Abstract
    Effect of different levels of spirulina dietary supplementation on some blood-immune parameters and serum biochemical parameters of Benny Mesopotamichthys sharpeyi  fingerlings were investigated in an 8 weeks experimental period. Dried and powdered spirulina algae in five levels of 0, 2.5, 5.0, 7.5 and 10.0 % was added to the experimental diet. Experimental fish were fed to satiation twice daily. Haemato-immunological and blood serum biochemical parameters were higher in benny fish receiving diet with 10% spirulina compared to fish being fed diet with 0% of spirulina. Haematological parameters and blood serum biochemical parameters including haemoglobin concentration, haematocrit, total protein, total albumin, total globulin and albumin/globulin ratio were not significantly (P>0.05) affected by spirulina supplementation. However, lysozyme activity levels in 10% treatment were higher and showed a significant difference (P<0.05) from control treatment. The results revealed that spirulina supplementation at 10% level leads to improve haemato-immunological and serum biochemical parameters of benny fish.
