Puberty in teleosts

Puberty is the process by which animals acquire for the first time the ability to reproduce. In teleost fishes, an understanding of the mechanism underlying pubertal development is important not only for basic science but also for aquaculture. In this article, recent progress in several aspects of puberty in teleosts is reviewed; namely, pubertal changes in brain-pituitary-gonad axis, factors controlling the timing of the onset of puberty, and artificial control of puberty. In addition, possible future directions of study are suggested.
