Disease in shrimp culture can cause a decrease in the production of even death in the culture business. Alternative prevention currently is mostly done through immunoprofilaksis shrimp that improves immunity against the disease by administering such immunostimulan bacterin vaccines and recombinant vaccines.

This study aims was to determine the survival rate and the production of tiger shrimp culture in ponds with bacterin application. Using a completely randomized design with 4 treatment here namely: A = fries and parent were not in the vaccine, B = fries are not in the vaccine of the parent in the vaccine, C = fries in the vaccine of the parent is not in the vaccine and D = fries are not in the vaccine from the parent not in vaccine (control) were each repeated 2 times, the stocking density 5 fries/m2 PL 12 in the ponds of 250 m2. Shrimp used are submersion with bacterin for 45 minutes before stocked. During the administration of bacterin maintenance is done through the mixed feed before pelleting + vitamin C 0.05 ppm + binder with a dose of 5 g / kg of feed. Vaccination is done 2x a month on the day to 10-12 (regular feed), days 13-15 (feed mixed bacterin), days 25-27 (regular feed) as well as the day to 28-30 (feed mixed bacterin) feed , Applications dolomite done 2 times per week with a dose of 2-5 ppm after water exchange began when stocking until harvest. Results showed treatment of parent chicks in vaccines in the vaccine produces survival rate (75.7%) were better, while for production (450 kg / ha) which is the best result of treatment of parent chicks in the vaccine is not in the vaccine. Total bacteria Vibrio (TBV) in sediments 102-104 CFU/g and the pond water 102 CFU/mL in range. The quality of water was in good condition for the tiger shrimp culture, while NO2-N (mg/L) at 5 sampling period (for 70 days) showed a significant increase but then declined until the end of the experiment.
