Abstract
This study is aimed to determine the role of the use of antibiotics and probiotics in controlling water quality maintenance, growth and survival of shrimp larvae. This study was an experimental study with application of 1 ppm Oxytetracyclin antibiotic and probiotic bacillus at a dose of 0.75 ppm, 1 ppm and 1.25 ppm. Test animals used were shrimp larvae PL-5 which were maintained in 60 L plastic container volume and 9 days after maintenance carried out sampling and day 14 in the total harvest. Biological study of shrimps were tested include growth and survival. Results showed media for maintenance of water quality such as temperature, salinity, pH, oxygen ppm, NH3, nitrite, nitrate, and BOT has a value that can be tolerated for the life of shrimp larvae. Furthermore, growth at the end of the study showed that the highest growth was obtained on treatment B 0.128 g, followed by 0.089 g treatment A, treatment C was 0.074g and the lowest growth in the D treatment (control) of 0.010 gr. While the highest survival rate of shrimp test animals highest in treatment C was 84.8%, followed by 78.6% D treatment, treatment A was 78.4% and 77.2% for treatment B.
