Verification and Pilot Demonstration
Verification and pilot demonstration activities were implemented
in 2000 with the aim of dissemination mangrove-friendly shrimp
culture technology through actual demonstration in order to
determine whether techniques known to be successful in a particular
country or area can be adopted in other countries or lacations
as well. The activities were implemented at AQD's Dumangas Brackiswater
Station (DBS) in Iloilo, Philippines; in Phu Long Island, Cat
Hai District, Hai Phong, Vietnam; and in four sites in Thailand,
namely, at Kung Krabaen Bay, Chantaburi; in Songlhla; at Gangkapong
District, Chachaengsao; and in Phuket.
Recent approaches for sustainable shrimp farming, DBS, Iloilo,
Philippines
| Approached for shrimp farming have
been developed by AQD based on results of verification
studies it had conducted in other sited in the Philippines
specifically on growth, survival and production of the
tiger shrimp, Penaeus Monodon using environment-friendly
schemes. These approaches which include crop rotation;
the use of partial and/or zero discharge system; the use
of probiotics, bio-augmentation or microbial inoculants;
and the use of low salinity levels for shrimp culture,
led to the development of techniques that are useful in
arresting the occurrence of luminous bacteria. However,
the need for further refinement of the techniques for
packaging and dissemination was recognized. The activity
at DBS is therefore intended to refine such techniques.

Two runs of sustainable shrimp farming
at DBS conducted in Year 2000 using two ponds (0.9 ha
and 0.8 ha) stocked at 40m-? and 60 m-?, respectively,
were harvested after 150 days culture. Production averaged
at 5.0 tons/pond. Although results in 2000 were very promising,
there is still a need to refine further the closed recirculating
system for intensive shrimp farming, and this will be
the focus of the activity at DBS in 2001.
