Special Issue Information

Dear Colleagues,

Shellfish are the second largest group of animals in the world and play a vital role in global aquaculture, significantly contributing to food security and the economy. As global demand for sustainable seafood continues to rise, advancing our understanding of shellfish genetics and breeding is crucial for improving production efficiency and enhancing resilience.

This Special Issue aims to consolidate the latest research on shellfish genetics and breeding, offering new insights and innovative approaches to support sustainable aquaculture. We encourage submissions of original research, comprehensive reviews, and perspectives on various topics, including, but not limited to, the following:

  • Genetic improvement and selection strategies for shellfish species;
  • Advances in molecular tools and techniques for shellfish breeding;
  • Understanding the genetic basis of disease resistance and environmental adaptation in shellfish;
  • The role of genomics in enhancing shellfish breeding programs;
  • Sustainable breeding practices that address climate change impacts.

We look forward to receiving your contributions to this critical and rapidly evolving field.

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.

This study investigates the essential role of the heme cavity in the peroxidase and antibacterial activities of homodimeric hemoglobin (Tg-HbI) from the blood clam Tegillarca granosa. After treatment with sodium dodecyl sulfate (SDS), the peroxidase and antibacterial activities of the Tg-HbI were significantly inhibited, with the degree of inhibition correlating positively with the SDS concentration. Fluorescence spectroscopy, UV-Vis spectroscopy, and molecular docking analysis further revealed that SDS interacts with key amino acid residues (e.g., His70 and His102) in the heme cavity of Tg-HbI, causing conformational changes that disrupt the internal hydrophobic interactions, thus inhibiting its function. This study confirms that the antibacterial effect of Tg-HbI is mediated through its peroxidase activity and that the heme cavity plays a critical role in maintaining this activity. These findings lay a foundation for further research on the immune defense functions of hemoglobin and provide new insights into the mechanisms of environmental adaptation in T. granosa. Full article

The blood clam (Anadara granosa) is an economic bivalve that is relatively tolerant to hypoxia, but its molecular mechanism of hypoxia tolerance is unclear. We found that a significant decrease in extracellular Ca2+ concentration and a marked increase in intracellular Ca2+ concentration was observed in the blood clam through the fluorescence probe method, under hypoxic conditions at 0.5 mg/L. Concomitantly, there was a downward trend in the expression level of CaV2 mRNA, whereas NFAT (nuclear factor of activated T cells) expression increased by qRT-PCR. These findings suggest that the elevated intracellular Ca2+ concentration may activate negative transcription factors of NFAT, which subsequently suppresses the transcription of CaV2, leading to its decreased expression. Then, the NFAT RNA interference experiments supported this hypothesis. Sequence analysis and 3D structure prediction revealed conserved and mutated residue sites in blood clam compared to other bivalves. Hypoxia-induced changes in intracellular and extracellular Ca2+ concentrations, activating transcription factor NFAT and suppressing CaV2 expression. This study highlights the key roles of CaV2 and NFAT in hypoxia adaptation, paving the way for further exploration of hypoxia tolerance mechanisms in mollusca. Full article
