Sterilization by induced triploidy is an effective method to suppress natural reproduction and therefore its stunting effect in Nile tilapia grow-out ponds.
Environmental factors can influence the sex ratios of fishes, and this knowledge could be useful to develop all-male Nile tilapia stocks without hormones.
An approach to improve growth performance and phenotypic uniformity is the reduction of genetic variability by production of clonal Nile tilapia lines.
