Effect of dietary supplement of Spirulina platensis on immune indices complement and lysozyme of benny fish Mesopotamichthys sharpeyi (Günther, 1874)

Effects of different levels of spirulina dietary supplementation on some immune 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. Results indicated that the amount of complements C3, C4 and lysozyme were higher in benny fish receiving diet with 10% spirulina compared to fish being fed diet with 0% of spirulina. Amount of C3, C4 and lysozyme activity in 10% treatment were higher and showed a significant difference (P<0.05) with control treatment. The results revealed that spirulina supplementation at 10% level leads to increase indices complements and lysozyme of benny fish.
