Monodon slow growth syndrome and Laem-Singh virus retinopathy: Disease card

During 2002, slow growth of farmed Penaeus monodon was reported throughout shrimp growing areas of Thailand and figures indicated that annual production volume was reduced by approximately 36%. The cause of this slow growth was not determined but laboratory trails suggested that a filterable infectious agent was involved. Injected extracts affected P. monodon but not P. vannamei. The slow growth condition was referred to as monodon slow growth syndrome or MSGS. This disease card provides an overview.

Specific pathogen free (SPF) organism information sheet

This information sheet provides an explanation and background information on Specific Pathogen Free organisms. Key points include that SPF animals are designated to be free from specified pathogens, only. The SPF status simply provides an assurance to the buyer that the stock is not infected with the specified pathogens at the time of purchase. The SPF status is lost when animals are removed from biosecure facilities.

White tail disease of Macrobrachium rosenbergii

White tail disease in Macrobrachium rosenbergii is emerging as a serious problem in the region. Two viruses, M. rosenbergii nodavirus (MrNA) and extra small virus (XSV) have been found to be associated. The role of MrNV and XSV is not yet clear. Considering the economic impact and potential for the disease to spread, white tail disease (MrNV and XSV) has been listed under non-OIE listed crustacean diseases relevant to the region and NACA/FAO/OIE Regional QAAD list.

Grouper iridoviral disease: Disease card

Recognising the importance of iridoviral disease, in terms of its potential to spread and cause economic loss, grouper iridoviral disease was included for listing in the quarterly aquatic animal disease (QAAD) list under any other diseases of importance effective for reporting from first quarter of 2003. This disease card is developed to provide information to national authorities and support the regional NACA/FAO/OIE QAAD reporting system.

Asia diagnostic guide to aquatic animal diseases

The Asia Diagnostic Guide to Aquatic Animal Diseases or ‘Asia Diagnostic Guide’ is a comprehensive diagnostic guide in support of the implementation of the Asia Regional Technical Guidelines on Health Management for the Responsible Movement of Live Aquatic Animals. It was developed from technical contributions of members of the Regional Working Group and Technical Support Services and other aquatic animal health scientists in the region and outside who supported the Asia-Pacific Regional Aquatic Animal Health Management Programme.

Abalone viral mortality: Disease card

Recognising the importance of abalone viral mortality, in terms of its potential to spread and cause economic loss, "abalone viral mortality" was included for listing in the regional NACA/FAO/OIE quarterly aquatic animal disease (QAAD) reporting list under "unknown diseases of serious nature" effective first quarter of 2004. This disease card is developed to provide information to national authorities and support the regional QAAD reporting system.

Haemorrhagic disease of grass carp: Disease card

Hemorrhagic disease of grass carp is a serious viral disease affecting grass carp fingerlings. The disease has the potential to spread and cause serious economic loss in countries of the region. This disease card is developed to raise awareness and support surveillance efforts of countries in the region.

Akoya oyster disease: Disease card

Akoya oyster disease is of concern to the region and was included in the Regional NACA/FAO/OIE quarterly aquatic animal disease (QAAD) reporting list, effective first quarter of 2003, to assist in the collection of occurrence data. This disease card will support the surveillance programs of countries in the Asia-Pacific region.

Epizootic ulcerative syndrome: Disease card

Epizootic ulcerative syndrome (EUS) is a seasonal epizootic condition of wild and farmed, fresh and brackishwater fish. Of complex infectious aetiology, it is characterised by the presence of invasive Aphanomyces infection and necrotising ulcerative lesions typically producing a granulomatous response. The disease is now endemic in South-east and south Asia, and has recently extended to West Asia. EUS is indistinguishable from red spot disease of eastern Australia and mycotic granulomatosis of Japan.

Infection with koi herpes virus: Disease card

Koi herpes virus (KHV) outbreaks in the region have significant trade implications for the high value ornamental koi carp industry, and the important food fish common carp. Active trade in ornamental fish poses a potential risk for spread of KHV. Recognising the significance, "infection with koi herpesvirus" has been listed under "diseases prevalent in the region" in the NACA/FAO/OIE regional quarterly aquatic animal disease (QAAD) list, effective for reporting from first quarter of 2004.
