This publication is the major output of a regional programme jointly implemented by FAO and NACA in 2015 to document and disseminate successful practices that contribute to the sustainable intensification of aquaculture in the Asia-Pacific region. Twelve practices are described that contribute to at least one of the following: Improved production and resource use efficiency (land, water, feed, energy); improved environmental benefits; strengthened economic viability and farmers' resilience; and improved social acceptance and equity.

The workshop was held in Bali, Indonesia from 6 to 8 November 2013. The programme included reports on current aquatic animal disease situations in selected countries and presentations on the national aquatic animal health programmes of China, Japan and Korea. In addition, case studies on the molluscan diseases, shrimp diseases and finfish diseases were presented to facilitate the subsequent discussion on emergency response of those diseases in the national and regional level.

Small aquaculture farm holders are experiencing some drastic changes, the shift from household consumption focused subsistent production to market oriented commercial production and external environment changes such as tightening governance on environment impacts control and resource allocation and increasingly stringent standard for food safety and quality. To adapt to the changes, the small-scale farmers need to intensify, diversify and commercialise production, which requires better management.

Practices and people can be considered as two key ingredients to responsible aquaculture. Practices that are in conformity with national and international standards and requirements, ensure sustainability of the sector, ensure environment protection and integrity, enable social equity and respect ethical values and standards, consider human food safety concerns seriously and people who; are well informed, willing to change and ready to embrace practices for public good.

Artisanal shrimp aquaculture is in a disease-induced crisis of lost production, into which are falling farms, gene pools adapted to farms, and small-hold farming as a way of life. Rising levels of inbreeding and an exceptionally strong, positive relationship between inbreeding and disease which is described here. The root cause is social: a nexus of human behavior in which breeders protect their intellectual property by generating inbreeding and farmers suffer the consequences.
