Sažetak
Four year study (May 1997 - December 2000) into reproductive biology of pink dentex Dentex gibbosus (Rafinesque) from the Adriatic Sea revealed that this species is a rudimentary hermaphrodite. The smallest captured mature males and females were 38.70 cm total length (TL) and 39.80 cm total length (TL), respectively. 50 % of population were sexually mature at 41.50 cm TL, while 100% of the specimens were sexually mature at 57.00 cm TL. Both monthly gonadosomatic index and macroscopically determined gonad stages strongly indicate that the pink dentex from the Adriatic Sea spawn partially in August, September and October. The mean value of absolute fecundity (F) was 1 672x106 eggs. Results on great fertility of the pink dentex, partial spawning and relatively late sexual maturing suggest that the pink dentex has a high potential for commercial culture.
