The shrimp farming case study was conducted in Cà Mau and Bạc Liêu provinces, Mekong Delta, Southern Vietnam by: (1) organized stakeholder workshops to map farmer's perceptions, adaptation measures and agencies involved; and (2) questionnaire survey to assess vulnerability of the production system to climatic changes and extreme climatic events. Farmer perceptions of climate change and possible adaptation measures were identified. Policy frameworks including the policy options were recommended and an action plan proposed.

This brief summarises the results from the interdisciplinary study conducted within the Aquaclimate project in Ca Mau and Bac Lieu provinces of the lower Mekong Delta looking at the impacts of climate change on small scale improved polyculture systems. The brief provides guidelines for policy development to address the climate change impacts on small scale improved polyculture farming systems in Vietnam and how adaptation measures should be implemented in the region.

The brief provides guidelines for policy development to address the climate change impacts on small scale improved polyculture farming systems in Vietnam and how adaptation measures should be implemented in the region. The guidelines are based on recommendations from stakeholders including farmers.

Outcomes of emergency consultation on shrimp early mortality syndrome / AHPNS. Workshop on Aquaculture Planning and Management Tools. Workshop on Proficiency Testing Programme for Aquatic Animal Disease Diagnostic Laboratories in Asia-Pacific. AFSPAN Project gets underway.

In the absence of identified biotic or abiotic cause(s) of the syndrome, this disease card provides information on signs that can be used for presumptive (pond level) and confirmative (animal level) diagnosis of acute hepatopancreatic necrosis syndrome of shrimp. The syndrome involves mass mortalities of up to 100% during the first 20-30 days after stocking. Affected shrimp consistently show an abnormal hepatopancreas, which may be shrunken, swollen or discoloured; loose shells, corkscrew swimming, pale colouration and slow growth.
