The yellowfin tuna (Thunnus albacares) is a species of tuna found in pelagic waters of tropical and subtropical oceans yellowfin tuna is among the larger tuna species, reaching weights over kg ( lb), but is significantly smaller than the Atlantic and Pacific bluefin tunas, which can reach over kg ( lb), and slightly smaller than the bigeye tuna and the . The EU purse seine fleet catches of yellowfin tuna (Thunnus albacares) from the Indian Ocean were standardized using the framework described in .
Abstract. Eight yellowfin tuna (Thunnus albacares, 48–99 cm FL) and three bigeye tuna (T. obesus, 56–64 cm FL) were tagged with coded ultrasonic transmitters inserted into the abdominal cavity of the released the tuna at two huge FADs (Nirai-1 and Nirai-8) off the south of Okinawa Island, Japan between 18 August and 15 October tuna caught around the world each year. In the UK, we consume aro tonnes (t) of tuna product each year. The key tuna species with annual catches are: skipjack tuna (Katsuwonus pelamis), million tonnes; yellowfin tuna (Thunnus albacares), million tonnes; bigeye tuna (Thunnus obesus), million tonnes; albacore.

The genus Thunnus encompasses eight economically important large tuna species, with the yellowfin tuna (Thunnus albacares, Bonnaterre ) representing the main source of fishery catch in this group, exceeding million tons in (Collette and Nauen ; ISSF ).
The Yellowfin Tuna is a delicious, hard-fighting fish that is sometimes caught when fishing deep waters off the Florida Keys. Yellowfin Tuna (Thunnus albacares) (Florida Record lbs.) The Yellowfin Tuna is one of the larger Tuna species and often reaches weights in.
Qiu, F. & Miyamoto, M. Use of nuclear DNA data to estimate genetic diversity and population size in Pacific Bluefin and Yellowfin Tuna (Thunnus orientalis and T.
albacares). CopeiaThe use of FADs is wide-spread throughout the world’s tropical oceans and is critical to the success of many tuna fisheries (Marsac et al., ; Sharp, b).These devices are believed to enhance the success of small-scale local pelagic fisheries by reducing search time and holding pelagic species, such as yellowfin tuna (Thunnus albacares) within the ranges of small.
Yellowfin tuna are caught on longlines that also catch endangered wildlife, such as turtles, seabirds, whales and dolphins. Reports of interactions with turtles, seabirds, whales and dolphins has increased significantly in recent years, most likely as a result of the introduction of video monitoring in the fishery.
Yellowfin tuna stocks are not classified as overfished. Video monitoring of all fishing boats operating in the tuna fishery is a welcome advance, improving confidence in fishery log book reports. Yellowfin tuna are caught on longlines that also catch endangered wildlife, such as turtles, seabirds, whales and dolphins.

Yellowfin tuna (Thunnus albacares) and spotted dolphins (Stenella attenuata) often swim together in the eastern tropical Pacific (ETP).
This fact has intrigued scientists for decades. A simple synopsis of current thinking about this issue is detailed below (with figures). In Hawaiian waters fishermen use the association between pantropical spotted dolphins (Stenella attenuata) and yellowfin tuna (Thunnus albacares) to catch tuna.
Targeting fishing effort around or in spotted dolphin groups has the potential to lead to bycatch, and anecdotal reports of hooking dolphins exist. We recorded information on fishing vessels associated with spotted.

The. The Yellowfin Tuna may also venture inshore of the continental shelf when the water temperature and clarity are suitable and the food is available in abundance. The Yellowfin Tuna is known to grow up really fast, up to pounds and have a shorter life span, of about 7 years, in comparison.
Most Yellowfin are able to reproduce at the age of 2. Freely moving fish, including yellowfin tuna (Thunnus albacares), rainbow trout (Oncorhynchus mykiss), zebrafish (Danio rerio), sharks, and short-tailed stingrays (Dasyatis brevicaudata), have been trained to discriminate the presence and absence of a magnetic intensity anomaly in experimental ses produced by the fish in different experiments included.
Fishing with vertical handlines at depths ranging from m to m yielded 90% yellowfin tuna (Thunnus albacares) and 10% skipjack tuna (Katsuwonus pelamis).
The yellowfin ranged in size from 1 kg to 60 kg. There is a possibility that some small bigeye tuna (Thunnus obesus) were caught, but were misidentified as yellowfin tuna. Purse seine.Oviparous batch spawner, with an inter-spawning interval of days in the Mediterranean Sea (Ref.
