TLDR
The behavioural and metabolic responses of the largemouth bass Micropterus salmoides (Lacepede) to temperature were determined to define optimal thermal conditions and the results are discussed in relation to the use of this information in aquaculture.Abstract:
The behavioural and metabolic responses of the largemouth bass Micropterus salmoides (Lacepede) to temperature were determined to define optimal thermal conditions. The final preferendum of largemouth bass juveniles determined with acute and gravitation methods was independent of the method (29.0–28.1 °C). The displacement velocity in the horizontal thermal gradient of bass juveniles was 22.4 cm h−1 in the light phase and 22.6 cm h−1 in the dark phase. Oxygen consumption rates in the largemouth bass increased significantly (P<0.05) from 48.8 to 69.4 mg O2 Kg−1 h−1 with an increase in the acclimation temperature from 20 to 33 °C. The temperature quotient (Q10) in the juveniles was 1.37–2.00 in the range of acclimation temperatures of 26–29 and 29–32 °C. The optimum temperature range for growth calculated using Jobling's equation was 28.1–28.6 °C and for Q10 values 26–29 °C. The results are discussed in relation to the use of this information in aquaculture.read more

TL;DR: The current data show that the sea bass population possesses acclimation response ratio (ARR) values (0.25–0.27) similar to some tropical species, suggesting that cold winter temperatures may not pose danger during the culture of European sea bass in deep ponds or high water exchange rate systems.

Temperature as an Ecological Resource
TL;DR: It is suggested that viewing temperature and other niche axes in the way ecologists have viewed food resources would be useful, and if animals successfully compete for their thermal niche, growth and perhaps other measures of fitness are maximized.
