• Feeding habits and trophic levels of bluefin tuna Thunnus thynnus of different size classes in the Mediterranean Sea (2007, background): “Adult tuna come through the Gibraltar Strait from the eastern Atlantic population (Medina et al., 2002), reaching their Mediterranean spawning grounds inMay, where they stay only until late July (Corriero et al.”
• Histological investigation on the ovarian cycle of the bluefin tuna in the western and central Mediterranean (2003, methodology): “Considering that the presence of vitellogenic oocytes is a sign of sexual maturity (Lowerre-Barbieri et al., 1996; Arocha, 2002; Medina et al., 2002), all the fish 110 cm LF, caught from mid-May to early July, could be considered mature (Table I).”
• Lipids in female northern bluefin tuna (Thunnus thynnus thynnus L.) during sexual maturation (2001, background): “Medina et al. (2002) have determined an average batch fecundity of 92.8 oocytes per g of body mass indicating an average female bluefin tuna of 150 kg can produce about 8.6 kg of mature ovaries.”
• Atlantic bluefin tuna: population dynamics, ecology, fisheries and management (2005, background): “ABFT appear to spawn when they reached specific locations (Rodriguez-Roda 1964; 1967), which has been supported by recent studies (Medina et al. 2002).”
• Size and age at sexual maturity of female bluefin tuna (Thunnus thynnus L. 1758) from the Mediterranean Sea (2005, background): “…Florida straits in April–July (Richards, 1976; Montolio and Juarez, 1977; Rivas, 1978; Baglin, 1982), whereas the eastern Atlantic population spawns in the Mediterranean during May–July (Rodrı́guez-Roda, 1967; Susca et al., 2001; Medina et al., 2002; Corriero et al., 2003; Karakulak et al., 2004).”
• Atlantic Bluefin Tuna (Thunnus Thynnus) Farming and Fattening in the Mediterranean Sea (2010, background): “, 2004), and the major spawning areas have been identified around the Balearic Islands (Spain), south of Malta, the South Tyrrhenian Sea (Italy), and the Levantine Sea between Turkey and Cyprus (Nishida et al., 1997; Medina et al., 2002; Corriero et al., 2003; Karakulak et al., 2004; Heinisch et al.”
• Predicting the occurrence of Atlantic bluefin tuna (Thunnus thynnus) larvae in the northern Gulf of Mexico: building a classification model from archival data (2010, background): “Adult bluefin tuna are capable of detecting and responding to oceanographic gradients (Medina et al., 2002; Royer et al., 2004; Wilson et al., 2005), and Richards et al.”
• Geographically and environmentally driven spawning distributions of tuna species in the western Mediterranean Sea (2012, background): “The prevalence of the time of spawning of bluefin tuna from mid-June to early July in the Balearic Islands has been well documented (Medina et al. 2002, Corriero et al. 2003).”
• Evolutionary and ecological constraints of fish spawning habitats (2015, background): “For example, Atlantic bluefin tuna has very high fecundity ( 90 oocytes per gram) and asynchronous ovarian development, whereby all different stages of oocyte maturation are found at any given time in the ovary (Medina et al., 2002).”
• Life History and Stock Structure of Atlantic Bluefin Tuna (Thunnus thynnus) (2007, background): “Active non-spawning individuals have been observed in May, with yolked oocytes in the ovaries and seminiferous lobules progressively filled with spermatozoa (Figure 2A).”
