As a result of the experiment repeated twice, it was found out that the sex reversal rates among the groups were at the levels of 57.1, 69.8, 69.4, 70.9, 86.1 and 93.7%, respectively. Furthermore, it was observed that the highest sex reversal rate occurred in the group to which 60 mgMT kg(-1) feed dose was applied.eninfo:eu-repo/semantics/openAccessTilapiaOreochromis niloticussex reversal17 alpha-methyltestosteronedosespopulationArticle107853857Q3WOS:0002887168000082-s2.0-79952304734N/A
