Special Issue Information
Dear Colleagues,
Sexual determination and reproductive regulation in aquatic organisms, particularly fish species, encompass a diverse array of mechanisms that govern sexual differentiation and reproduction. These processes are pivotal for the survival, growth, and evolution of populations. Gender in fish can be influenced by a complex interplay of genetic, hormonal, and environmental factors, resulting in a spectrum of reproductive strategies ranging from gonochorism to hermaphroditism. Understanding these mechanisms holds significant implications for conservation biology, aquaculture, and fishery management, as they can inform strategies to protect fish populations, enhance productivity, and ensure sustainability.
Recent advancements in technology have significantly accelerated research into sexual determination in aquatic organisms. High-throughput sequencing technologies, such as next-generation sequencing (NGS) and third-generation sequencing (TGS), have transformed the field by enabling researchers to swiftly and accurately identify and analyze the genetic components involved in sex determination. These technologies have facilitated the discovery of sex-linked genes, sex chromosomes, and sex-determining regions in various fish genomes. Furthermore, genome editing techniques like CRISPR/Cas9 have provided unprecedented precision in manipulating genes and studying their roles in sexual differentiation. These technological advancements have deepened our understanding of the genetic architecture underlying sex determination and opened new avenues for exploring the interactions between genetic and environmental factors in shaping sexual fate.
This Special Issue solicits original research articles and comprehensive reviews focusing on sexual determination and reproductive regulation in aquatic organisms. Submissions should emphasize the influence of genetic factors (such as sex chromosomes and key regulatory genes) and environmental factors (including temperature and pollutants) on sexual differentiation, the evolution of sex-determining mechanisms, and their practical applications in breeding programs. Areas of interest encompass sex determination pathways, the evolution of sex chromosomes, the epigenetic regulation of sexual development, and innovative gender control methodologies in aquaculture.
Best regards,
Dr. Liang Guo

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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. Biology is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
