Abstract
Abstract. To see if three bacteria probiotics of Bacillus subtilis, B. licheniformis, and Pseudoalteromonas sp Edeep-1 can be used for vannamei culture in the extensive pond, twelve ponds located in Suppa district of Pinrang regency were used. Each pond of about 0.5 ha was stocked with 30,000 pcs of vannamei shrimp postlarvae. Applications tested here were A) The standard probiotics (Brevibacillus laterosporus BT951, Serratia marcescens MY1112, and Pseudoalteromonas sp Edeep-1 BL542- B) The replacement probiotics (Bacillus subtilis BM12, B. licheniformis BM58, and Pseudoalteromonas sp Edeep-1 BL542)- and C) Single use of Brevibacillus laterosporus BT951. There were four replications in each treatment with a culture period was three months. Pond water quality parameters were monitored every two weeks and analyzed at the Research Institute for Coastal Aquaculture and Fisheries Extension Laboratory in Maros, South Sulawesi. The results showed that the survival rate of the shrimp in treatment B was significantly better (P<0.05) than the others. However, shrimp production was not quite different (P>0.05) between A and B treatments. It is concluded that replacement probiotics could be used if the standard probiotic is not available.
