This extension manual summarises farm level risk factors and practical management practices that can be used to reduce risks of shrimp disease outbreaks and improve farm production. The recommendations are based on a study conducted in Andhra Pradesh, India. The publication is therefore of particular relevance to Andhra Pradesh, but many recommendations are still of use to farmers from other areas. The study was conducted by NACA, MPEDA, the Aquatic Animal Health Research Institute (Thailand), Siam Natural Resources and AusVet Animal Health Services and ACIAR.
