Dab (Limanda limanda) ovarian fragments were incubated in vitro with either [4,7-3H]pregnenolone or 17 alpha-hydroxy[1,2,6,7-3H]progesterone to investigate the pattern of steroidogenesis. A major enzyme found in the dab ovary was 20 alpha-hydroxysteroid dehydrogenase. Among the steroids that were tentatively identified
