Special Issue Information
Dear Colleagues,
Puberty can be defined as the process by which an immature animal acquires the ability to reproduce for the first time. In fish, puberty it is characterized by the beginning of gametogenesis and it is controlled by the activation of the brain-pituitary-gonad axis. This axis stimulates the synthesis and secretion of follicle stimulating hormone and luteinizing hormone, which in turn act on the gonads controlling the production of germ cells (gametogenesis) and sex steroids (steroidogenesis). Age and size at puberty is species-specific and different internal and external factors stimulate and modulate this activation. However, in fish, the information about the regulation of the early stages of gametogenesis is limited. In addition, onset of puberty is a major problem in aquaculture due to its negative influence on growth, feed conversion, health or animal welfare as well as on species diversification. A thorough study of these early stages becomes thus essential in order to find solutions to current and pressing issues in aquaculture.
This Special issue aims to generate knowledge on endocrine, paracrine, and autocrine mechanisms involved in the regulation of the initial stages of gametogenesis and the onset of puberty in male and female fish.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page.
