The family Sparidae contains 35 genera and 112 species, distributed mainly in tropical and temperate waters of the Atlantic, Pacific and Indian oceans (Froese and Pauly, 2004). Two of these species inhabit the Argentine continental shelf: the silver porgy, Diplodus argenteus (Valenciennes 1830), and the red porgy, Pagrus pagrus (Linnaeus 1758) (Otero et al., 1982; Menni et al., 1984; Cotrina, 1986; Brankevich et al., 1990; Cousseau and Perrotta, 2000). The presence of D. argenteus in the western Atlantic has been reported from southern Florida, USA to the northern San Matías Gulf (SMG; approximately 41
S), Argentina (Menezes and Figueiredo, 1985; González, 1993; Cousseau and Perrotta, 2000). Pagrus pagrus inhabits the coasts of the eastern and western Atlantic Ocean. In the western Atlantic, it was cited from New York, USA, to the northern SMG, Argentina (Menezes and Figueiredo, 1985; Cousseau and Perrotta, 2000). In Argentina, P. pagrus sustains a commercial fishery, with landings that have oscillated between approximately 600 and 2700 tonnes over the past decade (SAGPyA-DNPyA, 2003). This species has been included as endangered in the IUCN Red List (IUCN, 2002), mainly because of overexploitation of the stocks in the southeast of the USA (Harris and McGovern, 1997; Coleman et al., 2000; Vaughan and Prager, 2002). Both species sustain recreational activities and are targeted by sport divers and spear-fishers.
