In this study, we evaluated the influence of different genetic markers (COI, 12S rRNA, and 16S rRNA) and water sample volumes (0.5, 1.0, 2.5, 5.0, and 10\u2009L) on eDNA-based detection of 60 marine fish species maintained at the Ocean\u00e1rio de Lisboa. Five primer sets were used to generate amplicon libraries from triplicate water samples per tested volume. Overall, the combined use of all markers enabled the detection of 81.7% of the fish species present in the tank ( n\u00a0=\u00a049), as well as 37 additional exogenous taxa. Detection success varied among primer sets, ranging from 31.7% for COI FishATL_Cocktail1 to 73.3% for Fish16S. When accounting for reference sequence availability, relative detection success reached 82.4% for 12S and 77.2% for 16S. Increasing water volume consistently led to higher species detection across all markers, with detection percentages approaching saturation at the highest volumes tested. When pooling all markers, up to 76.7% of the species present were detected using a water volume of 5\u2009L. These results highlight the limitations of relying on a single genetic marker and demonstrate the strong influence of sampling volume on detection efficiency, a factor likely to be even more critical in open marine environments.<\/jats:p>","DOI":"10.1139\/gen-2026-0026","type":"journal-article","created":{"date-parts":[[2026,9,27]],"date-time":"2026-09-27T21:34:47Z","timestamp":1790544887000},"page":"1-16","update-policy":"https:\/\/doi.org\/10.1139\/csp-crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Environmental DNA for detecting marine fish species: testing the volume of sampled water, markers, and primers in a public oceanarium"],"prefix":"10.1139","volume":"69","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5267-9674","authenticated-orcid":false,"given":"Andr\u00e9 O.","family":"Ferreira","sequence":"first","affiliation":[{"name":"University of Minho \u2013 Campus de Gualtar","place":["Braga, Portugal"]},{"name":"University of Minho \u2013 Campus de Gualtar","place":["Braga, Portugal"]},{"name":"University of Porto, Terminal de Cruzeiros do Porto de Leix\u00f5es","place":["Matosinhos, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cl\u00e1udia","family":"Machado","sequence":"additional","affiliation":[{"name":"University of Minho \u2013 Campus de Gualtar","place":["Braga, Portugal"]},{"name":"University of Minho \u2013 Campus de Gualtar","place":["Braga, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Barroso","sequence":"additional","affiliation":[{"name":"University of Coimbra","place":["Coimbra, Portugal"]},{"name":"Biocant \u2013 Transfer Technology Association","place":["Cantanhede, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N\u00faria","family":"Baylina","sequence":"additional","affiliation":[{"name":"Ocean\u00e1rio de Lisboa","place":["Lisboa, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Concei\u00e7\u00e3o","family":"Egas","sequence":"additional","affiliation":[{"name":"University of Coimbra","place":["Coimbra, Portugal"]},{"name":"Biocant \u2013 Transfer Technology Association","place":["Cantanhede, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jo\u00e3o T.","family":"Fontes","sequence":"additional","affiliation":[{"name":"University of Minho \u2013 Campus de Gualtar","place":["Braga, Portugal"]},{"name":"University of Minho \u2013 Campus de Gualtar","place":["Braga, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margarida","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Ocean\u00e1rio de Lisboa","place":["Lisboa, Portugal"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Oliveira","sequence":"additional","affiliation":[{"name":"S\u00e3o Paulo State University","place":["S\u00e3o Paulo, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
