Special Issue Information

Dear Colleagues,

The strategic cultivation of high-quality varieties is critically important for the sustainable and efficient progression of the aquaculture sector. A thorough understanding of the developmental processes associated with the economic characteristics of aquaculture organisms is essential. Such knowledge enhances our grasp of the molecular mechanisms governing these traits, providing a solid scientific basis for their genetic enhancement. The rapid evolution of molecular biology techniques, notably advanced transgenic and gene editing methodologies, coupled with high-throughput sequencing, has substantially enriched our understanding of the genetic underpinnings of aquaculture species. Concurrently, this has streamlined and optimized the investigation of genes implicated in the development of economically significant traits.

While traditional breeding techniques, including individual selection, family selection, and hybrid breeding, retain their value due to their simplicity and operational feasibility, novel and emergent breeding technologies such as genome-wide selection, precision molecular-assisted breeding, and modular breeding approaches offer more precise and efficient avenues for genetic improvement. These cutting-edge techniques signify a forward-moving trend in the development of new, high-yield aquaculture breeds. This Special Issue is dedicated to exploring the molecular mechanisms involved in the formation of economic traits in aquaculture animals and delves into the latest research on efficient genetic breeding strategies.

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. Fishes 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 2600 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.

Hong Kong oysters (Crassostrea hongkongensis) are an important marine bivalve with nutritional and commercial value. The expanded off-bottom farming scale in recent years makes the oysters more susceptible to exposure to abiotic stresses, such as salinity stress, an important environmental factor that has been proven to have significant effects on oyster growth and development. However, the molecular mechanism is still unclear. Cyclin E is an important protein in the process of cell cycle regulation that is indispensable for propelling G1/S phase transition in a dose-dependent manner. In order to investigate whether the salinity stress affects cyclin E expression in oysters, the cDNA sequence of C. hongkongensis cyclin E (Ch-CCNE) was isolated from a gill cDNA library, and the 2.8 kbp length cDNA fragment contained a complete open reading frame (ORF) encoding 440 amino acid residues. Ch-CCNE mRNA was highly expressed in the gonad and low in the adductor mussel, mantle, gill, labial palp, and digestive gland. The recombinant CCNE protein was expressed and purified in a pET32a(+)-CCNE/Escherichia coli BL21(DE3) system via IPTG induction and was used for generating mice anti-Ch-CCNE antiserums. Western blot analysis showed that the CCNE protein in the gill was maintained at low expression levels under either hypo- (5 ppt) or hyper- (35 ppt) salinity, and could be produced at high levels under appropriate salinity during a 10-day exposure period. The immuno-localization indicated that the Ch-CCNE protein was distributed in the nucleus. These results suggested that either hypo- or hyper-salinity stress could inhibit the CCNE expression of Hong Kong oysters and their negative impact on cell division and proliferation. Full article
