Figure outlining limiting values of oxygen saturation at 4-20°C. The values are based on known minimum levels that ensure normal activity in healthy, unstressed post-smolts, based on worked carried out by Remen et al. (2016), which represent the border between red and orange levels. In order to account for variation in oxygen demand which may be related to health status, stress levels etc., a margin of 10% has been added for the yellow level and 20% for the green level.
