Abstract
Aspects of the reproductive biology of the Southern Stingray, Dasyatis americana, were determined from five captive adult females and their offspring. Mean size and weight of the neonates were 238.0 ± 1.6 mm disc width and 505.9 ± 10.7 g, respectively. Litter size (n = 47), which ranged from two to 10, averaged 4.2 ± 0.3 and varied directly with maternal size and indirectly with size and weight of neonates. Gestation (n = 47) ranged from 135 days to 226 days with a mean of 175.4 ± 4.1 days.
