Special Issue Information

Dear Colleagues,

Catfish is a common name for a diverse group of fish that belong to the order Siluriformes, which comprise over 2200 species. Catfish are renowned for their adaptability, thriving in various aquatic environments from freshwater rivers to brackish swamps. Therefore, catfish farming is popular in China, the United States, and Southeast Asian and African countries. Global production of catfish is 6.62 million tonnes, which is the second largest species group of finfish. Additionally, catfish are also popular game fish and aquarium fish. Information on catfish biology, hatchery and nursery technology, grow-out models, disease control, transportation, and processing has been studied, which has significantly promoted the catfish industry.

This Special Issue focuses on different aspects of catfish research that could provide a basic reference for catfish aquaculture. We welcome manuscripts covering, but not limited to, genetic improvement and breeding, physiology and biochemistries, nutrition and aquaculture feed, disease prevention and control, immunity, and ecological farming technologies related to catfish. The goal of this Special Issue is to gather creative ideas and highlight novel findings that can contribute to catfish research and aquaculture.

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 250 words) can be sent to the Editorial Office for assessment.

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.

To elucidate the temporal dynamics of genetic diversity across successive breeding generations of channel catfish (Ictalurus punctatus) and enhance subsequent breeding efficiency, we systematically evaluated the genetic variation in four consecutive generations using ten highly polymorphic microsatellite loci. The number of alleles (Na), effective alleles (Ne), and Shannon’s index (I) all declined with increasing generations. The mean expected heterozygosity (He) decreased gradually from 0.822 to 0.805 but remained above 0.80, indicating that all generations maintained relatively high genetic diversity. Allele frequency analysis revealed the progressive fixation of alleles potentially linked to target traits, while some rare alleles were gradually lost. Analysis of molecular variance (AMOVA) demonstrated that 98% of the genetic variation occurred within generations, with weak differentiation among generations (Fst = 0.016). UPGMA clustering further indicated that later generations diverged from the base stock, whereas genetic distances among adjacent generations progressively narrowed, suggesting increasing convergence and stabilization of genetic structure. These findings provide both theoretical insights and practical guidance for the continuous selective breeding and germplasm conservation of channel catfish. Full article
