A qualitative and semi\u2010quantitative histological approach was performed in specimens from 2007 and 2019. Prevalence and mean intensity of parasites and histopathological changes were calculated in both years. No macroscopic alterations were found in any organ but several parasites (e.g., copepods, nematodes, digeneans) were detected. Microscopically, alterations identified in gills included foci of inflammation and hyperplasia (present in 77.38% of hakes from both years), extensive hyperplasia (33.33%), and inflammation (16.65%) that were potentially related to the mechanical effects of monogeneans and copepods, cysts of unknown etiology (62.69%), and lamellar inflammation associated to <jats:italic>Aporocotyle spinosicanalis<\/jats:italic> eggs (8.33%). Granulomas and inflammatory focus were detected in the liver, spleen, and stomach, apparently associated with the presence of nematodes. Coelozoic myxosporean parasites were detected within the renal tubules (66.66%). Most of the pathologies detected were similar to those described in other gadoid species (i.e., <jats:italic>Gadus morhua<\/jats:italic>) and were usually related to the presence of ecto and endoparasites. The potential impact of parasites on the health of this fish species is discussed for improving the knowledge and management of these valuable fishing stocks.<\/jats:p>","DOI":"10.1111\/jfb.15940","type":"journal-article","created":{"date-parts":[[2024,9,20]],"date-time":"2024-09-20T03:13:49Z","timestamp":1726802029000},"page":"1906-1918","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Diving into the fish pathology of an important commercial fish species: the case of the European hake (<i>Merluccius merluccius<\/i> Linnaeus, 1758) in the northwest Mediterranean Sea"],"prefix":"10.1111","volume":"105","author":[{"given":"Laura","family":"Muns\u2010Pujadas","sequence":"first","affiliation":[{"name":"Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia Universitat Aut\u00f2noma de Barcelona  Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7672-123X","authenticated-orcid":false,"given":"Maria","family":"Constenla","sequence":"additional","affiliation":[{"name":"Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia Universitat Aut\u00f2noma de Barcelona  Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sara","family":"Dallar\u00e9s","sequence":"additional","affiliation":[{"name":"Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia Universitat Aut\u00f2noma de Barcelona  Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesc","family":"Padr\u00f3s","sequence":"additional","affiliation":[{"name":"Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia Universitat Aut\u00f2noma de Barcelona  Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,9,19]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2761.2001.00298.x"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/jfd.13776"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/jfb.12362"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.3354\/dao075159"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2761.1999.00134.x"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2761.2010.01226.x"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.15244\/pjoes\/60326"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.icesjms.2005.10.009"},{"key":"e_1_2_9_10_1","volume-title":"Potential pathological effects of blood flukes (Digenea: Sanguinicolidae) on pen\u2010reared marine fishes","author":"Bullard S.","year":"2002"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.2307\/3284227"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.3390\/jmse9040389"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fishres.2019.105333"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijpara.2019.04.004"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.marpolbul.2012.06.008"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.marpolbul.2022.113441"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1139\/cjfas-2020-0315"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/9781444392210.ch10"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.dsr.2015.07.002"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11356-021-16408-7"},{"key":"e_1_2_9_21_1","first-page":"292","volume-title":"The handbook of histopathological practices in aquatic environments: Guide to histology for environmental toxicology","author":"Costa P.
