Tilapia lake virus (TiLV) is an emerging virus that causes syncytial hepatitis of tilapia with mortalities of up to 90%. Recent disease outbreaks in Thai tilapia farms have been associated with high cumulative mortalities and histopathological features typical of SHT. Infection has now been confirmed. The semi-nested RT-PCR protocol described here may be used freely for non-commercial applications to detect TiLV. The authors urge laboratories in Asia to test for TiLV when abnormal tilapia mortality occurs.

Perspectives on culture-based fisheries developments in Asia

This book is the proceedings of the Regional Consultation on Culture-Based Fisheries Development in Asia, held in Siem Reap, Cambodia, 21-23rd of October 2014, under the auspices of the Australian Centre for International Agricultural Research (ACIAR), the Mekong River Commission (MRC) and the Network of Aquaculture Centres in Asia-Pacific (NACA). The consultation was jointly organised by NACA and the Fisheries Administration of the Royal Government of Cambodia.

Food and nutritional security remains problematic in many developing countries. There are many initiatives underway which are designed to increase food supply, employment and income opportunities, most of which require considerable capital inputs (for instance cropping, livestock production and aquaculture). Often overlooked, are the opportunities to produce more food from the natural productive ecology of lakes and forests. Culture-based fisheries are one example of a relatively simple and low cost technology which can deliver nutritional and economic benefits to communities which often have few livelihood options.

National Fish Day, Cambodia

Inland aquaculture

NACA was privileged to have the opportunity to attend the National Fish Day celebrations in Cambodia, held at the Kdol Reservoir in Kampol Chhnange Province on 1 July and organised by the Fisheries Administration. Approximately 10,000 people attended the ceremony, including many school children and villagers from surrounding areas, which was presided over by Prime Minister Hun Sen. The Director General of the Fisheries Administration gave a report on fisheries and aquaculture development over the past year. This was followed by a speech by the Prime Minister who spoke at length about recent changes to fisheries laws including the replacement of the fishing lot system with an open access fishing regime in inland waters and the need to observe conservation measures such as respecting closed seasons to allow fish to breed, the protection of conservation areas and bans on illegal types of fishing gear.

Culture-based fisheries development in Lao PDR and Cambodia proceeding well

LivelihoodsInland aquaculture

Under the ACIAR-funded project Culture-based fisheries development in Lao PDR and Cambodia, a monitoring team recently visited both countries to observe progress by participating community groups and to provide guidance for the next stocking season. The project is working with rural villages to implement culture-based fisheries as a community activity, where the work, management and benefits are shared by local residents.

Culture-based fisheries exchanges between Lao PDR and Cambodia

Under the ACIAR-funded project Culture-based fisheries development in Lao PDR and Cambodia a team from the Cambodian side of the project travelled to Lao PDR from 8-12 May. The exchange visits between the researchers and selected community leaders of both countries are a major component of the project, expected to facilitate networking and communication between the teams and to bring about an interchange of ideas and lessons learned.

The specific purpose of the visit was to apprise the Cambodian team of the culture-based fisheries activities that have been on-going in Lao PDR for the past five years, including aspects of community-based management of common water bodies. The exchange visit included field visits to reservoirs practicing culture-based fisheries, lectures from Lao project team members and interaction with community leaders.
