Journal ArticleDOI
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.
Journal ArticleDOI
Endocrine manipulations of spawning in cultured fish: from hormones to genes
TL;DR: Based on the recent discovery of GnRH multiplicity in fish and the increasing understanding of its functional significance, new GnRH agonists can be designed for more potent, affordable and physiologically-compatible spawning induction therapies.
Book ChapterDOI
7 The Gonadal Steroids
TL;DR: This chapter discusses that the gonads potentiality to produce steroids, and the regulation of the syntheses; and the actual physiological role of gonadal steroids in fish is discussed with emphasis on gametogenesis.
Journal ArticleDOI
Use of GnRHa-delivery systems for the control of reproduction in fish
TL;DR: Future research should focus on the optimization of thistechnology in terms of using the mostpotent GnRHa-delivery systems, identifying the mostappropriate GnR Ha release kinetics according to the reproductive biology of different species, and determining minimum effective doses.
Journal ArticleDOI

TL;DR: Sea bream brains have three forms of GnRH, one of which is described herein and is called sea bream GnRH (sbGnRH), andylogenetic distribution of Gn RH peptides suggests sbGnRh arose in the perch-like fish as a gene duplication of the existing cGn RH-II or salmon GnRH genes.
