To obtain the desired brown or black crust, the meat surface must exceed 150 °C (300 °F) [1], so searing requires the meat surface be free of water, which boils at around 100 °C (212 °F). Although often said to "lock in the moisture" or "seal in the juices", in fact, searing results in a greater loss of moisture than cooking to the same ...
A study using sonar in French Polynesia, found large shoals of juvenile bigeye tuna and yellowfin tuna aggregated closest to the devices, at distances of 10 to 50m. Further out, 50 to 150m, a less dense group of larger yellowfin and albacore tuna gathered. Yet further out, to 500m, was a dispersed group of mature tuna.
The water activity, a w, in a fish is defined as the ratio of the water vapour pressure in the flesh of the fish to the vapour pressure of pure water at the same temperature and pressure. It ranges between 0 and 1, and is a parameter that measures how available the water is in the flesh of the fish.
A tuna (pl.: tunas or tuna) is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae family.The Thunnini comprise 15 species across five genera, [2] the sizes of which vary greatly, ranging from the bullet tuna (max length: 50 cm or 1.6 ft, weight: 1.8 kg or 4 lb) up to the Atlantic bluefin tuna (max length: 4.6 m or 15 ft, weight: 684 kg or 1,508 lb), which ...
It may sound counterintuitive, but drinking more water can help you lose water weight. "For most people, drinking more water will actually flush out the sodium," says Badgett. Drinking enough ...
The gills are composed of comb-like filaments, the gill lamellae, which help increase their surface area for oxygen exchange. [10] When a fish breathes, it draws in a mouthful of water at regular intervals. Then it draws the sides of its throat together, forcing the water through the gill openings, so that it passes over the gills to the outside.
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%.
At maturity it is about 1.5 m (4 ft 11 in) long and weighs about 60 kg (130 lb). [3] Individuals that are 2 m (6 ft 7 in) long are regularly seen, and the maximum reported is 3 m (9.8 ft) in length and 450 kg (990 lb) in weight. [6] Elsewhere, a mass of up to 550 kg (1,210 lb) has been reported for the species. [14]
