“…Similarly, the exposure of larvae to the same magnetic fields between 11 and 14 days post fertilization led to desynchronization of Cry1aa and Per1b circadian oscillations (Oliva et al, 2019). A number of studies have revealed an influence of magnetic and electromagnetic fields on molecular oscillators and circadian behaviour in other species (Manzella et al, 2015;Sallam et al, 2016;Agliassa & Maffei, 2019;Bartos et al, 2019). Magnetic fields did affect zebrafish behaviour in short-term experiments (Osipova et al, 2016;Cresci et al, 2018;Myklatun et al, 2018).…”

Over recent decades, changes in zebrafish (Danio rerio) behaviour have become popular quantitative indicators in biomedical studies. The circadian rhythms of behavioural processes in zebrafish are known to enable effective utilization of energy and resources, therefore attracting interest in zebrafish as a research model. This review covers a variety of circadian behaviours in this species, including diurnal rhythms of spawning, feeding, locomotor activity, shoaling, light/dark preference, and vertical position preference. Changes in circadian activity during zebrafish ontogeny are reviewed, including ageing-related alterations and chemically induced variations in rhythmicity patterns. Both exogenous and endogenous sources of inter-individual variability in zebrafish circadian behaviour are detailed. Additionally, we focus on different environmental factors with the potential to entrain circadian processes in zebrafish. This review describes two principal ways whereby diurnal behavioural rhythms can be entrained: (i) modulation of organismal physiological state, which can have masking or enhancing effects on behavioural endpoints related to endogenous circadian rhythms, and (ii) modulation of period and amplitude of the endogenous circadian rhythm due to competitive relationships between the primary and secondary zeitgebers. In addition, different peripheral oscillators in zebrafish can be entrained by diverse zeitgebers. This complicated orchestra of divergent influences may cause variability in zebrafish circadian behaviours, which should be given attention when planning behavioural studies.

“…7,12,13 The locomotor activity rhythm is considered a reliable marker of the circadian output and the main index that reflects the sleep-wake cycle and the general behavior in mammals. [14][15][16] Recording the locomotor activity patterns has been used to analyze possible dysfunctions of the circadian system in patients with cancer and after applying the cancer treatment protocols. 17,18 Rhythmic secretion of glucocorticoids is another important marker for circadian output.…”

“…However, there were also some flies with shortened periods [ 18 ]. A phase shifting and a significantly increased acrophase of locomotor activity rhythms were registered in rats exposed to radiofrequency magnetic fields [ 19 ]. Beyond the behavioral rhythms, magnetic fields altered circadian clock gene expression [ 20 , 21 ].…”

The influence of magnetic fields and natural geomagnetic storms on biological circadian rhythms are actively studied. This study reveals an impact of local natural perturbations in the geomagnetic field that occurred at different times of the day on circadian patterns of locomotor activity of zebrafish. A decrease in zebrafish swimming speed was observed during the geomagnetic disturbances before or after the fluctuations of diurnal geomagnetic variation. However, if the geomagnetic perturbations coincided with the fluctuations of diurnal geomagnetic variation, the decrease in zebrafish swimming speed was insignificant. This result suggests that the biological effects of geomagnetic disturbances may depend on synchronization with the diurnal geomagnetic variation. It implies that the previously published correlations between geomagnetic activity and medical or biological parameters could result from a disruption in circadian biorhythms.
