Special Issue Information
Dear Colleagues,
The process of obtaining high yields in aquaculture is dependent heavily on the use of varieties and strains. While reproduction technology is basic to genetic breeding of aquatic animals, after the breakthrough of artificial fertilization techniques for the four Chinese major carps in 1958–1960, the freshwater fish culture ceased to be limited by the availability of naturally produced seed. Then, selective breeding, cross breeding, gynogenesis and polyploid breeding were applied to fish genetic breeding. Then, the 21st century, great changes in the study of genetic breeding of aquatic animals have been brought by the fast development of molecular biotechnology and bioinformatics. The information of various biological processes regulated at the molecular level, including the discovery of novel loci crucial for population genetics, breeding, and selection, was revealed. Furthermore, for the late decade, high-throughput techniques of the second-generation sequencing (SGS) and third-generation sequencing (TGS) varieties have been widely employed in the genetic breeding of aquatic animals, which promotes the process of whole genome breeding. Today, genetic improvements through new breeding and reproduction technology have been well documented in several farmed aquatic animals, including fish, shrimp, crab and shellfish, etc.
The genetic breeding research of aquatic animals targeting growth and feed efficiency, body shape, immunity and disease resistance, sex determination, stress tolerance, color and pigmentation, intermuscular bone, meat quality, and nutrition, etc., develops and progresses rapidly. So a deep dive into the mechanism of the above biological processes are needed to be further revealed and explained by using of new molecular biology and production technology.
In this Special Issue, publications include original research and reviews in the following fields: reproduction technology; gene function analysis; mapping of genes, traits and QTLs; molecular marker screening and linkage location; associations between genes and traits; genetic diversity; variability at gene and protein levels; the characterization of gene or protein expression and control, related to phenotypic or genetic variation.
We look forward to receiving your contributions.

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).

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
