“…The smallnose fanskate, Sympterygia bonapartii Müller & Henle, 1841, occurs regularly from off Santos, Brazil (24° S, Menni, Stehmann, 2000) to Santa Cruz Province, Argentina (49° S, Cousseau et al, 2007), from the intertidal to 100 m deep (Menni, Stehmann, 2000). The reproductive biology of S. bonapartii has been extensively studied and parameters such as size at maturity and fecundity are well known (Mabragaña et al, 2002;Oddone, Velasco, 2004;Oddone, Vooren, 2008;Galíndez et al, 2010;Díaz-Andrade et al, 2013;Basallo, Oddone, 2014;Moya et al, 2015;Estalles et al, 2017). Recently, growth parameters and age at maturity of this species in the wild have been estimated (Hozbor, Massa, 2015).…”
