Designing cost-effective fishways is essential for a trade-off between water uses and successful longitudinal connectivity restoration. The multislot fishway (MSF) concept, which operates with 30\u201350% lower discharge than a vertical slot fishway (VSF), was recently developed. This study assessed and compared the entrance performance (entrance time; entry efficiency) and transit times of two cyprinids for VSFs and MSFs. Four configurations, with the same structural characteristics (slope; water depth; head drop; pool width and depth), operating with different discharges (Q), were tested (VSF 1: Q = 112 L\u00b7s\u22121; VSF 2: Q = 80 L\u00b7s\u22121; MSF 1: Q = 58 L\u00b7s\u22121; MSF 2: Q = 37 L\u00b7s\u22121). Hydrodynamics characterization was performed using a numerical model. Results showed that entry efficiency was higher in MSFs than in VSFs, while entrance time and transit time were overall lower. Numerical modelling revealed that velocities were around 30% lower in MSFs, and turbulence could reach a difference of around 70% in Reynolds shear stress and 50% in turbulent kinetic energy. Overall, MSFs can be considered as a cost-effective fishway solution that can balance the trade-offs between divergent interests in water uses.<\/jats:p>","DOI":"10.3390\/w13030275","type":"journal-article","created":{"date-parts":[[2021,1,25]],"date-time":"2021-01-25T12:28:31Z","timestamp":1611577711000},"page":"275","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Multislot Fishway Improves Entrance Performance and Fish Transit Time over Vertical Slots"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3811-775X","authenticated-orcid":false,"given":"Filipe","family":"Rom\u00e3o","sequence":"first","affiliation":[{"name":"CERIS\u2014Civil Engineering for Research and Innovation for Sustainability, T\u00e9cnico, University of Lisbon, Avenida Rovisco Pais, 1049-001 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7854-6850","authenticated-orcid":false,"given":"Ana L.","family":"Quaresma","sequence":"additional","affiliation":[{"name":"CERIS\u2014Civil Engineering for Research and Innovation for Sustainability, T\u00e9cnico, University of Lisbon, Avenida Rovisco Pais, 1049-001 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1232-2560","authenticated-orcid":false,"given":"Jos\u00e9 M.","family":"Santos","sequence":"additional","affiliation":[{"name":"Forest Research Centre, School of Agriculture, University of Lisbon, Tapada da Ajuda, 1349-017 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6573-9154","authenticated-orcid":false,"given":"Susana D.","family":"Amaral","sequence":"additional","affiliation":[{"name":"Forest Research Centre, School of Agriculture, University of Lisbon, Tapada da Ajuda, 1349-017 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2502-5533","authenticated-orcid":false,"given":"Paulo","family":"Branco","sequence":"additional","affiliation":[{"name":"Forest Research Centre, School of Agriculture, University of Lisbon, Tapada da Ajuda, 1349-017 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1423-5391","authenticated-orcid":false,"given":"Ant\u00f3nio N.","family":"Pinheiro","sequence":"additional","affiliation":[{"name":"CERIS\u2014Civil Engineering for Research and Innovation for Sustainability, T\u00e9cnico, University of Lisbon, Avenida Rovisco Pais, 1049-001 Lisboa, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"163","DOI":"10.1017\/S1464793105006950","article-title":"Freshwater biodiversity: Importance, threats, status and conservation challenges","volume":"81","author":"Dudgeon","year":"2006","journal-title":"Biol.
