Based on the characteristic radiographic findings, we here present a vertebral column deformity named \u201ccurved cross\u2010stitch vertebrae\u201d that mainly affects the middle aspect of the vertebral column. Sixty fish, from the west\/northwest coast of mid\u2010Norway, were sampled at slaughter and examined by radiography, computed tomography (CT), necropsy, macrophotography, and histology. The vertebral deformities were radiographically graded as mild, moderate, or marked. The main differences between these grades of changes were defined by increased curving of the peripheries of endplates, reduced intervertebral spaces, and vertical displacement of the vertebrae. The curved rims of endplates were located peripheral to a continuous and approximately circular borderline. The CT studies revealed small, multifocal, hypo\u2010attenuating, round to crescent\u2010shaped areas in the notochord, compatible with the presence of gas. Additionally, histology revealed that the axial parts of endplates had circular zones with perforations, through which either notochordal tissue prolapsed into the vertebrae or vascularized fibrochondroid proliferations extended from the vertebrae into the notochord. Inflammation was present in many vertebral bodies. To the best of our knowledge, this is the first report of gas in the notochord of fish.<\/jats:p>","DOI":"10.1111\/jfd.13136","type":"journal-article","created":{"date-parts":[[2020,1,23]],"date-time":"2020-01-23T03:12:30Z","timestamp":1579749150000},"page":"379-389","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Vertebral column deformity with curved cross\u2010stitch vertebrae in Norwegian seawater\u2010farmed Atlantic salmon, <i>Salmo salar<\/i> L."],"prefix":"10.1111","volume":"43","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3767-5514","authenticated-orcid":false,"given":"Cathrine","family":"Trangerud","sequence":"first","affiliation":[{"name":"Department of Companion Animal Clinical Sciences, Faculty of Veterinary Medicine Norwegian University of Life Sciences Oslo Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H\u00e5vard","family":"Bj\u00f8rgen","sequence":"additional","affiliation":[{"name":"Section of Anatomy, Faculty of Veterinary Medicine Norwegian University of Life Sciences Oslo Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4859-1455","authenticated-orcid":false,"given":"Erling Olaf","family":"Koppang","sequence":"additional","affiliation":[{"name":"Section of Anatomy, Faculty of Veterinary Medicine Norwegian University of Life Sciences Oslo Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Randi Nygaard","family":"Gr\u00f8ntvedt","sequence":"additional","affiliation":[{"name":"INAQ AS Trondheim Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hege Kippenes","family":"Skogmo","sequence":"additional","affiliation":[{"name":"Department of Companion Animal Clinical Sciences, Faculty of Veterinary Medicine Norwegian University of Life Sciences Oslo Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nina","family":"Ottesen","sequence":"additional","affiliation":[{"name":"Department of Companion Animal Clinical Sciences, Faculty of Veterinary Medicine Norwegian University of Life Sciences Oslo Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agnar","family":"Kvellestad","sequence":"additional","affiliation":[{"name":"Section of Anatomy, Faculty of Veterinary Medicine Norwegian University of Life Sciences Oslo Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,1,22]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1155\/2018\/1574020"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2761.2007.00899.x"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prevetmed.2009.03.015"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/raq.12255"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2095.1998.00095.x"},{"key":"e_1_2_9_7_1","volume-title":"Theory and practice of histological techniques","author":"Bancroft J.
