We tested the hypothesis that cardiorespiratory differences known to exist among adult sockeye salmon populations also exist in the juveniles. To test this hypothesis, we compared cardiac contractility and adrenergic responsiveness of juvenile sockeye salmon from two geographically isolated populations that were reared from eggs under common garden conditions and at two acclimation temperatures (5 °C and 14 °C). However, we found no substantive differences in the force-frequency response (FFR… 


The Effect of Temperature Acclimation and Adrenaline on the Performance of a Perfused Trout Heart
Cardiac performance was examined with in situ perfused trout hearts at two acclimation temperatures, 5 C and 15 C. In series I, adrenaline-free perfusion and a cumulative dose response up to 1 μgmol
Effects of temperature and anoxia upon the performance of in situ perfused trout hearts
Increased functional impairment following anoxic exposure at elevated temperature occurred even though both cardiac glycolytic enzyme activity and the rate of lactate production were increased proportionally with cardiac work, as biochemical and energetic parameters were generally unaffected by anoxia.
In vitro cardiac performance in triploid brown trout at two acclimation temperatures
It was concluded that triploidy is not associated with a major deficiency in maximum cardiac performance, but a heightened sensitivity to ryanodine was discovered, which indicated an enhanced role for the sarcoplasmic reticulum in excitation-contraction coupling in these triploids fish.
Results suggest that cardiac tissue from rainbow trout acclimated to 8°C has a greater cell surface adrenoceptor population available for beta-antagonist binding, which might explain the heightened cardiac sensitivity to adrenaline observed in situ and in vitro in 6°C-acclimated fish.
Effect of Season and Temperature Acclimation on the Function of Crucian Carp (Carassius Carassius) Heart
The results show that acclimation to cold does not induce positive compensatory changes in function or size of crucian carp heart, as happens in many other teleost fishes, and an inverse or noncompensatory acclimations was found.
The temperature challenges on cardiac performance in winter-quiescent and migration-stage eels Anguilla anguilla.
The role of adrenergic stimulation in maintaining maximum cardiac performance in rainbow trout (Oncorhynchus mykiss) during hypoxia, hyperkalemia and acidosis at 10°C
The results suggest that adrenergic stimulation of the trout heart is critical in maintaining maximum performance during prolonged swimming tests, and probably during all forms of exhaustive activity and recovery, when venous blood is hyperkalemic, acidotic and hypoxic.
Intraspecific differences in endurance swim performance and cardiac size in sockeye salmon (Oncorhynchus nerka) parr tested at three temperatures
Populations significantly differed in endurance swim performance and these differences were related to the natal lake environment.
The effect of acute temperature increases on the cardiorespiratory performance of resting and swimming sockeye salmon (Oncorhynchus nerka)
High temperature fatigue of swimming sockeye salmon was not a result of a failure of either oxygen delivery to the gills or oxygen diffusion at the gill because oxygen partial pressure (PO2) and oxygen content (CO2) in arterial blood did not decrease with increasing temperature, as would be predicted for such limitations.
Optimum and maximum temperatures of sockeye salmon ( Oncorhynchus nerka ) populations hatched at different temperatures
Temperature tolerance and heart rates were compared among nine sockeye salmon (Oncorhynchus nerka (Walbaum in Artedi, 1792)) populations, whose eggs were incubated at 10, 14, and 16 °C before rearing
