Overview
This study was designed to improve our understanding of the main causal pathways for white spot disease (WSD), the most serious cause of production loss in these systems. The longitudinal observational study focused on recording the occurrence of different genotypes of the causal infectious agent, white spot syndrome virus (WSSV), in selected components of the system across time, and looking for relationships with pond outcomes, particularly WSD occurrence.
This project aimed to:
- Determine the stability of WSD outbreak-associated WSSV genotypes when passaged through WSSV-free Litopenaeus vannamei, WSSV PCR test-negative P. monodon and selected other WSSV PCR test-negative, non-penaeid hosts.
- Identify the likely determinants for WSD outbreaks at a suitable, broadly representative locality in South Sulawesi.
