“…The thermal experience of fish, especially during early life, can shape HPI responsiveness on further stressors (Mateus et al ., 2017a; Mills et al ., 2015). Research effort is needed to understand how exposure to elevated temperatures during early life may affect the capacity to cope with the various threats caused by global warming (Mateus et al ., 2017a; Wassink et al ., 2019; Whitney et al ., 2013).…”

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.

“…The reduction of viable pre-hatching eggs translates into reduced juvenile recruitment 29 . Furthermore, an early exposure to maternal GC levels during embryonic development causes permanent modification of the offspring’s HPA/I axis, and may impact future responses to environmental stressors, which may or may not be adaptive, and also may cause trade-offs between life-history traits later in life 48 , 49 . The duration of the environmental perturbation will also play an important role on the extent of the demographic consequences of physiological stress.…”

Cascading effects of thermally-induced anemone bleaching on associated anemonefish hormonal stress response and reproduction

Organisms can behaviorally, physiologically, and morphologically adjust to environmental variation via integrative hormonal mechanisms, ultimately allowing animals to cope with environmental change. The stress response to environmental and social changes commonly promotes survival at the expense of reproduction. However, despite climate change impacts on population declines and diversity loss, few studies have attributed hormonal stress responses, or their regulatory effects, to climate change in the wild. Here, we report hormonal and fitness responses of individual wild fish to a recent large-scale sea warming event that caused widespread bleaching on coral reefs. This 14-month monitoring study shows a strong correlation between anemone bleaching (zooxanthellae loss), anemonefish stress response, and reproductive hormones that decreased fecundity by 73%. These findings suggest that hormone stress responses play a crucial role in changes to population demography following climate change and plasticity in hormonal responsiveness may be a key mechanism enabling individual acclimation to climate change.

“…By comparison, prior work in warmer water has shown recovery to be complete by 4 h; for instance, a study of largemouth bass exercised at 10°C showed complete recovery of plasma cortisol and glucose levels by 2 h ) and work on northern pike has shown recovery of muscle lactate levels by 1 h (Arlinghaus et al 2009). The course of recovery of plasma metrics may be directly dictated by temperature, possibly due to reduced enzymatic activity in cold conditions (Van Ham et al 2003;Mills et al 2015). For instance, a study of Atlantic salmon Salmo salar L., Wilkie et al (1997) found recovery of plasma lactate levels by 4 h at relatively warmer temperatures (18°and 23°C), but not at lower temperatures (12°C).…”

Understanding how released fish recover following capture is vital information for researchers examining the effects of angling on exploited populations. This information is virtually non‐existent for fish angled through the ice in winter, despite the popularity of ice‐angling in many northern areas. To address this gap, 60 northern pike, Esox lucius L., were angled through the ice from an impoundment in eastern Wisconsin, USA, and subjected to one of ten combinations of handling and recovery duration. Plasma samples were collected and analysed for cortisol, lactate and glucose. The results showed a delayed response in the elevation of plasma variables, and a significant interaction between air exposure and recovery time for plasma lactate. No fish suffered mortality during the period of holding. Collectively, these data suggest that northern pike are physiologically resilient to ice‐angling capture stress as long as air exposure times are kept at 4 min or less.
