High water temperature impairs ovarian activity and gene expression in the brain–pituitary–gonadal axis in female red seabream during the spawning season

TLDR
High water temperature is the proximate driver of the termination of the spawning season of female red seabream and appears to be mediated by suppression of gene expression in the B-P-G axis.About:

From gametogenesis to spawning: How climate‐driven warming affects teleost reproductive biology
TL;DR: It is demonstrated 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.

Temperature affects sexual maturation through the control of kisspeptin, kisspeptin receptor, GnRH and GTH subunit gene expression in the grass puffer during the spawning season.
TL;DR: The present results indicate that anomalous temperature have an inhibitory effect on reproductive function through suppressing kiss2/kiss2r/gnrh1/fshb and lhb expression and these changes may occur in a normal physiological response as well as in a malfunctional stress response.
Journal ArticleDOI
Effects of water temperature on perchlorate toxicity to the thyroid and reproductive system of Oryzias latipes
TL;DR: The observations indicate that exposure to perchlorate could affect thyroid function and overall reproductive fitness, and these effects could be aggravated under high water temperatures.

Capture, adaptation and artificial control of reproduction of Lophiosilurus alexandri: A carnivorous freshwater species.
Deliane Cristina Costa,Walisson de Souza e Silva,Reinaldo Melillo Filho,Kleber Campos Miranda Filho,José Cláudio Epaminondas dos Santos,Ronald Kennedy Luz +5 more
TL;DR: The present study describes the capture adaptation and reproduction of wild Lophiosilurus alexandri broodstock in laboratory conditions and contributes to the understanding of the reproductive biology of this endangered species during captivity.

Daily rhythms of the expression of genes from the somatotropic axis: The influence on tilapia (Oreochromis niloticus) of feeding and growth hormone administration at different times.
Leandro Santos Costa,Priscila Vieira Rosa,Rodrigo Fortes-Silva,F. Javier Sánchez-Vázquez,José Fernando López-Olmeda +4 more
TL;DR: The first report that describes the existence of daily rhythms in the somatotropic axis of tilapia and its time-dependent responses of GH administration is described.

TL;DR: Puberty comprises the transition from an immature juvenile to a mature adult state of the reproductive system, i.e. the individual becomes capable of reproducing sexually for the first time, which implies functional competence of the brain-pituitary-gonad (BPG) axis.
Journal ArticleDOI
Effects of climate change on fish reproduction and early life history stages
TL;DR: A companion effect of marine climate change is ocean acidification, which may pose a significant threat through its capacity to alter larval behaviour and impair sensory capabilities, which in turn impacts on population replenishment and connectivity patterns of marine fishes.

TL;DR: The effect of temperature on protein metabolism in fish: the possible consequences for wild Atlantic salmon stocks in Europe as a result of global warming and the effects of climate change on cod stocks are discussed.
Journal ArticleDOI
Stress and fish reproduction: The roles of allostasis and hormesis
TL;DR: This paper is a review of the effects of stress on reproduction in fishes and the concept of hormesis is a useful way to think about the effect of stressors on fish reproduction since responses can be nonmonotonal, often biphasic.
