A good news for shrimp aquaculture stakeholders in the Asia Pacific Region that we present again to invite all of you business actors for vannamei shrimp farming to join the Workshop 2018 of Biofloc Technology For Vannamei Farming. The workshop with theme “Let Producing Health and Profitable Vannamei Shrimp By Using Biofloc Technology (BFT)” will be held  on 28-31 October 2018 at Innside Hotel, Yogyakarta, Indonesia

The workshop will bring together world’s leading experts who will present many proven solutions to reduce risk to viral and bacterial disease infections, good ecosystem balance and management in shrimp farming. It is hoped that the event will be greatly beneficial for participants to generate a wealth of information from and apply these techniques for improving shrimp production in their aquaculture enterprises.

Who should attend? 
The workshop is intended for practicing shrimp farmers, farm technicians, progressive entrepreneurs, lecturers, researchers in R & D institutions, officers of the Department of Fisheries, and enterprising aquaculture students from Indonesia and overseas.

State  of The Art
Shrimp farming industry is currently passing through a challenging phase, mostly because of disease outbreaks attributed by viral and bacterial infections (vibriosis).  These are widespread in Indonesia and are feared to take new forms across diverse farming situations. Many shrimp farmers have no clue as to how this critical situation could be controlled. To manage these and the emerging challenges, farmers at the regional level need to be updated with the latest research, and also acquire adequate expertise and practical skills to efficiently organize their resources for achieving improved production levels. In fact, biofloc technology application is one of effective and economic solutions to reduce the risk of those disease in shrimp farming so far.

Biofloc is an emerging technology in aquaculture that will enable the sectorto grow towards an environmental friendly approach. The microbial community developing in the system is able to rapidly utilize dissolved nitrogen leached from excretion of fish or shrimps and uneaten food and convert it into microbial proteins. Fish and shrimp usethese microorganisms aggregated in “flocks” as additional feed source and this reduces FCR and consequently production costs. The BFTrequiresa minimal exchange of water and it will represent and excellent opportunity for the development ofmarine and freshwater aquaculture in the KSA. Furthermore, the reduced water exchange will decrease the risk of disease introduction in the culture environment, increasing the level of biosecurity in the aquaculture operations. Microorganisms in biofloc might partially replace protein content in diets or decrease its dependence of fishmeal.

Biofloc, a very recent technology seems a very promising for stable and sustainable production as the system has self-nitrification process within culture ponds with zero water exchange (Yoram 2000, 2005a, 2005b; Yoram et al., 2012). The technology has been successfully applied commercially with shrimp (L.  vannamei)  in Belize by Belize aquaculture (McIntosh 2000a, 2000b, 2000c and 2001). It also has been applied with success in shrimp farming in Indonesia, Malaysia (Taw 2004, 2005, 2008, 2010, 2012; Taw et al. 2011).  A combination of two technologies, partial harvesting and biofloc, has been studied in northern Sumatra, Indonesia (Taw et al. 2008). A simple system incorporated with conventional autotrophic algae base considered as semi-biofloc has been successfully operated in Malaysia (Taw et al., 2013) and Myanmar (Taw and Tun, 2013).

The system has also been applied in super-intensive raceways production as high as over 10.0 kg/m2 (Moss, 2006; Samocha, 2009,). It has also been applied in shrimp broodstock production (Chime, 2011). The technology is now applied for other species of shrimps such as P. monodon (Smith 2008) and freshwater prawn Macrobrachium in India. Presently, a number of studies by major universities and private companies are using biofloc as a single cell protein source in aquafeeds.

Recent studies revealed that more than 2,000 bacterial species were found in well-developed biofloc water. Biolfocs may enhance immune activity, based on mRNA expression of six immune-related genes, ProPO1, proPO2, PPAE, ran, mas and SP1 (In-Kwon Jang, 2012). With emerging viral problems and rising costs for energy, biosecure with biofloc technology appears to be an answer for sustainable shrimp aquaculture production.

The workshop aims to provide participants with an exhaustive technical background on principles, benefits and management strategies of the biofloc technology applied to sustain shrimp farming with focus on disesaes prevention and control. A sustainable and good ecosystem balance in shrimp farming management will also be intensively discussed in the workshop.

Who is organizing the Program?
The workshop on Biofloc Technology For Vannamei Farming  is organized by the Indonesian Aquaculture Society. Indonesian Aquaculture Society (IAS), a national non-profit and independent profession organization in aquaculture established in 2001, has played a key role in developing training and education of sustainable aquaculture technologies in Indonesia. This will be the 4nd biofloc workshop program organized and hosted by IAS. The 3 previous workshops were successfully held by IAS in 2015 in Banyuwangi and Jakarta, and 2017 in Yogyakarta. The program is similarly with the intensive training program that had already been conducted by AIT (Asian Institute of Technology) on August 21-25, 2017 in Bangkok, Thailand.

Who is the Trainer?
Dr Nyan Taw. He received his Marine Biology from the University of Tasmania, Australia under Colombo Plan Fellowship. He was head of R&D of Fisheries Corporation. In 1983, he became PM for ADB IFD Project and technical counter-part for JICA projects in Myanmar. In 1988, he joined the FAO of the UN and served in aquaculture projects in Indonesia, Vietnam and the Philippines culminating the position of Chief Technical Advisor. From 1995, Dr Nyan served as Sr Advisor/Production Director at a number of locations (East Java, Central Java & Sumbawa) in Indonesia.
