2017, Fish PhysiologyCitation Excerpt :At physiological temperatures, the rate of SR Ca2 + uptake is significantly lower in fish cardiac tissue homogenates than in those of mammals (Aho and Vornanen, 1998). However, active fishes such as bluefin tuna (Thunnus thynnus) with elevated cardiac function have a more developed SR and rely much more on SR Ca2 + cycling, and therefore, SERCA activity than other less active species (Farrell, 1996). β-Adrenergic stimulation in fishes increases peak intracellular [Ca2 +], myocardial twitch force, and augments cardiac energy consumption of the contractile system.

2015, Fish PhysiologyCitation Excerpt :To the best of our knowledge, this has never been investigated in elasmobranchs and it is possible that the concern may be irrelevant because of the dermal denticles and thickened and nonvascular skin of elasmobranchs limit cutaneous gas exchange. It's long been recognized that the functional properties of the cardiovascular system in teleosts (i.e., those shown in Eq. 1.1 that determine rates of oxygen delivery to the tissues) are necessarily correlated with species’ energetics (i.e., routine and maximum aerobic metabolic rates) (e.g., Brill, 1996; Brill and Bushnell, 1991, 2001; Farrell, 1991, 1996; Bernal et al., 2012). Although, as extensively discussed by Coulson (1977, 1986, 1997), in evolutionary terms the specific cause-and-effect relationships between cardiovascular function and metabolic rate are complex.
