Summary The diet of juvenile bluefin tuna (Thunnus thynnus) caught 2 to 8 miles off NE Sicily was investigated in order to improve knowledge of the species’ early life history. From 1998 to 2000, 107 specimens ranging from 63 to 495 mm (total length) were fished between July and November. Fishes were caught by trolling line or purse seine in a Fish Aggregating Devices (FADs) area 2 to 8 miles offshore and as by-catch of the purse-seine sardine fishery 2 to 4 miles offshore. Most frequently… 
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)
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.
Feeding habits of the Atlantic bluefin tuna, Thunnus thynnus (L. 1758), in the central Mediterranean Sea (Strait of Messina)
The predation on the high-energetic food as mesopelagic and bathypelagic fishes during the pre-spawning and the spawning period may bring an energetic advantage in tuna metabolism and gonadal maturation.
Diet composition of bluefin tuna (Thunnus thynnus L. 1758) in the Eastern Mediterranean Sea, Turkey
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.
Dietary Evidence of Mesopelagic and Pelagic Foraging by Atlantic Bluefin Tuna (Thunnus thynnus L.) during Autumn Migrations to the Iceland Basin
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.
Open-ocean foraging ecology of southern bluefin tuna Thunnus maccoyii based on stomach contents
The foraging ecology of southern bluefin tuna Thunnus maccoyii in open-ocean habitats of temperate waters in the southern hemisphere is investigated by analyzing their stomach contents, providing basic informa- tion that will improve the understanding of the oceanic food webs in southern temperates waters.
Ontogenetic diet shift of age-0 year Pacific bluefin tuna Thunnus orientalis.
The observed data suggest that T. orientalis switch to a diet more based on fish prey items, which have more body mass and greater swimming ability than small squid and zooplankton, after they reach a L(F) of 25 cm.
Feeding habits and trophic levels of bluefin tuna Thunnus thynnus of different size classes in the Mediterranean Sea
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.
Diet of young Atlantic bluefin tuna (Thunnus thynnus) in eastern and western Atlantic foraging grounds
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.
Feeding ecology of little tunny Euthynnus alletteratus in the central Mediterranean Sea
Comparative analysis performed on prey abundance highlighted a trend of increasing predator size-classes among prey items, and Maurolicus muelleri was the most important prey for the largest specimens analysed.
A Global Review on the Biology of the Dolphinfish (Coryphaena hippurus) and Its Fishery in the Mediterranean Sea: Advances in the Last Two Decades
The results suggest, among other effects, some temporal synchronicity in landings across countries, potential interannual stock movement affecting inter-country catches, diverging trends in prices and insufficient quality in the estimates of fishing effort.


Feeding habits of skipjack tuna Katsuwonus pelamis and other tuna Thunnus spp. juveniles in the tropical western Pacific
The results indicate that the skipjack juvenile is primarily a piscivorous feeder although they also depend on various other prey organisms, whereas the other tuna juveniles are stronger piscvorous feeders.
