“…The maximum swimming rate of goldfish, acclimated to 15°C water temperatures, declined at 20°C (Fry and Hart, 1948;Johnston and Temple, 2002). Furthermore, T max of goldfish acclimated to 12°C water was 27°C (Ferreira et al, 2014), which is the same temperature that goldfish acclimated to 10°C lost their ability to escape predators (Johnston and Temple, 2002).…”

“…The apparent link between cardio-respiratory transition temperatures and performance has been further illustrated in the eurythermic goldfish (Carassius auratus). A T opt of 20°C was calculated for goldfish acclimated to 12°C water temperature (Ferreira et al, 2014). The maximum swimming rate of goldfish, acclimated to 15°C water temperatures, declined at 20°C (Fry and Hart, 1948;Johnston and Temple, 2002).…”

“…We also hypothesized that breathing rates in 1°C acclimated fish would always return to resting after being chased faster than 6.5°C acclimated fish, which in fact turned out to be the opposite. We did, however, anticipate that the suite of physiological rate transition temperatures would show a predictable order, as seen previously in goldfish (Ferreira et al, 2014;Farrell, 2016 (Drost et al, 2014). In brief, B. saida were held at 0°C for up to 4 weeks at Cambridge Bay to ensure good health before being transported by air at 0°C to the Vancouver Aquarium, British Columbia, Canada.…”

“…Both the aerobic scope (e.g. Brett, 1962;Ultsch et al, 1980;McKenzie et al, 2012;Eliason et al, 2013a;Killen et al, 2014;Del Raye and Weng, 2015) and ƒ H (Stillman, 2002;Blank et al, 2004;Braby and Somero, 2006;Franklin et al, 2007;Sidhu et al, 2014;Chen et al, 2013;Verhille et al, 2013;Anttila et al, 2014;Ferreira et al, 2014) measurements have been reinstituted to investigate the thermal niches of fishes in this era of rapid climate change. We tested the hypothesis that the cardio-respiratory system of B. saida would thermally acclimate at 0.5, 3.5 and 6.5°C.…”

As a consequence of the growing concern about warming of the Arctic Ocean, this study quantified the thermal acclimation responses of Boreogadus saida, a key Arctic food web fish. Physiological rates for cardio-respiratory functions as well as critical maximum temperature (T c,max ) for loss of equilibrium (LOE) were measured. The transition temperatures for these events (LOE, the rate of oxygen uptake and maximum heart rate) during acute warming were used to gauge phenotypic plasticity after thermal acclimation from 0.5°C up to 6.5°C for 1 month (respiratory and T c,max measurements) and 6 months (cardiac measurements). T c,max increased significantly by 2.3°C from 14.9°C to 17.1°C with thermal acclimation, while the optimum temperature for absolute aerobic scope increased by 4.5°C over the same range of thermal acclimation. Warm acclimation reset the maximum heart rate to a statistically lower rate, but the first Arrhenius breakpoint temperature during acute warming was unchanged. The hierarchy of transition temperatures was quantified at three acclimation temperatures and was fitted inside a Fry temperature tolerance polygon to better define ecologically relevant thermal limits to performance of B. saida. We conclude that B. saida can acclimate to 6.5°C water temperatures in the laboratory. However, at this acclimation temperature 50% of the fish were unable to recover from maximum swimming at the 8.5°C test temperature and their cardio-respiratory performance started to decline at water temperatures greater than 5.4°C. Such costs in performance may limit the ecological significance of B. saida acclimation potential.

Atlantic salmon show capability for cardiac acclimation to warm temperatures

et al. 2014

Increases in environmental temperature predicted to result from global warming have direct effects on performance of ectotherms. Moreover, cardiac function has been observed to limit the tolerance to high temperatures. Here we show that two wild populations of Atlantic salmon originating from northern and southern extremes of its European distribution have strikingly similar cardiac responses to acute warming when acclimated to common temperatures, despite different local environments. Although cardiac collapse starts at 21-23°C with a maximum heart rate of B150 beats per min (bpm) for 12°C-acclimated fish, acclimation to 20°C considerably raises this temperature (27.5°C) and maximum heart rate (B200 bpm). Only minor population differences exist and these are consistent with the warmer habitat of the southern population. We demonstrate that the considerable cardiac plasticity discovered for Atlantic salmon is largely independent of natural habitat, and we propose that observed cardiac plasticity may aid salmon to cope with global warming.
