CLUSTER MODEL FOR EXTENSIVE GIANT TIGER SHRIMP (Penaeus monodon Fab.) TO PREVENT TRANSMISSION OF WHITE SPOT SYNDROME VIRUS
Abstract: White spot syndrome
virus (WSSV) has become epidemic in Indonesia and affecting shrimp aquaculture
interm of its production. White spot syndrome virus is transmitted from one to
other ponds, through crustacean, included planktonic copepode as carrier for
WSSV and through water from affected shrimp pond. A cluster model, consist of
shrimp grow out ponds surrounded by non-shrimp pond as a role of biosecurity
has been developed. The model aimed to prevent white spot virus transmission in
extensive giant tiger shrimp pond. The study was conducted in two sites at
Demak District, Central Java Province. As the treatment, a cluster consist of
three shrimp ponds in site I, and two shrimp ponds in site II, each was
surrounded by buffer ponds rearing only finfish. As the control, five extensive
shrimp grow out ponds in site I and three shrimp grow out ponds in site II,
with shrimp pond has neither applied biosecurity nor surrounded by non-shrimp
pond as biosecurity as well considered as control ponds. The results found that
treatment of cluster shrimp ponds surrounded by non-shrimp ponds could hold
shrimp at duration of culture in the grow out pond (DOC) 105.6±4.5 days
significantly much longer than that of control that harvested at 60.9±16.0 days
due to WSSV outbreak. Survival rate in trial ponds was 77.6±3.6%, significantly
higher than that of control at 22.6±15.8%. Shrimp production in treatment ponds
has total production of 425.1±146.6 kg/ha significantly higher than that of
control that could only produced 54.5±47.6 kg/ha. Implementation of Better
Management Practices (BMP) by arranging shrimp ponds in cluster and surrounding
by non-shrimp ponds proven effectively prevent WSSV transmission from
traditional shrimp ponds in surrounding area.
