2 BACKGROUNDShrimp (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 days2. 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 hoursCrustacean are carrier (crabs) – lives with virus.6. Virus lives in freshly dead, indefinitely in fresh processed frozen conditionVirus can live and a very few can survive after mass mortalityNo evident of wind carrying WSSV from pond to pond9. Bacteria white patch (spots) on carapace can be mistaken as WSSV spots.
