Udang vaname (Litopenaeus vannamei) merupakan komoditas ekspor uta-ma Indonesia, namun proses pembenihannya sering terkendala penyakit vibriosis akibat infeksi Vibrio sp. yang dapat menyebabkan kematian massal pada stadia larva. Penggunaan probiotik, baik single spesies maupun multi spesies, berpotensi menekan patogen, memperbaiki kualitas air, dan meningkatkan performa pertum-buhan. Penelitian ini bertujuan mengevaluasi pengaruh pemberian probiotik ber-beda terhadap total Vibrio sp. dan performa pertumbuhan post larva udang vana-me. Penelitian menggunakan Rancangan Acak Lengkap dengan tiga perlakuan dan empat ulangan, yaitu P1 (tanpa probiotik), P2 (probiotik single spesies Bacillus sp.), dan P3 (probiotik multi spesies Bacillus sp., Lactobacillus sp., Enterococcus sp., dan Pediococcus sp.). Post larva 1 (PL1) dipelihara selama 12 hari dengan kepadatan 50 ekor/L, dan probiotik diberikan setiap hari dengan dosis 3 ppm. Parameter yang diamati meliputi Total Vibrio Count (TVC) pada media dan tubuh udang, pertumbuhan panjang, lipid droplet, tingkat kelangsungan hi-dup, dan kualitas air. Hasil menunjukkan bahwa probiotik multi spesies secara sig-nifikan (P<0,05) paling efektif menekan pertumbuhan Vibrio sp. pada tubuh u-dang, serta menghasilkan pertumbuhan panjang mutlak dan akumulasi lipid droplet tertinggi. Meskipun TVC pada P2 dan P3 tidak berbeda nyata pada media pemeliharaan dan SR tidak berbeda nyata antar perlakuan. Selain itu, perlakuan P3 lebih efektif dalam menjaga stabilitas kualitas air. Kesimpulannya, penambah-an probiotik, khususnya multi spesies, efektif dalam meningkatkan performa per-tumbuhan dan menekan pertumbuhan Vibrio sp. pada post larva udang vaname. Kata Kunci: Multi Spesies, Probiotik, Single Spesies, Udang Vaname, Vibrio sp. Litopenaeus vannamei is one of Indonesia’s primary export commodities; however, hatchery production is frequently constrained by vibriosis caused by Vibrio sp. infection, which can lead to mass mortality during the larval stages. The application of probiotics, either as single-species or multi-species formulations, has the potential to suppress pathogenic bacteria, improve water quality, and en-hance growth performance. This study aimed to evaluate the effects of different probiotic treatments on total Vibrio sp. and the growth performance of post-larval whiteleg shrimp. The experiment employed a Completely Randomized Design with three treatments and four replicates: P1 (without probiotic), P2 (single-spe-cies probiotic Bacillus sp.), and P3 (multi-species probiotic consisting of Bacillus sp., Lactobacillus sp., Enterococcus sp., and Pediococcus sp.). Post-larvae stage 1 (PL1) were reared for 12 days at a density of 50 individuals L⁻¹, and probiotics were administered daily at a dose of 3 ppm. Observed parameters included Total Vibrio Count (TVC) in the rearing water and shrimp body, absolute length growth, lipid droplet accumulation, Survival Rate (SR), and water quality. The results indicated that the multi-species probiotic treatment significantly (P < 0,05) reduced Vibrio sp. levels in the shrimp body and produced the highest absolute length growth and lipid droplet accumulation. Although TVC in the rearing water between P2 and P3 was not significantly different, and SR did not differ signific-antly among treatments, the multi-species probiotic was more effective in main-taining water quality stability. In conclusion, probiotic supplementation, particu-larly multi-species formulations, effectively enhances growth performance and suppresses Vibrio proliferation in post-larval whiteleg shrimp. Keywords: Multi-Species, Probiotic, Single-Species, Vibrio sp.,Whiteleg Shrimp.
