... models, but lack the generality of DEB models. We review the interconnections between the two approaches and present formulae relating the state variables and fluxes in the standard DEB model to measured bioenergetic rate processes. We illustrate this synthesis for two large fishes: Pacific bluefin tuna...

...Nicholas C. Wegner; N. Chin Lai; Kristina B. Bull; Jeffrey B. Graham SUMMARY Ram ventilation and gill function in a lamnid shark, the shortfin mako, Isurus oxyrinchus , were studied to assess how gill structure may affect the lamnid–tuna convergence for high-performance swimming. Despite...

... in cardiomyocytes from Pacific bonito ( Sarda chiliensis ), Pacific mackerel ( Scomber japonicus ), yellowfin tuna ( Thunnus albacares ) and Pacific bluefin tuna ( Thunnus orientalis ). The whole-cell voltage-clamp technique was used to measure the temperature sensitivity of the L-type Ca 2+ channel current ( I Ca...

...Jess Boye; Michael Musyl; Richard Brill; Hans Malte SUMMARY We developed a 2D heat flux model to elucidate routes and rates of heat transfer within bigeye tuna Thunnus obesus Lowe 1839 in both steady-state and time-dependent settings. In modeling the former situation, we adjusted the efficiencies...

...Q. P. Fitzgibbon; R. S. Seymour; D. Ellis; J. Buchanan SUMMARY The effect of feeding on the rate of oxygen consumption( Ṁ O 2 ) of four groups of three southern bluefin tuna Thunnus maccoyii (SBT) was examined in a large static respirometer at water temperatures of 18.2-20.3°C. Six feeding events...

... the functional pressure range, arteries from blue marlin ( Makaira nigricans ) and yellowfin tuna ( Thunnus albacares ) have J-shaped pressure-volume (P-V) loops, while bulbi from the same species have r-shaped P-V loops, with a steep initial rise followed by a compliant plateau phase. The steep initial rise...

... adjustments are made for differences in temperature,bonito net swimming costs are similar to those of similar-sized yellowfin tuna Thunnus albacares (tribe Thunnini), but the bonito has a significantly lower SMR. Because bonitos are the sister group to tunas, this finding suggests that the elevated SMR...

However, the red muscle temperatures measured in swimming makos (0.3–3°C above T a ) are cooler than those measured previously...
