Popis: ABSTRACT This study aimed to investigate the effectiveness of synbiotic (prebiotic alginate and probiotic bacteria Micrococcus spp) on the immune responses, growth performance, and bacterial resistance of freshwater crayfish. The experimental diets were formulated in three levels of synbiotic: the probiotic bacteria Micrococcus spp+100 mg/L alginate (Syn100), Micrococcus spp+200 mg/L alginate (Syn200), Micrococcus spp+300 mg/L alginate (Syn300), each level was mixed with tested feed. The basal diet (without synbiotics) served as the control diet. During 40 days of rearing, immune responses observations were conducted every 10 days, while the crayfish weight were recorded on day 40. Furthermore, the challenge test was performed against the pathogenic bacteria of A. hydrophila and reared for a week. The result showed that synbiotics treatment of Syn300 and Syn200 could improve the immune response and increased the growth rate (P
