Variations in the diet and stable isotope ratios during the ovarian development of female yellowfin tuna (Thunnus albacares) in the Western Indian Ocean

Energy allocation strategy of skipjack tuna Katsuwonus pelamis during their reproductive cycle

“…This strategy has already been described in large tropical pelagic fishes, for example, T. albacares , where feeding and spawning activities were observed to occur in the same time and area strata (McPherson, ; Itano, ; Bard et al ., ; Zudaire et al ., 2013 b ; Sardenne et al ., ). For T. albacares , egg production increased in response to increasing daily rations (Margulies et al ., ; Zudaire et al ., ). Katsuwonus pelamis appears to use a breeding strategy that more closely aligns to income breeding than T. albacares (Zudaire et al ., ).…”

Feeding strategies and ecological roles of three predatory pelagic fish in the western Mediterranean Sea

“…Stable Isotope Analysis in R [SIAR] isotopic mixing model; Parnell et al, 2010). Although outcomes of stomach content and isotopic analyses need to be interpreted with caution and may not be directly comparable, the combination of their results is highly useful to better understand the trophic ecology of marine predators (Albo-Puigserver et al, 2015;López et al, 2016;Olson et al, 2010;Young et al, 2015;Zudaire et al, 2015) In the present study, we examined the feeding ecology of swordfish, little tunny and Atlantic bonito in the western Mediterranean Sea using a combined approach of stomach contents and stable isotopes (nitrogen and carbon isotopic values) in muscle tissue. We then compared their trophic niche and trophic level with published trophic information of other sympatric pelagic predators present in the ecosystem.…”

Records of crustacean decapodid stages from the family Enoplometopidae (Crustacea: Decapoda) in the pelagic environment of the western Indian Ocean

“…occur throughout the south-western Indian Ocean: from Seychelles to Mauritius, from Reunion Island to Madagascar and Mozambique Channel (Fig. 3) [See also Potier et al, 2004Potier et al, , 2007aPotier et al, , b, 2014Zudaire et al, 2015]. Reunion Island and La Pérouse seamount, situated ~90 miles north-west of Reunion, are major hotspots of these occurrences.…”
