Abstract: The high availability of mango that is discarded from what could be destinated for human consumption generate waste. Therefore, it can be used as ingredient for fish feed. The objective of this study was to evaluate the mango flour effect on tilapia performance and metabolism. It used 180 tilapia with initial average weight of 4.69g that were randomly divided into 12 experimental units 500L. Four diets were tested with different proportions of corn meal replacement by mango flour (0%, 33%, 66% and 100%). The feeding period was 45 days and feeding rate was 6% of the biomass. A reduction in fish performance (p <.05) and feed efficiency was observed in treatments with levels above 66% inclusion of mango flour. Fish hepatosomatic index and hepatic glycogen increased in groups 100% of mango meal inclusion. Glucose, free amino acids and total enzyme activity of liver oxaloacetic transaminase increased 100% of mango meal. Plasma total protein, total cholesterol and transaminase oxaloacetic enzyme activity did not change. It was concluded that replacing corn bran by mango meal up to 33% increased tilapia performance.
