Disease Risk Factors For Shrimp Production In Brazil

摘要

For two years of data, the effects of management, season, stocking density and salinity on the incidence of disease in northeastern Brazil's shrimp farms were found highly significant. Growout facilities with management problems had 8.6% more IMN outbreaks than well-managed farms. The hot summer season had fewer disease outbreaks than winter. Low salinity reduced IMN incidences. Stocking density also affected IMN and NHP outbreaks. Nurseries presented higher risk than direct stocking.
