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.

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.

An Emergency Disease Control Task Force on a Serious Disease of Koi and Common Carps in Indonesia was organised by NACA in June 2002. The Task Force conducted an emergency assessment of the disease situation in July through field and laboratory examinations of collected samples. The Task Force collected information about the disease occurrence. Koi herpes virus was detected from all case samples which indicates that it may have played a role in the observed mortalities.

Wild-harvest fisheries for live reef fish are largely over-exploited or unsustainable. Sustainable aquaculture – such as that of groupers – is one option for meeting increasing demand for reef fish as well as potentially maintaining livelihoods of coastal communities. This report draws upon secondary literature, media sources and four diverse case studies from at-risk reef fisheries, to frame a strategy for encouraging sustainable aquaculture as an alternative to destructive fishing practices. It was commissioned by the APEC Secretariat.

Sulawesi has the largest coral reef area in Indonesia, at the epicenter of worldwide marine biodiversity, but is one of the areas most threatened in Southeast Asia by destructive fishing practices. This case study reviews the potential for aquaculture to provide alternative livelihoods for fishers within the context of an integrated, community-based coastal management plan with involvement of local communities empowered to control and steward their resources so that they can conserve and utilise them sustainably.

The feasibility of integrated aquaculture in seasonal water bodies in rainfed farming areas of Eastern India was assessed in on-farm trials. Fry of Indian major carps: Catla, mrigal, rohu, common carp, and silver barb, and advanced fingerlings of Indian major carps were raised to marketable size. Key factors for the success of aquaculture in seasonal water bodies are access to credit, production enhancing inputs and water bodies that hold water for more than 120 days of the year.

This report presents an overview of the state of aquatic resources in the Philippines, its performance and importance in the Philippine economy, and explores the situation of poverty in the "aquatic resources sector." The report describes the policy environment that guides the action of key actors in the sector. A general analysis of some trends in relation to factors that keep the poor from participating and benefiting from aquatic resource management is also provided.
