during winter in Australia, and migrate to tropical areas in the north-western Indian Ocean, from spring to autumn, for the spawning season. Their preferred temperature range is 18–20 °C (64–68 °F), with most of their time (91%) spent below 21 °C (70 °F). Southern bluefin tunas experience a wide range of ambient water temperatures, from a minimum of 2.6 °C (36.7 °F) to a maximum of 30.4 °C (86.7 °F). All species of tuna are reported to spawn in water temperatures above 24 °C (75 °F). However, 24 °C (75 °F) is outside, or at the upper limit, of temperature tolerances for bluefin tunas. Large individuals have been found to withstand temperatures of less than 10 °C (50 °F) and as low as 7 °C (45 °F) for over 10 hours, possibly to search for prey. During the day they migrate through depths between 150–600 m (490–1,970 ft), but at night they stay in waters that are 50 m (160 ft) or less in depth.
721:. This low surface-area-to-volume ratio explains why there is a more significant amount of heat lost at the site of the gills compared to the body surface. As a result, the rete vascular system is located mostly at the site of the gills, but also at several other organs in the tuna. Specifically, due to the high metabolic demand of the southern bluefin tuna, the stomach is an organ requiring a high demand of thermoregulation. It is only able to digest food at specific temperatures, often much higher than the temperature of the surrounding water. Since the food is ingested along with a large amount of seawater, the contents must be heated to a temperature that allows the food to be digested and the nutrients and ions taken up. The southern bluefin tuna seems to increase blood flow to the stomach at times of increased digestion, by increasing the diameter of blood vessels flowing to the stomach, allowing more warm blood to reach the organ at a quicker rate. 761: 752:
conserve heat when they return into the depths. Through this unique ability, tunas can reach out into otherwise hazardously cold water in order to hunt for food or escape from predators. Variations in their muscle temperatures are not necessarily influenced by water temperatures or that of swimming speeds, which indicates the ability of the bluefin tuna to control the level of efficiency of their heat exchange system. Relating to the efficiency of oxygen extraction, tuna gill structure maximizes contact between water and the respiratory epithelium, which minimizes anatomical and physiological “dead space” in order to enable more than 50% oxygen-extraction efficiencies. This allows the fish to maintain a high rate of oxygen consumption as it continually swims out to others areas of oceans in search of food and ground for growth and reproduction.
1617:), along with a live-feed production plant. This facility has more recently been upgraded to a $ 6.5 million special purpose SBT larval rearing recirculation facility. During the most recent summer (2009/2010), the company completed its third consecutive annual on-shore southern bluefin tuna spawning program, having doubled the controlled spawning period to three months at its Arno Bay facility. Fingerlings are now up to 40 days old with the grow-out program, and the spawning period has been extended from 6 weeks to 12, but as yet, grow-out of commercial quantities of SBT fingerlings has been unsuccessful. Whilst aquaculture pioneers Clean Seas Limited have not been able to grow out commercial quantities of SBT fingerlings from this season's trials, the SBT broodstock were wintered and conditioned for the 2010-11 summer production run. 1523:) and the use of formulated pellets is not yet viable. This cost is largely due to the expense of dietary research. The annual costs of diet for research alone is approximately US$ 100,000 and there are additional problems associated with working with large, fast-swimming marine animals. Farm-raised tuna generally have a higher fat content than wild tuna. A one-metre tuna needs about 15 kg (33 lb) of live fish to gain 1 kg (2 lb) of fat, and about 1.5 to 2 tonnes of squid and mackerel are needed to produce a 100 kg (220 lb) bluefin tuna. Research evaluating ingredients for use in southern bluefin tuna feed is ongoing, and gathering information on ingredient digestibility, palatability and nutrient utilisation and interference can improve lower costs for tuna ranchers. 5366: 1794: 614:. They are endotherms, which means that they can maintain their internal temperature elevated above water temperature. Heat is lost through heat transfer throughout the whole body surface and the gills, so prevention of metabolic heat loss is important. This is an adaptive feature, because it is far more difficult for an organism to maintain a temperature differential with its environment in water than in air. It allows tunas to have faster metabolic reactions, to be more active, and to exploit colder environments. A disadvantage is that they require a high energy input and insulation, and there is potential for greater heat loss, because of the high temperature gradient with the environment. To reduce heat loss, southern bluefin tunas have reduced their 351:, the rate of the gas diffusion across the gas exchange membrane is directly proportional to the respiratory surface area, and inversely proportional to the thickness of the membrane. Tunas have highly specialized gills, with a surface area 7–9 times larger than that of other aquatic environment organisms. This increased surface area allows more oxygen to be in contact with the respiratory surface and therefore diffusion to take place more quickly (as represented by the direct proportionality in the Fick equation). This massive increase in surface area of the gills of the southern bluefin tuna is due to a higher density of secondary lamella in the gill filaments. 355:
get to the blood. Similarly to the increased surface area, this allows the highly metabolic organism to take oxygenated blood into the circulatory system more quickly. On top of a quicker rate of diffusion in the respiratory system of southern bluefin tuna, there is a significant difference in the efficiency of the oxygen uptake. While other teleost fish typically utilize 27–50% of the oxygen in the water, the tuna's utilization rates have been observed as high as 50-60%. This overall high oxygen uptake works in close coordination with a well-adapted circulatory system to meet the high metabolic needs of the southern bluefin tuna.
