Special Issue Information

Dear Colleagues,

The living fish species (including bony fish, cartilaginous fish, and jawless fish) encompass the great majority of non-tetrapod vertebrates, and serve as an important clade of highly commercial, ecological, evolutionary, and conservation significance. Marine fishes play crucial ecological roles in marine ecosystems, contributing to high levels of biodiversity; they are also a major source of protein for human populations and support economies and important social structures in many nations. However, overfishing, global warming, and habitat loss contribute drastically to large-scale population declines of marine fish species. It is therefore imperative to understand these species for sound management and conservation of marine fish resources. Genetic and genomic investigations can largely deepen our knowledge on species diversity, adaptation, and evolution, thus facilitating effective fishery management and biodiversity conservation. However, limited genetic and genomic resources of marine fish species have been reported until now, so I am pleased to invite you to contribute to the Special Issue “Molecular Genetics and Genomics of Marine Fishes” in the Fishes journal.

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.

To better understand the population genetic structure and molecular biological background of Conger myriaster, an economically important marine fish, a total of 217 complete mitochondrial cytochrome b (Cyt b) gene sequences with a length of 1142 bp were obtained to assess the genetic diversity, population differentiation, and demographic history of seven populations along the coastal waters of China. The analysis of population genetic diversity showed a high level of haplotype diversity and a low level of nucleotide diversity. The analysis of molecular variance (AMOVA) and the genetic differentiation coefficient (FST) showed that most of the variation came from within populations, and the geographic distribution of haplotypes revealed non-significant genetic differentiation among populations. Tracing the population dynamic history, the results of the neutrality test and mismatch analysis suggested that the populations of C. myriaster in coastal China seas had experienced demographic expansion, and the expansion time can be traced back to the middle Pleistocene period. These results provide supplemental information for the sustainable utilization of fishery resources of this species. Full article
