Abstract
Feminization was achieved in the fighting fish, Betta splendens, by treating 3-day old fry with 20 mg diethylstilbesterol, 50 mg 17 alpha -ethynylestradiol or 125 mg beta -estradiol per kg food for 40 days. Sex reversed heterogametic females (XY) were identified by progeny testing. Eggs collected from these females were activated with UV irradiated Oreochromis mossambicus sperm and subjected to pressure shock at 7000 psi for 6 min to induce diploidy. However, the YY males of B. splendens were not viable and succumbed before hatching.
