Fish fed 40% spirulina performed better than those fed lower levels. At the end of the experiment, there were no significant differences between the all groups in terms of average final weights (p > 0.05). No significant differences were observed in specific growth rate, feed conversion rate and weight gain. However, there were significant differences in terms of feed conversion rate between groups (p < 0.05) and it was the highest in Group E (1.090 +/- 0.044) and the lowest in Group A (2.312 +/- 0.071). Therefore, the best growth rate (1.933 +/- 0.009) and live weight gain (0.085 +/- 0.006) were recorded in. Group E. As a result of the study, 40% spirulina supplementation in the diet for guppy has a positive effect on growth and feed conversion rates.eninfo:eu-repo/semantics/closedAccessGuppyPoecilia reticulataspirulinaSpirulina platensisgrowth performancefeed conversionArticle9913951399N/AWOS:000278298700020N/A
