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.
The project made use of the significant results from the JICA projects in Cambodia, Benin and other countries on farmer-to-farmer extension approaches on technology extension for small-scale farmers. This also integrated other approaches of technology extension such as cluster farming which was also proven effective for small-scale farmers, in terms of application of farming technologies and aquaculture standards. The guidebook will introduce good practices on aquaculture extension not only to Asian countries but also to African countries.
This project utilised the vast experience of NACA and JICA on sustainable aquaculture projects in the region towards the formulation of a simple but efficient guidebook which can be used in developing a practical training course module on the above subject.
The objectives of this project were to i) develop a guidebook in English on "Farmer-to-farmer extension approaches for small-scale aquaculture" and ii) to translate the developed guidebook into selected local dialects in Asia-Pacific and other regions (e.g. Africa).
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.
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.
