2 Shrimp (L. vannamei) farming has become competitive and as such technology starting from biosecure farm design and operation system utilized is essential for sustainable production. This has been proven by re-engineering from pond base culture to module base biosecure system at a large shrimp farm in Indonesia (Nyan Taw et.al., 2007). The basic concept of biofloc technology was provided by Avnimelech (2000, 2005a&b). The system was successfully applied in commercial culture of shrimps by McIntosh (2000a, b & c, 2001), McNeil (2000), Nyan Taw (2004, 2005, 2008 & 2010). Smith et al (2007) successfully used biofloc technology on Penaeus monodon in earthen ponds in Australia. Shrimp farm biosecurity was given by Nyan Taw (2010). Successful redesigning and production using biosecurity and biofloc technology was also provided very recently by Nyan Taw (2011). Blue Archipelago intensive shrimp farm, Arca Biru SDN, is located at Kedah, northwest of Kuala Lumpur. The farm was established in early 1990s for Penaeus monodon culture. However, the farm was faced with serious viral (WSSV) outbreaks. In early 2010, the farm was re-designed from pond base to biosecure module base system including two modules lined with HDPE. For the remaining modules, only pond dikes were lined. The farm was operated with minimum water exchange, semi- biofloc and biofloc technology. The main objective of the cycle was to have a bench-mark for future production cycles as such a number of commercial trials were tried. BACKGROUND

Recirculation system 1999 NT Dec09 Dipasena Pond base in rows changed to Module base operation system in 2006 – reservoirs and culture ponds Pond Base in rows Module Base system Dipasena WM Module Base system Nyan Taw WAS 2005 Bali Farmer session Nyan Taw, Shrimp Farm Indo GAA 2005 Nyan Taw et al Reengineering Dipasena GAA 2008 THE CHANGES

5 Before Re-designing – Module ? Biosecurity ? Sub Inlet gate - leaks SI Canal –cannot dry Nets – 1000 micron Out let gates - Leaks Sludge center pond – not removed Crab fence – not maintainted Dead WSSV shrimps after harvest – not removed Not used Crabs Out let leaks Black sludge now removing Bird scare lines Fish Nets – 1000 micron ? Reservoir pond Nets – 1000 micron

6 What we are protecting from ? Basic WSSV Characters 1.Mass mortality: DOC <45 days 2.Temperature >30 less prone; <29 more prone; <26 dangerous. 3.Onset of heavy rain (season) with low temperature trigger outbreaks. Seasonal occurrence is well document. 4.Virus dies in free water in 72 hours 5.Crustacean are carrier (crabs) – lives with virus. 6.Virus lives in freshly dead, indefinitely in fresh processed frozen condition 7.Virus can live and a very few can survive after mass mortality 8.No evident of wind carrying WSSV from pond to pond 9.Bacteria white patch (spots) on carapace can be mistaken as WSSV spots. BIOSECURITY

8 Bio-secure Module system – Arca Biru

9 Arca Biru, Malaysia Biosecure module - after re-designed 250 & 1000 micron screen net HDPE Lined secondary supply canal Biosecurity – crab fence & bird scare lines HDPE lined ponds with center drain, secured outlet gates & Main supply canal Sub inlet Pond out let gate

10 Physical barrier for viral carriers – use 250 micron screen net Chemical application – kill viral carriers. Apply crusticides Kill free water bore virus (aging) - dies in 72 hrs without host Treated water ready for use for culture (apply same procedure) Module Biosecurity – Water treatment system (Control WSSV) Treatment Reservoirs ponds Culture ponds

12 Basic of BFT in Shrimp Farming 1. High stocking density - over 130 – 150 PL10/m2 2. High aeration – 28 to 32 HP/ha PWAs 3. Paddle wheel position in ponds 4. HDPE / Concrete lined ponds 5. Grain (pellet) 6. Molasses 7 C&N ratio >15 8. Biofloc controled at <15 ml/L 9. Expected production 20–25 MT/ha/crop Bioflocs High density High aeration Dark VannameiRed Vannamei Grain pellet Feed & grain application and biofloc Biofloc
