“…In terms of gonadal steroidogenesis, impairment of maturation inducing hormone (Mih, 17α, 20β‐dihydroxy‐4‐pregnen‐3‐one or 17α,20β,21‐trihydroxy‐4‐pregnen‐3‐one, depending on the species) synthesis has been demonstrated for the salmonids S. alpinus , S. salar and O. kisutch (Flett et al ., 1996; Gillet et al ., 2011; Vikingstad et al ., 2016) and the nonsalmonid A. lupus (Tveiten et al ., 2000) during the latter stages of reproductive development. It is not clear what the molecular basis is for reduced synthesis of Mih.…”

Ambient temperature modulates reproductive processes, especially in poikilotherms such as teleosts. Consequently, global warming is expected to impact the reproductive function of fish, which has implications for wild population dynamics, fisheries and aquaculture. In this extensive review spanning tropical and cold‐water environments, we examine the impact of higher‐than‐optimal temperatures on teleost reproductive development and physiology across reproductive stages, species, generations and sexes. In doing so, we demonstrate that warmer‐than‐optimal temperatures can affect every stage of reproductive development from puberty through to the act of spawning, and these responses are mediated by age at spawning and are associated with changes in physiology at multiple levels of the brain–pituitary–gonad axis. Response to temperature is often species‐specific and changes with environmental history/transgenerational conditioning, and the amplitude, timing and duration of thermal exposure within a generation. Thermally driven changes to physiology, gamete development and maturation typically culminate in poor sperm and oocyte quality, and/or advancement/delay/inhibition of ovulation/spermiation and spawning. Although the field of teleost reproduction and temperature is advanced in many respects, we identify areas where research is lacking, especially for males and egg quality from “omics” perspectives. Climate‐driven warming will continue to disturb teleost reproductive performance and therefore guide future research, especially in the emerging areas of transgenerational acclimation and epigenetic studies, which will help to understand and project climate change impacts on wild populations and could also have implications for aquaculture.

“…Hepatoma (RTH149; Kling et al, 2013) and RTG-2 (Ortega-Villaizan et al, 2011) cell lines have been transfected with plasmids at 18°C and 20°C, respectively. However, salmonid steroidogenesis can be altered by a rise in temperature (Gillet et al, 2011), and the use of a non-physiological temperatures for chemical transfection could induce disturbance of some functions, such as steroidogenesis.…”

“…In our experimental conditions, the hormone injections were administered at lower temperatures, from 3 to 4.6°C. There is strong evidence that elevated temperature can modulate the effects of endocrine rhythms in salmonids (Gillet et al, 1996;Pankhurst and Thomas, 1998;Taranger et al, 2003;King and Pankhurst, 2004a, b;Gillet and Breton, 2009;Gillet et al, 2011). These effects also have the capacity to influence the efficacy of hormone treatment.…”

ABSTRACT:The effect of single and double injections of D-Tle 6 ,Pro 9 ,NEt-mGnRHa (Supergestran ® ) on advancement and induction of ovulation in Arctic grayling was assessed. Sexually mature wild Arctic grayling females (most 2-4 years old) were caught in the Yenisey River at the beginning of May 2010. After a 4-day acclimatization, the females were randomly divided into four groups and intramuscularly injected as follows: group A, control group, treated with physiological saline only; group B, treated with a single injection (SI) of Supergestran ® at 25 µg/kg body weight (BW); group C, injected twice (DI) with 25 µg/kg BW 3 days apart; group D, injected twice with 10 µg/kg BW 3 days apart. After stripping, the pseudo-gonadosomatic index was calculated, and an eggs sample from each female was fertilized. Only fish in the groups treated with DI protocols ovulated. No differences between the two groups were found in the timing of ovulation, ovulation rate, or mean time to ovulation. No females in either group A or B ovulated, since the experiment had to be prematurely terminated due to technical problems at the field hatchery. The DI of 10 µg/kg proved sufficient to induce and advance ovulation in Arctic grayling. Hormone treatments seem to be a promising tool to obtain viable eggs of Arctic grayling in a short time window and thereby to ensure satisfactory numbers of fry for restocking programs.
