TLDR
In gonad-intact goldfish, sex steroids enhance pituitary responsiveness to GnRH but basal serum GtH-II levels are maintained by a concomitant increase in DA turnover in the pituitsary.About:

Neuroendocrinology of reproduction in teleost fish.
TL;DR: Although precise information as to the physiological effects of KiSS1 in fish, notably on GnRH neurons and gonadotropin release, is still limited, KiSS neurons may emerge as the "gatekeeper" of puberty and reproduction in fish as in mammals.

Neuroendocrine regulation of gonadotrophin II release and gonadal growth in the goldfish, Carassius auratus.
TL;DR: The goldfish, a member of the carp family, is a widely used model for reproductive neuroendocrine studies of economically important fish and the principal stimulatory and inhibitory systems regulating GTH-II release are the gonadotrophin-releasing hormone (GnRH) and dopamine neurones in the preoptic-hypothalamic region.

R.E. Peter,K.L. Yu,K.L. Yu +2 more
TL;DR: This review summarizes the major neuroendocrine mechanisms regulating ovulation, thus providing a basis for understanding the various environmental and hormonal techniques for induction of ovulation of cultured teleosts.
Journal ArticleDOI
Neuroendocrine control of growth hormone in fish.
TL;DR: Results from investigations on a limited number of stimulatory and inhibitory GH-release regulators indicate that activation of different but convergent intrACEllular pathways and the utilization of specific intracellular Ca(2+) stores are some of the strategies utilized.

The Kisspeptin/Gonadotropin-Releasing Hormone Pathway and Molecular Signaling of Puberty in Fish
TL;DR: Temporal patterns of expression in the brain of kiss1r, gnrh2, and gnrh3 and a suite of related genes in the hypothalamo-pituitary-gonadal (HPG) axis were determined and elevated expression of esr1, ar, and cyp19a2 (genes involved in sex steroid signaling) in thebrain at the onset of puberty, and in females slightly in advance of the elevation in the expression ofkiss1r.
