“…An increase of locomotor activity of fish in a plus-shaped maze, increases in number of seismosensory system openings in mandibular and preopercular bones of underyearlings, a decrease in number of rays in the anal fin, and redistribution of vertebrae between the sections of the vertebral column were observed after exposing embryos to shifts in the diurnal geomagnetic variation relative to the night-day light cycle [Krylov et al, 2017]. These effects are very similar to the effects of simulated geomagnetic storm on roach embryos described earlier [Krylov et al, 2010a;Talikina et al, 2013;Osipova et al, 2016]. In other words, the complex of responses in R. rutilus to shifts in diurnal geomagnetic variation obtained at different ages was similar to the complex of responses to simulated geomagnetic storms.…”

This review presents contemporary data on the biological effects of geomagnetic activity. Correlations between geomagnetic indices and biological parameters and experimental studies that used simulated geomagnetic storms to detect possible responses of organisms to these events in nature are discussed. Possible mechanisms by which geomagnetic activity influences organisms are also considered. Special attention is paid to the idea that geomagnetic activity is perceived by organisms as a disruption of diurnal geomagnetic variation. This variation, in turn, is viewed by way of a secondary zeitgeber for biological circadian rhythms. Additionally, we discuss the utility of cryptochrome as a biological detector of geomagnetic storms. The possible involvement of melatonin and protein coding by the CG8198 gene in the biological effects of geomagnetic activity are discussed. Perspectives for studying mechanisms by which geomagnetic storms affect organisms are suggested. Bioelectromagnetics. 38:497-510, 2017. © 2017 Wiley Periodicals, Inc.

“…These data are consistent with results of our preliminary experiment. An exposure of roach embryos in a simulation of a moderate geomagnetic storm in the direction of the horizontal component during the first 48 hpf led to a decrease in the L S –M T indices and to redistribution of the vertebral number in sections of the vertebral column (Krylov et al ., ). In addition, the influence of anthropogenic low‐frequency magnetic fields on roach embryos was studied using the same approaches for 6 years (Krylov et al ., ).…”

This study presents data collected over a 3 year period on the effects of simulated geomagnetic storms (SGMS) on Eurasian roach Rutilus rutilus embryos. Effects were studied during different stages of early development. Rutilis rutilus were raised in ponds for 4 months after exposure to SGMS. The mass, standard length and morphological characteristics of under-yearlings exposed as embryos were recorded. A decrease in length-mass indices in under-yearlings was noted after they had been exposed to SGMS during the first 2 days or during the third and fourth days of early development. Near the time point of 48 h post fertilisation, either no effect or an increased size was observed. In addition, exposure to SGMS led to a redistribution of the vertebral number between the sections of the vertebral column as well as changes in the number of seismosensory system openings in the mandibular and praeoperculum bones of under-yearlings. Observed effects are similar to previously published data on the influence of anthropogenic magnetic fields on roach, namely changes in linear-mass indices, number of vertebrae and number of seismosensory system openings in the mandibular bones of under-yearlings exposed as embryos. Possible mechanisms of magnetic influence on early development of fish are discussed.

“…A 25 min exposure of R. rutilus eggs to a strong magnetic storm during cleavage with embryonic cells at the blastula stage resulted in an increase in the number of cells in the anaphase + telophase compared with the cells in the prophase + metaphase. When embryos of R. rutilus were exposed to an induced magnetic storm from the moment of fertilisation to the period of organogenesis, the effects seen at the fry stage were a significant difference in body length, mass, number of rays in ventral and anal fins as well as the number of transitional and caudal‐spine bones in the fry compared with controls (Krylov et al, ).…”

Magnetoreception is the ability of organisms to perceive magnetic fields in the surrounding environment and changes in its properties such as field direction, intensity and gradient, where the effect on organisms can manifest as an array of reactions. As the magnetic sense is found in many taxa, both evolutionarily young and old, it can be assumed that magnetoreception came into existence as one of the first sensory systems. Many studies on the effect of magnetic fields on fishes have considered both fishes that migrate for long distances and those that are more or less sedentary. Research has focused on tracing the perception of the geomagnetic field by fishes and understanding magnetic fields that are smaller and larger than the ambient Earth's geomagnetic field. The question of the effect of magnetic fields of values higher than the Earth's is gaining importance with the increasing effect of anthropogenic magnetic and electromagnetic fields in aquatic ecosystems. This review draws together the results of studies on the effect and reception of natural and human‐generated magnetic fields on fishes at various stages of ontogeny, chronologically arranged from gametes, through embryonic development, embryonic and larval motor function, directional reactions of embryos and larvae, orientation of fishes, to the mechanisms of magnetic field reception. The present state of knowledge indicates a common nature of effect on various ontogenetic stages of fishes. However, understanding of the mechanisms of magnetic sense in fishes and its relevance for ecological outcomes highlights that further progress requires more detailed research.
