0.05). The maximum protein content was obtained in culture containing NH4NO3 followed by NH4Cl and KNO3, and there is not significant differences between treatments (p>0.05). Moreover, in all S. platensis cultures, increasing in nitrogen concentrations, led to an increase in maximum biomass and protein content. The chl. a content increased with increasing Nitrogen concentrations in all treatments and relatively high values (9.18 µg/ml) were found with KNO3 as a Nitrogen source at 14th day of culturing period. Overall, though the results of present studyclearly showed no significant differences between treatments, but using of NH4NO3 could have relatively more effectiveness than the other Nitrogen sources.]]>

0.05). However, the highest erythrocyte counts and hematocrit index were obtained in T2 (p<0.05). Also, the highest and lowest cholesterol content were recorded in control (279.3±1.47 mg/dl) and T2 (173.3±1.47 mg/dl), respectively (p<0.05). Results indicated that supplemented diet with 15 g algae per kg of feed can significantly reduce the liver enzymes i.e. aspartate aminotransferase, alkaline phosphatase and alanine aminotransferase (p<0.05). The highest low-density lipoprotein was obtained in control group (68.00±0.75 mg/dl) and the lowest value was observed in T2 (25.200±0.72 mg/dl) (p<0.05). Therefore,dietary supplementation of the fish diet with N. oculata at 15 g/kg of feed probably improved the blood indices and liver function. ]]>
