affect overall survival, FCR or tilapia growth. Tilapia did not show intraspecific
competition in the different treatments, because feeding of commercial formulated diet for tilapia was adjusted to the biomass of each tank, so there were no differences in feed availability for this species among treatments. The presence of the Mayan cichlid in different proportions did not affect tilapia performance (survival, growth and CF) and did not affect the growth of tilapia males or females. This shows that the Mayan cichlid, under the tested size and proportions, can be grown in polyculture with tilapia with no negative effects on its performance.
