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

Highlights • The kiss2 and kiss2r along with gnrh1 were significantly decreased at both low and high temperature. • The fshb and lhb were significantly decreased in both low and high temperature. • Plasma levels of cortisol were significantly increased in low temperature but not in high temperature....

Zusammenfassung:	Highlights • The kiss2 and kiss2r along with gnrh1 were significantly decreased at both low and high temperature. • The fshb and lhb were significantly decreased in both low and high temperature. • Plasma levels of cortisol were significantly increased in low temperature but not in high temperature. • Anomalous low and high temperature may shut down the reproduction through suppression of kisspeptin/GnRH1/GTH system.
