“…Otherwise, the use of low‐level laser therapy (600–700 nm) is a very useful tool for improving the proliferation rate of various cell lines, being applied for this purpose in fields such as tissue engineering and regenerative medicine (AlGhamdi, Kumar, & Moussa, ). Regarding spermatozoa, Light irradiation it has been reported to have beneficial effects on motility and kinetic parameters in tilapia fish, ram, dog and buffalo spermatozoa (Abdel‐Salam et al, ; Corral‐Baqués, Rigau, et al, ; Zan‐Bar et al, ), and also, an increase in the long‐term storage longevity o turkey spermatozoa was reported (Iaffaldano, Meluzzi, Manchisi, & Passarella, ). With respect to boar spermatozoa, a study reported no differences in the photostimulation of 90 ml seminal doses (Luther, Thi, Schäfer, Schulze, & Waberski, ).…”

Pre‐treatment of boar semen with a red light photostimulation procedure increases its “in vivo” fertilising ability. However, “in vitro” conducted studies shown contradictory results regarding the ability of photostimulated spermatozoa to react against strong stress and to achieve the capacitation status. The aim here was to determine the effect of photostimulation on the response to short‐term moderate thermal stress of boar semen. Boar semen was exposed to red LED light regime emitting a 620–630 nm during 10 min of light, 10 min of rest and 10 min of light after 3 hr since semen was collected. An aliquot without photostimulation was included as a control. After the photostimulation, the sperm cells were incubated for 15 min at 37°C. Afterwards, motility, viability, intracellular Ca2+ level and production of reactive oxygen species (ROS) and peroxynitrite were analysed. The results showed that the photostimulated group maintained total motility throughout the time, whereas a significant decrease in total motility was observed in the nonphotostimulated control group. Furthermore, for kinetic parameters of motility, a significant increase was observed in LIN, STR and WOB in photostimulated spermatozoa. Peroxynitrite production was significantly increased in the photostimulated spermatozoa, whereas viability, ROS production and intracellular Ca2+ levels were not affected by photostimulation. In conclusion, photostimulation of commercial boar semen has a positive effect on motility of spermatozoa subjected to a short‐term moderate thermal stress, which was concomitant with an increase in peroxynitrite production.

We present data on the effect of polarized laser radiation in the near IR region of the spectrum with wavelength 808 nm on the resistance of juvenile sturgeon to oxygen deficiency in the habitat when the fertilized roe are briefly exposed to radiation in the organogenesis stage. The magnitude of the stimulating effect depends on the exposure time (t) and power density (P) of the radiation and also on its modulation frequency (F). For optimal irradiation parameters (cw mode, P = 2.9 mW/cm 2 , t = 60 sec), the hardiness of the juveniles increases by a factor of ~1.5 compared with the control group. The maximum differences in the sensitivity of embryos to cw and pulsed radiation are observed for F = 1 Hz; as the modulation frequency increases up to F = 50 Hz, the magnitude of the photobiological effect approaches a level typical for cw exposure. We show that the duration of the dark period (pause time) between pulses is the critical parameter determining the dependence of the stimulating effect on the modulation frequency. We discuss questions concerning use of the indicated physical factor in the technology for raising sturgeon under industrial fish farming conditions. Introduction. Economically sound technologies for industrial raising of valuable fish species (sturgeon, salmon, whitefish) have attracted the attention of an increasing number of fish farms [1][2][3]. In this case, fish farming efficiency is mainly determined by the hardiness of the juvenile at the time it is released into artificial and natural bodies of water, in which it is subject to the effect of diverse biotic and abiotic habitat factors. The concentration of dissolved oxygen is an important factor in an aquatic environment, which fluctuates significantly both under artificial conditions and under farm conditions for raising a standard fish juvenile. When there is a deficiency of oxygen dissolved in the water, for the farm-raised juvenile we may observe a number of morphological deviations: head deformities, microcephaly (reduced brain size), underdeveloped gills, defects in the olfactory organs, etc. Most often, such a fish considerably lags behind normally developing individuals in size-weight parameters [1]. Furthermore, a significant deficiency of oxygen dissolved in the water can cause large-scale kills of fish fry. This is why development of methods for improving the resistance of juvenile fish to oxygen deficiency is an important problem in modern fish farming practice. There are quite good grounds for the interest of ichthyologists [4][5][6][7][8][9][10][11] in the stimulating effect of optical (including laser) radiation, which has been successfully used for a long time for treatment of human diseases [12,13], treatment and stimulation of weakened animals [14,15], and also for stimulation of plants [16,17].

“…ROS are responsible for mediating the effects of light [13]. ROS are known as double edged swords in animal reproduction as higher levels of ROS can lead to sperm death due to depletion of ATP and lipid peroxidation leading to oxidative stress [55] and moderate ROS levels regulate various physiological functions of sperm such as hyperactivation, capacitation, acrosomal reaction and zona binding [54,55].…”
