Abstract
Aspects of the reproductive biology are described for the thorny stingray, Dasyatis centroura, caught off the coasts of Tunis, mainly from the Gulfs of Gabes and Tunis. Sexual maturity in males occurs at a disk width (DW) of 800mm. Female maturation occurs between 660mm and 1000mm DW. All males and females having a DW greater than 800 and 1000 mm, respectively, were adults. Females are larger than males, with adult specimens having an average DW of 1040mm in males and 1345mm in females. Gestation lasts for a minimum of about 4 months. The number of reproductive cycles per year is unknown. Vitellogenesis is completed at the end of the gestation. Parturition and ovulation occur in June. Fecundity ranges from 2 to 6 individuals per litter.Key wordsSexual maturitySize at maturityReproductive cycleFecundityMediterraneanGulf of Gabes
