Special Issue Information

Dear Colleagues,

This Special Issue is an important platform to promote the development of world aquatic science research, strengthen international academic exchanges, and showcase the latest scientific research achievements and progress in the field of aquatic science in different countries.

It will mainly publish papers and reviews on aquatic animal breeding research, aquaculture and breeding, aquaculture breeding technology development, fishery resources, fishery water environment protection, etc.

This Special Issue accepts theoretical and empirical research papers, particularly encouraging the combination of theory and empirical research. The published research results can represent the academic level and development trends in relation to aquaculture, reflecting new achievements and ideas in the research of aquaculture breeding technology worldwide.

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. Animals is an international peer-reviewed open access semimonthly 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 2400 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.

The marine gastropod Semicassis bisulcatum, valued for its ornamental shell and edible soft tissue, lacks essential biological data for selective breeding. This study was conducted on 100 wild individuals collected from the Beibu Gulf to identify key morphological traits influencing body mass (BM) and soft body mass (SBM). Both mass traits showed high variability (SBM CV = 41.04%; BM CV = 23.88%), indicating strong breeding potential. Path analysis revealed that shell thickness (ST) exhibited the strongest direct association with body mass (path coefficient = 0.509), while shell width (SW) was most closely linked to soft body mass (path coefficient = 0.482). The combined coefficient of determination confirmed that shell thickness (ST) and shell height (SH) together were the strongest predictors for body mass. Similarly, Shell width (SW) and aperture height (AH) together had the strongest combined effect on soft body mass. These findings provide a critical morphological basis for future selective breeding programs. Full article

Artificial gynogenesis is an effective means of producing pure lines and is widely used for genetic analysis of fish and for sex control. In this study, inactivated sperm from heterogenous blunt snout bream (Megalobrama amblycephala, MA) were used to activate Kohaku koi (Cyprinus carpio var. koi, CK) and produce high-quality female offspring. To determine whether the offspring were gynogenetic fish, the karyotype and DNA content of the CK, MA and the induced offspring (IO) were first compared and it was found that the IO were diploid with 100 chromosomes and their karyotype was 22m + 34sm + 22st + 22t. The DNA content of the IO was not significantly different from that of the CK. Subsequently, the amplified band profiles of CK, MA and IO were analyzed with species-specific microsatellite markers. The results showed that there were no amplified MA microsatellite bands in IO. The size of the amplified bands and the sequence of the 5S rDNA in CK, MA and IO were also analyzed. It was found that the amplified 5S rDNA gene fragments in IO contained two fragments that were both the same size as those of CK and matched more than 90% with those of CK. Finally, the sex of IO was verified using gonadal tissue sections. The result showed that IO was not an all-female population; males were also present (36.7%). In summary, a series of validation methods confirmed that the induced offspring were gynogenetic fish, which is the basis for the subsequent genetic improvement of pure lines of high-quality koi.
