SD is controlled by genetic and environmental factors in Nile tilapia. High temperature reduces growth performance of Nile tilapia and once applied up to 36.5oC during 10 to 30 dpf it induces sex reversal in both directions depending on the genotype.Prolonged photoperiod improve growth rate without affecting survival and sex ratio.
