixed populations of selected and non-selected shrimp, CENIACUA achieved populations much more resistant to WSSV than populations not selected for WSSV.
