Fish were fed daily ad libitum with diets containing 0.5% and 1.0% tetra for 3 weeks. After this period, fish were switched back to the basal diet for additional 6 weeks. Extracellular and intracellular respiratory burst activities, phagocytosis in blood leukocytes, lysozyme activities, and total plasma protein levels were evaluated at the end of the tetra feeding period and every 3 weeks during the basal diet period. Extracellular and intracellular respiratory burst activities, phagocytic activity, lysozyme activity and total protein level parameters of the groups containing 0.5% and 1.0% tetra were higher than the control group at the end of the 3rd, 6th and 9th weeks, respectively (P < 0.05). The highest values of the non-specific immune parameters were observed in the group fed with 1.0% tetra. Tetra groups did not show any significant difference (P > 0.05) in terms of specific growth rate and average weight of the fish.
