“…Longer day lengths and lower temperatures induced higher proportions of females. This is the first case of a photoperiod-dependent sex determination system in fish [Brown et al, 2014]. Temperature and photoperiod seem to act in synergy in this fish to determine the sexual phenotype.…”

“…In the Californian grunion fish, Leuresthes tenuis [Brown et al, 2014], both temperature and photoperiod can influence the sex ratio. However, because the seasonal thermal variation is very low (4 ° C) along the North American Pacific coast, photoperiod has become a more informative cue of season length than temperature.…”

Fish sex reversal is a means to understand sex determination and differentiation, but it is also used to control sex in aquaculture. This review discusses sex reversal in gonochoristic fish, with the coexistence of genetic and environmental influences. The different periods of fish sensitivity to sex reversal treatments are presented with the mechanisms implicated. The old players of sex differentiation are revisited with transcriptome data and loss of function studies following hormone- or temperature-induced sex reversal. We also discuss whether cortisol is the universal mediator of sex reversal in fish due to its implication in ovarian meiosis and 11KT increase. The large plasticity in fish for sex reversal is also evident in the brain, with a reversibility existing even in adulthood. Studies on epigenetics are presented, since it links the environment, gene expression, and sex reversal, notably the association of DNA methylation in sex reversal. Manipulations with exogenous factors reverse the primary sex in many fish species under controlled conditions, but several questions arise on whether this can occur under wild conditions and what is the ecological significance. Cases of sex reversal in wild fish populations are shown and their fitness and future perspectives are discussed.

“…The annual photoperiod cycle is the main environmental zeitgeber influencing the reproductive cycle of salmonids (Taranger et al, ). Previous studies have demonstrated that the manipulation of photoperiod affects reproduction, growth rate and feeding behaviour in several species of salmonids without negative consequences (Boeuf & Le Bail, ; Brown, Baumann, & Conover, ). The primary mechanism underlying the delay of sexual maturation with photoperiod manipulation in salmonids remains unclear (Liu & Duston, ; Taranger et al, ), but it is suggested that the intensity and spectrum of light exposure affect the physiological responses of teleosts in areas such as growth, reproduction, behaviour and stress resistance (Boeuf & Le Bail, ; Karakatsouli et al, ; Migaud, Davie, & Taylor, ).…”

The effect of timing of extended photoperiod on growth and maturity of brook trout ( Salvelinus fontinalis )

et al. 2019

The influence of timing of extended photoperiods on growth and maturity of brook trout was investigated in a 112‐day experiment. The fish with mean initial weight of ~192 g were reared under four light regimes: one control group with natural ambient photoperiod and three groups exposed to an 18L:6D regime initiated at days 1, 23 or 46 of the growth trial. Light‐emitting diodes, with intensity of 250–1000 lux, depending on the distance from the light source, were used for extending light periods. There was a positive effect of prolonged day length on fish growth (p < 0.05), and a delay in gonad development and sexual maturity. Significantly higher numbers of sexually mature fish were found among controls groups, regardless of sex. Survival rate was not affected by light regime. This study demonstrated that the short‐term expansion of the photo period delayed maturation and increased the growth rate of brook trout.

“…Therefore, determination of optimal environmental conditions would result in improved larval growth and survival rate and reduced rearing period and production cost. Among environmental factors, photoperiod is the most controllable variable in rearing condition and is well known to influence overall larval performance including feeding activity (Karlsen, Skiftesvik & Helvik, ), growth and survival (Barlow, Pearce, Rodgers & Clayton, ; Giri et al., ; Karakatsouli et al., ; Pedro Cañavate, Zerolo & Fernández‐Díaz, ; Puvanendran & Brown, ; Solbakken & Pittman, ; Stuart & Drawbridge, ; Villamizar, García‐Alcazar & Sánchez‐Vázquez, ), health (Kitawa et al., ), behaviour (Karlsen et al., ), swimming performance (Smiley & Parsons, ) and even sex ratio (Brown, Baumann & Conover, ). The response of fish larvae to photoperiod is a species‐specific characteristic and even their requirement to light may vary as they grow (Barlow et al., ; Boeuf & Bail, ; Puvanendran & Brown, ; Vallés & Estévez, ).…”

Growth, development and behaviour of Persian sturgeon Acipenser persicus larvae in different light regimes

et al. 2017

The effects of five different light regimes on growth performance and behaviour of Persian Sturgeon larvae were examined. Larvae were reared under five different photoperiods (24L, 12L:12D, 16L:8D, 8L:16L and 24D), from hatching (25.8 ± 8.1 mg; 12 ± 0.6 mm) to 28 days post‐hatch (dph). Except the last week, there was no significant difference in growth parameters among the experimental groups. Growth performance significantly improved in larvae reared under a continuous light regime. The highest final length (34.5 ± 1.7 mm) was measured in 24L and the lowest one (29.5 ± 0.4 mm) in the constant darkness. Relative to other experimental groups, the continuous darkness had a retarding impact on the yolk sac absorption and swarming behaviour. Among the whole body compositions, the lowest body moisture content was measured in the continuous light group. Persian Sturgeon pre‐larvae and larvae were not completely dependent on light regimes (in 1–21 days), whereas on the basis of measured parameters (total length, wet and dry weight and digestive fullness index) a continuous light regime played a decisive role on growth performance beyond 21 dph.
