“…With regard to cortisol, basal blood levels are reported to be greater, overall, under prolonged exposure to elevated temperatures (Kim et al, 2019;Madaro et al, 2018;Samaras et al, 2018) (Figure 2). (Gallant et al, 2017;Kandalski et al, 2018;Ryan, 1995;Samaras et al, 2018;Steinhausen et al, 2008), but exceptions to that general pattern have been observed (Davis, 2004;Samaras et al, 2018).…”

“…With regard to cortisol, basal blood levels are reported to be greater, overall, under prolonged exposure to elevated temperatures (Kim et al ., 2019; Madaro et al ., 2018; Samaras et al ., 2018) (Figure 2). However, alternative results have occasionally been observed, for example in the Emerald rockcod Trematomus bernacchii Boulenger 1902, which showed no changes in cortisol basal values on acclimation to warmer water (up to +3.8°C) (Hudson et al ., 2008) (Table 1).…”

“…These effects can be partially mediated by stress‐induced immune alterations (Tort, 2011; Yada & Tort, 2016). Those alterations include immune depression and higher susceptibility to infection and disease (Kandalski et al ., 2018; Kim et al ., 2019; Li et al ., 2019; Martínez et al ., 2018). In addition, it is important to note that global warming can lead to the emergence of novel infectious agents, triggering diseases for which fishes are not yet adapted (Marcos‐López et al ., 2010).…”

The capacity of fishes to cope with environmental variation is considered to be a main determinant of their fitness and is partly determined by their stress physiology.By 2100, global ocean temperature is expected to rise by 1-4 C, with potential consequences for stress physiology. Global warming is affecting animal populations worldwide through chronic temperature increases and an increase in the frequency of extreme heatwave events. As ectotherms, fishes are expected to be particularly vulnerable to global warming. Although little information is available about the effects of global warming on stress physiology in nature, multiple studies describe the consequences of temperature increases on stress physiology in controlled laboratory conditions, providing insight into what can be expected in the wild. Chronic temperature increase constitutes a physiological load that can alter the ability of fishes to cope with additional stressors, which might compromise their fitness. In addition, rapid temperature increases are known to induce acute stress responses in fishes and might be of ecological relevance in particular situations. This review summarizes knowledge about effects of temperature increases on the stress physiology of fishes and discusses these in the context of global warming.

“…Recent increases in water temperature due to climate change have had a profound effect on aquatic ectotherms, including teleosts (Lee et al, 2014;Alfonso et al, 2021). Fish adapt to changes in water temperature by controlling the rate of metabolic activities, although the fish must maintain their biological activity within tolerable thermal limits (Radoslav et al, 2013;Kim et al, 2019). Temperatures above tolerance thresholds can lead to changes in growth rate, enzymatic activities, and metabolic rate, leading to homeostatic overload or failure.…”

Water temperature is the most important factor in fish farming as changes in water temperature cause physiological stress in fish. There have been few studies on physiological responses to high temperatures, which vary with aging. This study investigated the responses of juvenile and adult Platichthys stellatus to heat stress. Plasma cortisol, glucose, lactate, and lysozyme levels, antioxidant enzyme activities, and expression of heat shock proteins 70 and 90 (HSP70 and HSP90) of P. stellatus were determined at water temperatures of 16, 20, 24, 28, and 30°C. As a result, it was confirmed that several plasma parameters of adult were significantly higher than that of juvenile under heat stress. Plasma cortisol and glucose levels of adult were increased than juvenile at 24 and 28°C. Plasma lactate level of adult were higher than that of juvenile at 28°C. Comparisons of survival and physiological changes showed that juveniles have better thermal tolerance, resulting in a higher cumulative survival rate. Moreover, the relationship between thermal tolerance and HSP gene expression revealed that expression of HSP70 and HSP90 was significantly upregulated at 28°C in both juvenile and adult fish, and HSP70 expression was significantly higher in juvenile fish than in adult fish. It is judged that the adult's HSP70 activity was lower than juvenile, so the demand for plasma parameters for heat response was relatively high, whereas juvenile's HSP70 activity increased at 24 and 28°C, indicating a relatively stable value of plasma parameters. These results indicate that the thermal tolerance of juvenile fish is greater than that of adult fish, based on the differences in plasma parameters and HSP expression. These findings improve our understanding of age-related changes in P. stellatus during thermal stress and may help guide the management of fish farms.
