“…DDT, PCB). This hypothesis is 3 supported by abnormal VTG production being found in males of two other top predators, tuna (Thunnus thynnus) and swordfish (Xiphias gladius), that inhabit pelagic environments even further from shore (Fossi, Casini, Ancora, Moscatelli, Ausili, & Notarbartolo-di-Sciara, 2001;Fossi, Casini, Marsili, Neri, Mori, Ancora et al, 2002;De Metrio, Corriero, Desantis, Zubani, Cirillo, Deflorio et al, 2003;Fossi, Casini, Marsili, Ancora, Mori, Neri et al, 2004;Desantis, Corriero, Cirillo, Deflorio, Brill, Griffiths et al, 2005). Furthermore, in tuna, it also appears that the larger fish have higher VTG production (Barucca, Canapa, Olmo, & Regoli, 2006).…”
