DOI : 10.4194/AQUAST1163 Viewed : 1181 - Downloaded : 1212 In this study, the effect of borage (Borago officinalis) powder on juveniles of common carp (Cyprinus carpio) were investigated. The diets contained control (0), 0.5%, 1.5%, and 2.5% of borage powder. The fish with the initial average weight of 8.40 ± 1.37 were allotted to 12 circular tanks of 300 L capacity at a density of ten fish per each tank and fed to apparent satiety three times a day. The growth performance of the fish showed no significant difference compared to the control group (P > 0.05). By adding 1.5% borage powder to the control diet the mucosal immunity of fish in terms of lysozyme activity (14.26%), total protein (69.64%), immunoglobulin (30.78%), and humoral immunity in term of lysozyme activity (9.7%), complement components C3 (8.27%), C4 (21.64%), and total protein (9.33%) were increased significantly (P < 0.05). A total number of red blood cell (12.39%), mean corpuscular volume (MCV, 8.99%), mean corpuscular hemoglobin (MCH, 10.22%), and hemoglobin (2.69%) showed a significant increase in the fish fed supplemented diet with 1.5% borage powder compared to the control (P < 0.05). The results showed supplemented diet with 1.5% dietary borage powder induced high immunity and survival rate of juvenile common carp. Keywords : Hematology Herb Immunity Proximate composition
