“…A static field of 10 mT and a 50 Hz EMF of 1 mT caused developmental instability in the inner ear organ. The rainbow trout, incubated and reared in fields of such values for 13 days in the egg stage and 24 days in the larval stage, showed a fluctuating asymmetry of otolith size, and a higher significance occurred in the youngest larvae (five days after hatching) [63].…”

The number of sources of anthropogenic magnetic and electromagnetic fields generated by various underwater facilities, industrial equipment, and transferring devices in aquatic environment is increasing. These have an effect on an array of fish life processes, but especially the early developmental stages. The magnitude of these effects depends on field strength and time of exposure and is species-specific. We review studies on the effect of magnetic fields on the course of embryogenesis, with special reference to survival, the size of the embryos, embryonic motor function, changes in pigment cells, respiration hatching, and directional reactions. We also describe the effect of magnetic fields on sperm motility and egg activation. Magnetic fields can exert positive effects, as in the case of the considerable extension of sperm capability of activation, or have a negative influence in the form of a disturbance in heart rate or developmental instability in inner ear organs.

“…FA is also useful as an indicator of larval fish condition (Grønkjaer & Sand, 2003;Somarakis et al, 1997b) and stress (Gagliano et al, 2008;Lemberget & McCornick, 2009;Castillo-Hidalgo et al, 2018;Landaeta et al, 2018), even if the results obtained by Castillo-Hidalgo et al (2018) were inconsistent. Most recently, Fey et al (2020) showed for larval trout the significant effect of a magnetic field of 10 mT on otolith FA of larval trout. The opposite result of larval fish growth rate having no effect on FA is also available (Folkvord et al, 2000;Fey & Hare, 2008;Kristoffersen & Magoulas, 2009;Zenteno et al, 2014).…”

“…Assuming environmental stress causes developmental instabilities, high fluctuating asymmetry can indicate the lower condition of larvae that experienced unfavourable environments. The link between fish condition and fluctuating asymmetry has been studied in both adult and larval fish, and a number of measurements have been analysed, including otolith size and shape (Escós et al,1995;Somarakis et al, 1997a, b;Fey et al, 2020). However, the results obtained in different studies are inconsistent.…”

Cannibalism can be a significant factor limiting the survival of pike, Esox lucius, early life stages in both natural and aquaculture conditions. In the present research, type I cannibalism was studied in pike larvae (size range: 9-32.5 mm standard length, SL) in controlled conditions for 45 days post-hatching (dph). For this purpose, the occurrence of cannibalistic pairs, i.e. prey caught by a cannibal inside the cannibal's mouth, was monitored for 15 min periods by two observers six times daily. Cannibalism was not observed in fish that still had yolk-sacs, but it did occur as soon as the yolk-sac was absorbed on 5 dph at a body size of 13 mm at 22°C and 10 dph at a body size of 13.4 mm at 15°C. The ratio of prey to predator size was on average 87%, but the smallest observed size difference was only 1.3%. The intensity of cannibalistic attacks depended on water temperature with more intense cannibalism at 22°C than at 15°C, and no cannibalism at 10°C. Fluctuating asymmetry (FA) in all three sagittal otolith size parameters (area, width, and length) was higher in prey than in cannibals, the differences were not statistically significant.
