Abstract: The effect of Spirulina platensis on the growth and survival rate of Golden Barb fish (Puntius gelius) was investigated as a protein source in a 2 months feeding trial. S. platensis was added to the basal diet at 0% (Control), 5, 10 and 20% and fed to Golden Barb fish. The growth of Golden Barb fish was related to the level of S. platensis containing. The final weight gain, specific growth rate, feed conversion ratio of fish were affected by spirulina supplementation (p>0.05). The highest Feed Conversion Ratio (FCR), 3.55±0.10 was found in the fishes that were cultured with 20% of S. platensis. The survival rate was not affected by different amount of spirulina. The results of the present study clearly demonstrate that S. platensis could be considered as a protein source for incorporation in Golden Barb fish diets to gain more weight.
