Lymphocystis is a common, chronic and benign infection caused by an iridovirus that results in uniquely hypertrophied cells, typically in the skin and fins of only the more advanced orders of fishes.

This disease card provides information on the causative agent, transmission, host range, distribution and diagnosis of abalone withering syndrome. The disease is caused by an intracellular bacterium Candidatus Xenohaliotis californiensis of the family Rickettsiaceae. Information on diagnosistic methods and references are provided.

This disease card provides information on the epizootic of koi and common carp in Indonesia. The pattern of the recent epidemic in koi and common carp in Indonesia is consistent with that of an infectious disease, but there is as yet no definitive aetiological diagnosis. The Regional Aquatic Animal Health Advisory Group of NACA in its first meeting decided to list Koi mass mortality under Unknown diseases of serious nature in the Quarterly Aquatic Animal Disease report.

The Manual of Procedures for the Implementation of the Asia Regional Technical Guidelines on Health Management for the Responsible Movement of Live Aquatic Animals provides background material and detailed technical procedures to assist countries and territories in the Asia Region in implementing the Asia Regional Technical Guidelines on Health Management for the Responsible Movement of Live Aquatic Animals. The Technical Guidelines were initiated due to increased recognition that disease emergence is often linked to live aquatic animal movements.

The Asia Regional Technical Guidelines on Health Management for the Responsible Movement of Live Aquatic Animals and their associated implementation plan, the Beijing Consensus and Implementation Strategy provide expert guidance for national and regional efforts in reducing the risks of disease due to trans-boundary movement of live aquatic animals. The Technical Guidelines were initiated due to increased recognition that disease emergence is often linked to live aquatic animal movements and causes significant socio-economic losses.

The Expert Consultation on Aquaculture Education in the Asia-Pacific was held in, Vietnam, 2000. The consultation was the final activity of APEC project FWG/02/99 “Collaborative Aquaculture Education Program”. This report gives the findings and papers presented to the Expert Consultation, including the follow-up recommendations for establishing an Aquaculture Educational Consortium, in the form of a network, comprising academic and training institutions in the Asia and Oceania regions.

The sixteen papers in this volume were largely based on the data from a survey of more than 5,000 shrimp and close to 6,000 carp farms in sixteen countries and territories in the Asia-Pacific region. They provide an economic and technical efficiency of production analysis for Asian shrimp and carp farming systems. This survey was conducted under the ADB/NACA regional study and workshop on aquaculture sustainability and the environment (RETA 5534).
