This report, the 66th in the series, contains information about the aquatic animal health status of fourteen states in the Asia-Pacific region. The foreword discusses key activities of the NACA Regional Aquatic Animal Health Programme.

The main objective of this symposium is to provide a venue for information sharing on extension of small-scale aquaculture, specifically targeted to those individuals and relevant organizations involved in various aquaculture development projects. The symposium will also assess and present the effectiveness of “farmer-to-farmer extension” approach in the implementation of relevant aquaculture development projects in the region. The symposium was organised for stakeholders in JICA-assisted projects in SE Asia and Africa.

We describe a new method for detecting isolates of Vibrio parahaemolyticus that cause acute hepatopancreatic necrosis disease (AHPND). This method is based on the gene sequence of a protein discovered in a sub-fraction of cell-free culture broth from isolates of V. parhaemolyticus that cause AHPND, but not from V. parahaemolyticus or other bacteria that do not cause AHPND. This cell-free preparation caused the typical signs of acute AHPND when administered to shrimp by reverse gavage.
