Special Issue Information
Dear Colleagues,
The habitats and swimming behavior of river fish are influenced by a combination of hydrodynamic conditions, morphological traits, and human activities. At river confluences, complex flow patterns affect the migration of fish, challenging their ability to maintain their position and avoid predation. Ecohydraulic models, as discussed in recent studies, are valuable tools for assessing the suitability of these habitats, particularly in sinuous bends and multi-thread river sections, where the flow multiplicity and velocity gradients vary substantially. These models support ecological conservation by identifying essential habitat features that meet the diverse requirements of different fish species.
The swimming behavior of fish varies with river flow conditions and is influenced by their body morphology and tail-beat frequency, which play crucial roles in energy conservation and mobility. Morphologically adapted fish species can navigate varying water depths, flow velocities, and sediment loads, supporting their survival in distinct river sections. These insights help optimize habitat design and restoration efforts, ensuring that river modifications, such as dam construction, incorporate fish-friendly structures to preserve the ecological continuity and minimize the disruption to natural swimming patterns.

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.
