“…Similar to previous findings (de Vlaming, 1971;Logan and Somero, 2010), warm acclimation increased upper thermal limits by more than 5°C, with 26°C-acclimated fish having a CT max of 38.9°C and 9°C-acclimated fish a CT max of 33.9°C (Table1). However, the highest CT max value recorded in this study was 0.8°C lower than that reported previously for this species (Logan and Somero, 2010).…”

SUMMARYAn insufficient supply of oxygen under thermal stress is thought to define thermal optima and tolerance limits in teleost fish. When under thermal stress, cardiac function plays a crucial role in sustaining adequate oxygen supply for respiring tissues. Thus, adaptive phenotypic plasticity of cardiac performance may be critical for modifying thermal limits during temperature acclimation. Here we investigated effects of temperature acclimation on oxygen consumption, cardiac function and blood oxygen carrying capacity of a eurythermal goby fish, Gillichthys mirabilis, acclimated to 9, 19 and 26°C for 4weeks. Acclimation did not alter resting metabolic rates or heart rates; no compensation of rates was observed at acclimation temperatures. However, under an acute heat ramp, warm-acclimated fish exhibited greater heat tolerance (CT max =33.3, 37.1 and 38.9°C for 9°C-, 19°C-and 26°C-acclimated fish, respectively) and higher cardiac arrhythmia temperatures compared with 9°C-acclimated fish. Heart rates measured under an acute heat stress every week during 28days of acclimation suggested that both maximum heart rates and temperature at onset of maximum heart rates changed over time with acclimation. Hemoglobin levels increased with acclimation temperature, from 35gl −1 in 9°C-acclimated fish to 60-80gl −1 in 19°C-and 26°C-acclimated fish. Oxygen consumption rates during recovery from acute heat stress showed post-stress elevation in 26°C-acclimated fish. These data, coupled with elevated resting metabolic rates and heart rates at warm temperatures, suggest a high energetic cost associated with warm acclimation in G. mirabilis. Furthermore, acclimatory capacity appears to be optimized at 19°C, a temperature shown by behavioral studies to be close to the speciesʼ preferred temperature.

“…The low precision and very wide temperature range used by the fish most of the year express the tolerance of the sand goby to temperature variation. This was also demonstrated by de Vlaming (1971) for Gillichthys mirabilis, and this is a consequence of these species being littoral, living and breeding in very shallow waters. As such, they will be exposed to great temperature fluctuations both seasonally and during the day.…”

“…The temperature preference also changed with the acclimation temperature. De Vlaming (1971), studying the goby Gillichthys mirabilis, showed that temperature preference neither varied significantly with season nor with varying acclimation temperature. R$ed (1979) found the same for the three spine stickleback Gasterosteus aculeatus in the Oslofjord.…”

SynopsisThe sand goby from the Oslofjord, Norway, is extremely eurythermal. In spring and autumn it avoids temperatures lower than about 4" C, in summer 6" C. Acclimation did not influence the lower avoidance temperature, but the critical thermal maximum, the upper avoidance temperature and the temperature where the whole fish darkened (the darkening temperature) varied with acclimation and season. The darkening temperature is suggested to be the upper temperature limit with the greatest ecological significance. The fish, collected at different seasons darkened at between 19.5 and 22" C. In the field the fish is not found at 20" C and higher.The preference temperature varied with season and with acclimation temperature, generally with low precision. In May, the preference temperature was 13.5" C, that is higher than the ambient temperature of 10" C. In summer, the temperature in sampling locality and preference temperature was the same, 17 and 16.5" C respectively. In October, temperature preference was 7.5" C as compared to 9" C in the field. The variation is explained as a behavioural thermoregulation to direct the fish towards optimal conditions at any time.The seasonal variation in preference temperature can not be ascribed only to seasonal variation in temperature, that is an acclimation phenomenon, but other factors are operative as well, factors which will modify the temperature tolerance in the fish.

“…In some species, a decline in mean preferred temperature occurs in fish left in a gradient more than 4 days (Bacon et al, 1967 ;DeVlaming, 1971 ;Reynolds & Thomson, 1974) . This could result from acclimation temperature exceeding preferred temperature due to behavioural cycling, if these species (Gambusia affinis, Gillichthys mirabilis, and Leuresthes sardina, respectively) show a decrease in preferred temperature at acclimation temperatures above the crossover-point where the two are equal .…”

“…Richards et al, 1977 for a discussion of methodologies and applications and a data tabulation) . It has further been noted (DeVlaming, 1971 ;Reynolds & Thomson, 1974) that the precision of thermoregulation tends to decline over time in extended laboratory experiments, similar to the lack of precision often seen in field thermal distributions . This could be attributed to individual differences in behavioural cycling (and therefore acclimation state) due to non-thermal factors .…”

The final thermal preferendum of fishes: Shuttling behavior and acclimation overshoot

The concept of final preferendum is reexamined in light of data concerning acclimation in a cyclic thermal regime . Because of shuttling behavior' to temperatures above and below the mean preferendum, and because of faster acclimation `upward' thaǹ downward', which result in acclimation to a temperature exceeding the mean of the cycle, a fish may finally gravitate to a preferendum which does not equal acclimation temperature . It is suggested that a distinction be made between the 'crossoverpoint' preferendum, where preference and acclimation are equal, and the 'ultimate' preferendum to which a fish will ultimately gravitate.
