Special Issue Information

Dear Colleagues,

Fishing gears vary greatly in their capture principles, configurations, and materials used for different types of gears. Fisheries worldwide are using diverse range of different methods for capturing fish, shellfish, and other organisms. The choice of the fishing gear affects its catchability or fishing efficiency, as well as gear operations depending on the fishing area and targeted species. Furthermore, it also affects environmental impact caused by fisheries through bycatch, seabed impact, marine pollution, and other negative effects caused by abandoned, lost, or otherwise discarded fishing gear, among other issues.

This Special Issue aims at summarizing research results including, but not limited to, the following:

  • Fishing gear catch efficiency and species and size selectivity;
  • Environmental impact caused by fishing activities (for example, seabed impact and carbon footprint);
  • Fisheries impacts on biodiversity;
  • Marine pollution caused by fishing activities;
  • Challenges caused by abandoned, lost, or otherwise discarded fishing gear, such as continuous capture of marine animals by such gear (“ghost fishing”);
  • Other innovations in fishing gear technology that can improve the efficiency and environmental sustainability of fisheries.

Submissions may take the form of original research, systematic reviews, or short communications.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

We sought to develop and evaluate an escape vent designed for undersized swimming crabs (Portunus trituberculatus) to reduce bycatch, contributing to the preservation of marine resources. To this end, we conducted aquarium experiments and selectivity analysis to determine the appropriate size of the escape vent that would allow only undersized crabs with a carapace length of 64 mm or less to escape. The optimal dimensions for the escape vent were approximately 34.1 mm in height and 69.1 mm in width. During the sea trial, the average bycatch rates for undersized crabs per pot were 57.2%, 15.0%, and 22.3% for the control, basic, and door types, respectively. Regarding legal-sized crab catch per pot, averages of 1.40, 1.72, and 1.62 individuals were obtained for the three pot types. To our knowledge, this study is the first to assess the optimal size for an escape vent capable of reducing the bycatch of undersized crabs while maintaining legal-sized swimming crabs capture.

This study evaluated the carbon emissions as one of the environmental impacts of fishing activities in China during the period of 2010–2022. The decoupling effect of fishery carbon emissions and fishery economic growth was analyzed using a decoupling model. The findings reveal that China’s fishery carbon emissions are substantial and exhibit multi-stage variations. Inland areas mainly emit carbon from aquatic feed decomposition and aquaculture equipment electricity consumption, with differing structures between high- and low-emission regions. Coastal areas primarily emit carbon from fishing, supplemented by aquatic feed. From 2010 to 2011, decoupling was poorly idealized as strong negative decoupling, but post-2011 featured mainly weak decoupling with strong decoupling as a complement. After excluding economic factors, carbon intensity and population size positively influenced decoupling, with intensity initially leading and scale later expanding. Structural factors mainly hindered decoupling. Full article
