2. BACKGROUND
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.

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

2 Module HDPE Module HDPE At Dyke Module LDPE At Dyke – 9 modules
Operated only 1 Module HDPE + 6 Modules HDPE at Dike – 7 modules

10. Module Biosecurity – Water treatment system
(Control WSSV)
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)
Treatment Reservoirs ponds
Culture ponds

11. Module Base Close Water System

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