432:
oxygen diffusion. The circulatory system works together with the respiratory system to rapidly transport oxygen to tissues. Due to high hemoglobin levels, the blood of southern bluefin tuna has a high oxygen carrying capacity. Furthermore, their large hearts, with a characteristic organization of muscle fibres, allow for comparatively high cardiac outputs, as well as rapid ejection of stroke volume. This, together with the organization of blood vessels and a countercurrent heat exchange system, allows the southern bluefin tuna to rapidly deliver oxygen to tissue, while preserving energy necessary for their active lifestyle.
340:
does not require a separate pump mechanism to pump water over the gills. Ram ventilation is said to be obligatory in southern bluefin tunas, because the buccal-opercular pump system used by other teleost fish became incapable of producing a stream of ventilation vigorous enough for their needs. All species of tuna in general have lost the opercular pump, requiring a quicker movement of oxygenated water over the gills than induced by the suction of the opercular pump. Therefore, if they stop swimming, tunas suffocate due to a lack of water flow over the gills.

its entire range. Improved refrigeration techniques and a demanding global market saw global SBT catch plummet from 80,000 tonnes a year during the 1960s to 40,000 tonnes a year by 1980. Australian catch peaked in 1982 at 21,500 tonnes, and the total population of SBT has since declined by about 92 percent. There was a pressing obligation to reduce harvesting pressure southern bluefin tuna populations in the mid-1980s. The main nations fishing the species adapted their practise to manage their catches, although no official quotas were put in place.
1856: 709:. Instead, the southern bluefin tuna seems to implement a system that regulates how actively the rete mirable system heats the tissues. Experiments involving the southern bluefin tuna have led researchers to believe that this species of tuna has developed a shunting system. When the southern bluefin tuna experiences cold temperatures, more blood is directed to the rete vascular system, heating muscle tissue, while in warm temperatures, blood is shunted to the venous and arterial systems, reducing the heat in the muscle tissues. 969: 1481:. However, as yet the manufactured feeds are not competitive with the baitfish. A further future prospect in enhancing the ranching of SBT is the plan of Long Term Holding. By holding its fish for two successive growing seasons (18 months) instead of one (up to 8 months), the industry could potentially achieve a major increase in volume, greater production from the limited quota of wild-caught juveniles, and ability to serve the market year round. This presents several uncertainties, and is still in the planning stage. 1377: 1763:
largest nutrient polluter (734 tonnes per annum) but is distributed across a larger area which includes Port Lincoln, Arno Bay, Port Neill and Fitzgerald Bay (near Whyalla). These combined nutrient inputs are ecologically significant, as Spencer Gulf is an inverse estuary and a naturally low-nutrient environment. Wastewater treatment plants from the region's largest settlements at Port Augusta, Port Lincoln, Port Pirie and Whyalla contribute a combined total of 54 tonnes of nitrogenous nutrient to Spencer Gulf.
1348: 1288: 532:, i.e. urine solute to plasma solute ratio is close to 1 (U/P≅1). Because of this, solely excreting urine is not sufficient to resolve the osmoregulatory problem in tunas. In turn, they excrete only the minimum volume of urine necessary to rid of solutes that are not excreted by other routes, and the salt is mostly excreted via gills. This is why the composition of solutes in urine differs significantly from that of the blood plasma. Urine has a high concentration of divalent ions, such as Mg and SO 1159: 75: 1657: 1083: 1007: 931: 6442: 1045: 50: 1460:, between the north-west Coast of Australia and Indonesia. The eggs are estimated to hatch within two to three days, and over the next two years attain sizes of approximately 15 kilograms. The principal wild catch of the Australian SBT industry is fish aged two to three years. It is believed that SBT become sexually mature between 9 and 12 years in the wild, which highlights the major negative impact of removing pre-spawning populations from the wild. 1407: 6435: 1779: 1121: 701:). Due to their anatomical positioning, the heart and the liver are the coldest organs and significant work needs to be expended for them to serve a regionally warmer body. It is likely that the reversed temperature effect on oxygen binding was developed to ensure adequate unloading of oxygen at the heart and liver, especially in colder waters when the difference in temperature between these organs and the swimming muscle is the greatest. 31: 799:

Clean Seas has attempted to address this by focusing research effort on closing the life-cycle of the species with the potential benefit of alleviating some of the fishing pressure on declining stocks, but has not succeeded.
536:(U/P>>1), as these ions are mostly excreted by the kidneys keeping their concentration in blood plasma from rising. Monovalent ions (Na, Cl, K) are excreted by the gills, so their U/P ratios in the urine are below 1.
