The study of feeding habits of the Atlantic bluefin tuna was carried out in 123 specimens, ranging from 115 to 222 cm fork length (FL) and collected during spring seasons of 2010 and 2011 in the central Mediterranean Sea (Strait of Messina). The analysis of stomach contents allowed us to identify 91 taxa of prey items, mainly belonging to Teleostea (54), Cephalopoda (20) and Crustacea (13). The percentage of index of relative abundance (IRI) shows the highest values for the myctophid Hygophum… Expand

Cephalopods in the diet of young-of-the-year bluefin tuna (Thunnus thynnus L. 1758, Pisces: Scombridae) from the southern Tyrrhenian Sea (central Mediterranean Sea)
TLDR
In general, young-of-the-year bluefin tunas are able to feed on a large spectrum of cephalopod prey in the study area, usually relying on juvenile specimens and epipelagic and mesopelagic shoaling species. Expand
Diet of the spothead lanternfish Diaphus metopoclampus (Cocco, 1829) (Pisces: Myctophidae) in the central Mediterranean Sea
TLDR
D. metopoclampus is a zooplanktivorous predator, consuming mainly Crustacea, but also Mollusca, Polychaeta, Chaetognatha, Taliacea and Actinopterygii, and showing a moderate opportunistic feeding strategy, and can be ascribed to the group of acyclic predators. Expand
Diet composition and feeding ecology of mackerel tuna Euthynnus affinis (Cantor, 1849) on the South-Eastern coast of India
TLDR
The diet composition of 244 specimens of mackerel tuna, Euthynnus affinis, ranging from 26 to 59 cm in total length collected on the southeast coast of India, showed large fishes fed primarily on teleosts, whereas medium sized fishes predominantly consumed crustacean and molluscan prey. Expand
Consumption of mesopelagic prey in the Strait of Messina, an upwelling area of the central Mediterranean Sea: feeding behaviour of the blue jack mackerel Trachurus picturatus (Bowdich, 1825)
Abstract This study describes for the first time the feeding behaviour and mesopelagic food consumption of adult Trachurus picturatus in the Strait of Messina (central Mediterranean Sea), where theExpand
Diet and trophic ecology of the lanternfish Electrona risso (Cocco 1829) in the Strait of Messina (central Mediterranean Sea) and potential resource utilization from the Deep Scattering Layer (DSL)
TLDR
The results indicate that E. risso is a specialist predator, which feeds mainly on the small mesopelagic fish Cyclothone braueri and in minor proportion on zooplankton, with a prevalence of copepods. Expand
Few But Relatively Large Prey: Trophic Ecology of Chauliodus sloani (Pisces: Stomiidae) in Deep Waters of the Central Mediterranean Sea
TLDR
The examination of food size spectrum, in relation to predator length, demonstrated that C. sloani developed a feeding strategy aimed to maximizing energy input and based on the capture of few and relatively large prey: more than 50% of prey items exceeded the value of 20% for ratio between prey and predator size (SL). Expand
Feeding ecology of Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Saint Lawrence, Canada.
TLDR
Feeding ecology of Atlantic bluefin tuna (ABFT), from the Gulf of Saint Lawrence, Canada, was assessed by stomach content and stable isotope analyses and PERMANOVA analysis revealed significant differences in the dietary composition between years. Expand
Dietary Evidence of Mesopelagic and Pelagic Foraging by Atlantic Bluefin Tuna (Thunnus thynnus L.) during Autumn Migrations to the Iceland Basin
TLDR
The dietary composition of ABFT during autumn migrations to the Iceland Basin south of the continental shelf of Iceland gives new baseline knowledge for future comparison with anticipated oceanographic-biological changes in the region in the coming decades and can be used to help parameterize new models of AB FT migration behavior and trophic role. Expand
Diet and consumption rate of Atlantic bluefin tuna (Thunnus thynnus) in the Strait of Gibraltar
TLDR
The trophic niche width, estimated from SCA as the antilogarithm of Shannon's entropy, as well as from stable isotope Bayesian ellipses, indicated that the ABFT sampled in 2012 consumed a more diverse diet than those sampled in 2013, which is probably due to differences in water temperatures between the sampling dates of the two years. Expand
Feeding ecology of blue whiting (Micromesistius poutassou) in the NW Mediterranean: The important role of Myctophidae
TLDR
The seasonal and spatial differences observed in the feeding ecology of the Mediterranean blue whiting are related to the energetic requirements of the species throughout the year and with changes in the spatial distribution of the different ontogenetic phases. Expand

Diet composition of bluefin tuna (Thunnus thynnus L. 1758) in the Eastern Mediterranean Sea, Turkey
TLDR
New information on the diet composition of T. thynnus in the eastern Mediterranean Sea is revealed and the findings indicate that, depending on the abundance of the different prey species in the habitat, the dominant prey species can be distinctive. Expand
Feeding habits of the albacore tuna Thunnus alalunga (Perciformes, Scombridae) from central Mediterranean Sea
TLDR
The results showed that the albacore tuna is a pelagic predator focusing on paralepidid fish and, more in detail, on two species such as Paralepis speciosa and Paraleps coregonoides, and can be considered as a top carnivore. Expand
Diet of young‐of‐the‐year bluefin tuna, Thunnus thynnus (Linnaeus, 1758), in the southern Tyrrhenian (Mediterranean) Sea
TLDR
It is suggested that young-of-the-year tuna have an essentially piscivorous diet, although invertebrate prey provide a substantial contribution to the food array. Expand
Differences in diet of Atlantic bluefin tuna (Thunnus thynnus) at five seasonal feeding grounds on the New England continental shelf
TLDR
This is the first study to compare diet composition of western Atlantic bluefin tuna among discrete feeding grounds during their seasonal migration to the New England continental shelf and to evaluate predator-prey size relationships. Expand
Diet of young Atlantic bluefin tuna (Thunnus thynnus) in eastern and western Atlantic foraging grounds
TLDR
The findings indicate that juvenile bluefin tuna targeted a relatively small range of prey species and regional foraging patterns remained consistent over time in the Mid-Atlantic Bight but changed in relation to local prey availability in the Bay of Biscay. Expand
Food and feeding ecology of juvenile albacore, Thunnus alalunga, off the Bay of Biscay: a case study
TLDR
The diet of 78 albacore caught in the French driftnet fishery during summer 1993 is analysed and fish dominated the diet, with the most important being Maurolicus muelleri, Scomberesox saurus, and Arctozenus risso. Expand
Pelagic cephalopods of the central Mediterranean Sea determined by the analysis of the stomach content of large fish predators
TLDR
The presence of cephalopod beaks in the stomach of predators represents a fundamental tool to assess the biodiversity and the ecological importance of these taxa in the marine ecosystem. Expand
Feeding habits and trophic levels of bluefin tuna Thunnus thynnus of different size classes in the Mediterranean Sea
TLDR
Bluefin tuna, from small juveniles to giants, showed a shift in feeding preferences due to different use of habitats and food items as a function of the life stage. Expand
Feeding Partitioning among Tuna Taken in Surface and Mid-water Layers: The Case of Yellowfin ( Thunnus albacares ) and Bigeye ( T. obesus ) in the Western Tropical Indian Ocean
TLDR
The trophic relations of two apex predators, yellowfin and bigeye tuna (Thunnus albacares and T. obesus), and their prey were investigated in the western tropical Indian Ocean to reflect their ability to catch the prey, and their vertical distribution. Expand
