Olive flounder Paralichthys olivaceus is one ofcommercially-important fish species, with more than 43,000 mt cultured in Jeju Island, South Korea (1). In the recent years, a number of diseases caused by bacterial, viral, and parasitic pathogens have been increased, and fish farmers have experienced substantial economic losses. Scuticociliatosis caused by histophagous opportunistic scuticociliates species belonging to the genera Uronema, Miamiensis, and Philasterides that recognized as one of the most important worldwide parasitological problems. Among Uronema marinum have resulted in severe losses in the culturing of the olive flounder farms in South Korea (1). Chemotherapy or vaccineshave been success in preventing different diseases under laboratory conditions but did not prove to be commercially viable because of their prohibitive cost of production, insufficient protection or lack of safety (2). Therefore, we report the effect of five probiotics as mixed separately in diets to investigate growth performances, feed efficiency, blood biochemistry, survival rate, and non-specific immune responses in Uronema marinum infected olive flounder on week 0, 1, 2, 4, 6, and 8. All probiotics diets significantly enhanced weight gain, feed efficiency, and high survival rate between week 6 and 8. The serum aspartate aminotransferase (GOT), alanine aminotransferase (GPT) activities, total protein (TP), glucose (GLU), superoxide anion production and serum lysozyme activity significantly enhanced in infected fish feeding with L. plantarum, L. acidophilus, and S. cerevisiae diets from week 4 to 8. The present study concluded that L. plantarum, L. acidophilus, and S. cerevisiae supplementation diets act as immunostimulants that enhance the growth, feed efficiency, blood biochemistry, survival rate, and non-specific immune responses in U. marinum infected olive flounder..
