Aquacultural Engineering Society Biofloc Technology Working Group Workshop on Biofloc Technology and Shrimp Diseases

December 9-10 2013 Saigon Exhibition and Convention Center, District 7, HoChiMinh City, Vietnam

The damage inflicted by outbreaks and spread of viral and bacterial diseases costs the aquaculture industry many billions of dollars per year Recent shrimp losses in many major producing countries have had severe economic repercussions Disease control is critical to the existence of sustainable and profitable aquaculture Recently, increasing laboratory and field observations have been reported on the use of biofloc technology (or green water and other integrated aquaculture methods) to help manage such disease outbreaks Yet, in most cases, these observations were not objectively supported, precluding the establishment of clear, reproducible and detailed conclusions The present workshop is being organized to review new scientific studies and observations on the effect of biofloc technology

on disease occurrence and on the health of shrimp and fish, to summarize field experience, to suggest further research priorities and

to propose applied strategies to minimize disease outbreaks

The workshop will take place on December 9-10 in Ho Chi Minh City, Vietnam, immediately preceeding APA13 conference A round-table discussion on Dec 10 is expected to attract a great number of aquaculture producers for information exchange and the establishment of collaboration Simultaneous translation is available

on Dec 10 for Vietnamese participants Book of abstracts either in English or Vietnamese are provided at the workshop while the proceedings will be sent to all participants via email later on
