This study aims to determine the effect of the administration of bacteriaisolated from shrimp pond sediment Bacillus mycoides, B.subtilis , and Pseudomonas diminuta towardsplankton abundance, N/P ratio, and total bacteria in the culture media of whiteshrimp ( Litopenaeus vannamei ). This experimental research usinga Completely Randomized Design (CRD) consisting of four treatments based on thedifference in the bacterial density, namely K(0 cell/mL), B1 (10 6 cells/mL), B2 (10 7 cells/mL), and B3 (10 8 cells/mL), withfour replications each treatment and the shrimps were carried out for 28 days.The parameters were observed are plankton abundance, N/P ratio, and totalbacteria. This research showed that probiotics could increase planktonabundance, N/P ratio, and total bacteria. The results of this research indicatethat the different density of bacteria from shrimp pond sediment significantlydifferent (p<0,05) towards plankton abundance and total bacteria in theculture media of white shrimp, while the administration of bacteria from shrimppond sediment could increase the N/P ratio. The B3 gave the best results onplankton abundance, N/P ratio, and total bacteria of 13,566.88cells/mm 3 , 7.22, and 2.93 x 10 9 cells/mLrespectively.
