To know the effectivity of powder-formed probiotics compared to the liquid-formed probiotics t-test experiment was carried out in the Marana Experimental Pond Installation of the Research Institute for Coastal Aquaculture and Fisheries Extension, Maros. Ten 250-m2 concrete-wall ponds with 80 cm water depth and aerated with supercharge blower were stocked with 8 pcs of tiger shrimp post larvae/m2. Treatments tested here were A) The liquid-formed of alternate use of Bacillus subtilis BM12, B. licheniformes BM58, and Brevibacillus laterosporus BT951 and B) The powder-formed of alternate use of Bacillus subtilis BM12, B. licheniformes BM58, and Brevibacillus laterosporus BT951. There were five replications in each treatment. After 67 days of culture showed that the use of powder-formed probiotics tended to be better than the use of the liquid ones, even though not significantly different (P>0.05). The average production and survival rate of powder-formed probiotics were 430.4 + 37.6 kg/ha and 72.1 + 9.8%, while those of the liquid-formed probiotics were 385.6 + 73.6 kg/ha and 66.6 + 10.8%. Both forms of probiotics could effectively maintain water quality parameters like total organic matter, NH3-N, NO2-N, and TBV/TPC ratio.
