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 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.
