PERFORMA PRODUKSI UDANG VANAME (LITOPENAEUS VANNAMEI) YANG DIBUDIDAYAKAN PADA TAMBAK SISTEM SEMI INTENSIF DENGAN APLIKASI PROBIOTIK
ABSTRACT: The aimed of this
research to effect probiotics influented on the growth, survival rates,
production, productivity and FCR and water quality condition of Pacific white
shrimp L. vannamei in pond under semi intensif system. Six of pond compartments
each sized 2,000 m2 were stocked with PL-12 at the density of 15 fries/m2. Two
treatmens of probiotics application in pond were tested, there were A). 0 mg/L
probiotic and B).1.5 mg/L fermentation of probiotic. Each treatment was done in
three replicated. On treatment probiotic applied weekly to the ponds started on
the first week before shrimp stocking until harvested, while in treatment B
probiotic application was mixedwith feed pelled then it was given to the
cultured shrimp in the ponds. Result of the research showed that final shrimp
body weight in treatment B tend to be higher compared to the treatment A.
Absolut shrimp growth-rate in treatment B: 20.727 ± 0.042 g and treatment A
:15.7 ± 0.016 g, Shrimp survival rate treatment A 0.432±0.0003 and treatment B
: 0.79±0.0145. Production-rate of shrimp in treatment A: 203.627±0.083 kg/2000
m2 and treatment B : 504.489 kg/200 m2. Productivity of shrimp in treatment A :
0.1 kg/m2/period of plants dan perlakuan B: 0.25 kg/m2/period of plants. FCR of
shrimp in treatment A 1.79±0.005 and treatment B : 1.42±0.003. Probiotics used
in treatment B resulted in the enchancement of water quality condition (total
organic matter, nitrat) compared to the treatment A ( 0 probiotics). This
condition presumably resulted the highest shrimp production in treatment A.
