The recordings in this collection are the annual progress reports of NACA's regional lead centres in Thailand, China and the Philippines.

The Governing Council is NACA's peak policy body, which meets annually to review the organisation's activities and set priorities for the year ahead.

Erwin Pador presents on climate change vulnerability and adaptation in milkfish farming, the Philippines.

For three years NACA worked with a consortium of partners on a project to strengthen the adaptive capacities of small-scale farmers to climate change. The aim of the “Aquaclimate” project, funded by the Norwegian Agency for Development Cooperation (NORAD), was to identify the likely medium-term impacts of climate change on important aquaculture systems and to develop adaptation strategies that will help farmers to cope with the changes.

This report, the 56th in the series, contains information about the aquatic animal health status of fifteen states in the Asia-Pacific region. The foreword discusses a case definition for acute hepatopancreatic necrosis syndrome ("early mortality syndrome") in cultured shrimp in Asia.

This practical manual "Better management practices for seaweed farming" is produced by the Philippines national team under the ASEAN Foundation supported project "Strengthening capacity of small holder ASEAN aquaculture farmers for competitive and sustainable aquaculture" implemented by NACA in five ASEAN countries. The long-term objective of the project was to assist ASEAN small- scale aquaculture farmers improve their livelihoods by being competitive in markets and improving farm management practices to deliver quality and sustainably produced aquaculture products.
