Abstract
Feminization was obtained in Betta splendens by the oral administration of 125 mg beta -estradiol per kg food. The shortest period during which 100% feminization could be achieved was 40 days beginning from the first feeding. Progeny testing confirmed the completeness of sex reversal. Eggs (2.5 min old) from sex-reversed females were pressure shocked at 7000 psi for 6 min to induce all-male, less aggressive triploids with an average survival of 45%. Our results provide evidence for male heterogamety in B. splendens.
