In the present study, two strobe light frequencies, 350 flashes\/minute and 600 flashes\/minute, were tested in laboratorial conditions, using three native freshwater fish species of northern Portugal: Brown trout (Salmo trutta), Northern straight-mouth nase (Pseudochondrostoma duriense) and Iberian barbel (Luciobarbus bocagei). The results showed a differential repulsive behavior of the fish species to light stimulus, and particularly to a frequency of 600 flashes\/minute. S. trutta presented the most repulsive behavior, whereas the L. bocagei showed less repulsion to the light stimulus. No relevant differences were found between pre-test and post-assessments, confirming a rapid recovery of natural fish behavior after the deterrent effect. The results highlighted the potential of behavioral barriers, particularly in salmonid streams, based on strobe light stimulus.<\/jats:p>","DOI":"10.3390\/su11051332","type":"journal-article","created":{"date-parts":[[2019,3,4]],"date-time":"2019-03-04T05:22:26Z","timestamp":1551676946000},"page":"1332","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Repulsive Effect of Stroboscopic Light Barriers on Native Salmonid (Salmo trutta) and Cyprinid (Pseudochondrostoma duriense and Luciobarbus bocagei) Species of Iberia"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3234-7554","authenticated-orcid":false,"given":"Joaquim","family":"Jesus","sequence":"first","affiliation":[{"name":"CITAB, Centre for the Research and Tecnhology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Quinta dos Prados, 5000-911 Vila-Real, Portugal"},{"name":"OriginAL Solutions, Estrada do Cando, Casa da Fraga, 5400-010 Chaves, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5336-1174","authenticated-orcid":false,"given":"Am\u00edlcar","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Centro de Investiga\u00e7\u00e3o de Montanha (CIMO), Instituto Polit\u00e9cnico de Bragan\u00e7a, Campus de Santa Apol\u00f3nia, 5300-253 Bragan\u00e7a, Portugal"}]},{"given":"Silvestre","family":"Nat\u00e1rio","sequence":"additional","affiliation":[{"name":"OriginAL Solutions, Estrada do Cando, Casa da Fraga, 5400-010 Chaves, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8602-7663","authenticated-orcid":false,"given":"Rui","family":"Cortes","sequence":"additional","affiliation":[{"name":"CITAB, Centre for the Research and Tecnhology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes e Alto Douro, Quinta dos Prados, 5000-911 Vila-Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"244","DOI":"10.1071\/MF09300","article-title":"Threatening processes and conservation management of endemic freshwater fish in the Mediterranean basin: A review","volume":"62","author":"Hermoso","year":"2011","journal-title":"Mar.
