Using Bioflocs and Tilapia to Fend Off EMS


According to The Vietnam Association of Seafood Exporters and Processors (VASEP), early mortality syndrome (EMS) cost shrimp farmers $1.4 billion in losses in 2012.  In 2013, however, the loss has been reduced thanks to the implementation biofloc technology (BFT).  In addition to BFT, some provinces have implemented polyculture of shrimp and tilapia that has proved effective in combatting EMS. Minh Phu Corp, an important farmer and big shrimp exporter, used BFT to combat EMS, and in 2013, it polycultured 20 hectares shrimp and tilapia.  Accordingly to VASEP, shrimp mortalities from EMS were reduced “remarkably” when shrimp were polycultured with tilapia.


In 2013, some shrimp farmers in Soc Trang Province (Mekong Delta) polycultured shrimp with red snapper, and shrimp mortalities fell significantly.


The use of BFT technology in China and Thailand is also proving effective against EMS, said VASEP.
