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.
Culture-based fisheries (CBF) are a useful development strategy for improving the income and food security of rural communities. CBF requires minimal capital outlay, mobilising farming communities to make use of existing small dams and reservoirs for the secondary purpose of foodfish production. The objective of this project is to introduce community-based CBF to Cambodia, and to consolidate the gains of communities that have adopted CBF in Lao PDR by developing strategies to optimise the benefits under varying social, climatic and regulatory circumstances.
The objective of this project was to develop an agreed code of practice for the transboundary movement of aquatic organisms that feeds into the fisheries management strategy for the lower Mekong basin. The risks of unregulated movements include the introduction of disease agents, unwanted or invasive species and of compromising the genetic integrity of local populations. The code of practice provides guidance on risk management and mitigation measures be taken into account for live aquatic animal imports or other transfers that are part of the established commercial practice, or those related to scientific study at research facilities. The code addresses impacts relating to the movement of both exotic and indigenous species.
The code was developed in consultation with the fisheries line agencies of MRC member countries and through a regional consultation workshop that was held from 3-4 November 2014. Development of the code was funded by the Mekong River Commission.
The AFSPAN Project is a three-year initiative to improve our understanding of the role of aquaculture in food security, poverty alleviation and human nutrition. The project is developing new methodologies to quantify the impact of aquaculture in developing nations and low income food deficit countries. It will enable the efficient planning, coordination and implementation of research and development programmes supporting the sustainable expansion of aquaculture, and increasing its impact on food security, livelihoods and poverty alleviation for poor people.
