Amino-Acid Composition of Hæmoglobin from Thunnus thynnus
Nature, 1958WE have recently crystallized1 haemoglobin and myoglobin of the saltwater fish, Palamys sarda and Thunnus thynnus. Some physico-chemical and functional properties of these pigments have been described2–4. In this communication we report the amino-acid composition of Thunnus thynnus haemoglobin, as determined by chromatography on an ion-exchange resin ...

Farming Thunnus thynnus in Mediterranean Sea: Is an Illusion?
Poultry, Fisheries & Wildlife Sciences, 2015Thunnus thynnus is one of the most popular species in the world. Tuna fishing is an economic activity of prime importance and a booming business. The reproduction control in captivity represents the first step for the production of Tuna in captivity. Tuna, thanks to its palatability, would be an excellent candidate for aquaculture, but unfortunately ...

Microcalorimetric measurement of the specific heat of Thynnus Thunnus
Thermochimica Acta, 1989Abstract The specific heat of Thynnus Thunnus from 295 to 413 K was measured using sealed samples of ca. 10 mg in a Calvet high temperature microcalorimeter. A drop method was used, the equipment being calibrated using the specific heat of copper, which gave values from 3.16±0.03 J K −1 g −1 at 295 K to 3.75 ± 0.05 J K −1 g −1 at 413 K.

Effects of age on growth in Atlantic bluefin tuna (Thunnus thynnus)
General and Comparative Endocrinology, 2018Atlantic Bluefin Tuna Thunnus thynnus (ABFT) is considered one of the most important socio-economic species but there is a lack of information on the physiological and molecular processes regulating its growth and metabolism. In the present study, we focused on key molecules involved in growth process.

Oxidation of lactate in the compact and spongy myocardium of tuna fish (Thunnus thynnus thynnus L.)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1980Abstract 1. 1. In comparison with the compact, the spongy compartment shows higher accumulation of lactate and higher capacity both to carry out different stages of lactate oxidation and to incorporate lactate into the total cardiac lipids. In addition, lactate oxidation in the spongy is less depressed by acidosis. 2. 2.

Molecular Ecology Notes, 2004
AbstractTwenty‐five microsatellites from Atlantic bluefin tuna (Thunnus thynnus thynnus) were characterized. All 25 microsatellites were polymorphic; the number of alleles among up to 56 individuals surveyed ranged from two to 23. Atlantic bluefin tuna are highly exploited and major questions remain as to stock structure and abundance in the eastern ...

Microparasites of reared bluefin tuna (Thunnus thynnus)
Parassitologia, 2007Prasitofauna of blufin tuna is composed of high number of species that in optimal farming conditions it shows no tendency for intensive proliferation, and thus does not represent a real health threat. It is noteworthy that highly pathogenic parasites implicated in mortalities of southern bluefin tuna (T.

Lipoma in a farmed northern bluefin tuna, Thunnus thynnus (L.)
Journal of Fish Diseases, 2006An adult male northern bluefin tuna from an ongrowing site was sent to the laboratory for histopathological examination. The mass was located in the dorsal musculature over the vertebral column. It was oval shaped, firm in consistence and measured 35 X 22 cm. The tumour appeared well delimited by the surrounding tissues.

Cardiac growth, myoglobin, proteins and DNA in developing tuna (Thunnus thynnus thynnus L.)
Comparative Biochemistry and Physiology Part A: Physiology, 1981Abstract 1. 1. The relative heart weight in the developing tuna (body weights range from 0.6–350 kg) is substantially greater than in other seawater fish and corresponds to values found in small mammals. 2. 2. The relative heart weight shows two different growth velocities with the breaking point between 10 and 20 kg of body weight.

The structure of the pineal organ of the bluefin tuna, Thunnus thynnus
Journal of Morphology, 1971AbstractThe pineal organ of the bluefin tuna was studied using light and electron microscopy. The pineal, an evagination in the diencephalic pallium, consists of a distal expanded end‐organ and a stalk. A pineal nerve connects this end‐organ to the habenular area of the diencephalon.
