“…Many animals have evolved cycles of activity and quiescence in accordance with the daily photoperiod, which is a major ‘zeitgeber’ (German for ‘timekeeper’) ( Reebs, 2002 ; Steindal and Whitmore, 2019 ). The observed variation in activity and rest is tied to the production of melatonin, a molecule that is hugely important for the synchronisation of sleep–wake cycles ( Gandhi et al, 2015 ; Perry, 2022 ). Genes coding for melatonin production respond to the outputs of pineal photodetection cells ( Kuz'mina, 2020 ), with changes in photoperiod affecting melatonin synthesis ( Perry, 2022 ), and the effects of melatonin production differing between diurnal and nocturnal species ( López-Olmeda et al, 2006 ).…”

It should be noted, however, that this first criterion, and the regulation of sleep as whole, is intrinsically tied to sleep homeostasis.…”

Evidence of behavioural sleep has been observed in every animal species studied to date, but current knowledge of the behaviour, neurophysiology and ecophysiology associated with sleep is concentrated on mammals and birds. Fish are a hugely diverse group that can offer novel insights into a variety of sleep-related behaviours across environments, but the ecophysiological relevance of sleep in fish has been largely overlooked. Here, we systematically reviewed the literature to assess the current breadth of knowledge on fish sleep, and surveyed the diverse physiological effects and behaviours associated with sleep. We also discuss possible ways in which unstudied external factors may alter sleep behaviours. For example, predation risk may alter sleep patterns, as has been shown in mammalian, avian and reptilian species. Other environmental factors – such as water temperature and oxygen availability – have the potential to alter sleep patterns in fish differently than for terrestrial endotherms. Understanding the ecological influences on sleep in fish is vital, as sleep deprivation has the potential to affect waking behaviour and fitness owing to cognitive and physiological impairments, possibly affecting ecological phenomena and sensitivity to environmental stressors in ways that have not been considered.
