Conséquences de l’acclimatation à différents régimes thermiques sur les taux métaboliques standards des tacons du saumon de l’Atlantique(Salmo salar)

摘要: Fish that inhabits river are subjected to circadian fluctuations in water temperature. These can influence growth, digestion and metabolic processes. Bioenergetic models traditionally modeled using data recorded from fish kept at constant temperatures. could underestimate the energy spent by fluctuating Thus, with intermittent-flow respirometry, objectives of this study were to: (1) quantify differences between standard rates acclimatized a temperature (20.2 o C ± 0.5 C) two temperatures (19.8 2.0 C; 19.5 3.0 (2) compare methodology for calculate temperatures: respirometry (a) or (b) held have higher than At 20.2 C, was 25% 32% lower under fluctuations. However, results different strategies used did not differ.
