Special Issue Information
Dear Colleagues,
Freshwater fish play vital ecological roles as seed dispersers, nutrient cyclers, and predators, helping maintain aquatic ecosystem stability. However, in the Anthropocene, human-driven disturbances—such as dam construction, pollution, riparian vegetation loss, and climate change—are increasingly threatening fish populations and their habitats. This Special Issue seeks interdisciplinary research on fish ecology, conservation, and their interactions with changing environments. We welcome studies examining species responses to land-use shifts, emerging stressors (e.g., microplastics, agrochemicals), urbanization effects, and innovative conservation strategies.
Contributions employing ecological modeling, biodiversity assessments, or sustainability frameworks are particularly encouraged. Importantly, we urge authors to propose direct, actionable solutions to mitigate these threats—whether through landscape restoration, policy recommendations, or community engagement. Findings should be communicated in accessible language to aid managers, policymakers, and stakeholders in implementing effective measures, such as designing fish-friendly agricultural systems or fostering public awareness initiatives. By bridging science and practice, this collection aims to inform strategies that safeguard fish communities amid rapid environmental change.

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.
