To better understand health issues associated with the care of these species in public aquaria, reports from all necropsies performed in 2 zoological institutions between 2009 and 2019 were reviewed (31 AW and 8 SW). These wolffish were fed with a similar fish-based diet and kept in multi-species exhibits with comparable environmental parameters. The most frequent necropsy findings were the presence of xanthomas (AW: 41.9%; SW: 75.0%), nephrocalcinosis (AW: 42.9%; SW: 75.0%) and urocystoliths (AW: 6.5%; SW: 62.5%). Xanthomas were mostly located at the base of pectoral fins and were characterized by extensive granulomatous inflammation centered on accumulations of partly mineralized degenerate fatty material, mainly composed of cholesterol crystals. Nephrocalcinosis was characterized by the deposition of calcium salts within the renal tubules and was commonly associated with tubular necrosis. The aquarium-housed wolffish were fed a coldwater fish-based diet. However, the natural diet of wolffish is composed mostly of invertebrates such as urchins and crustaceans. Differences in nutrient composition between these diets, such as lipid and mineral content, may have contributed to the development of xanthomatosis, nephrocalcinosis and urocystolithiasis in wolffish housed in these institutions.<\/jats:p>","DOI":"10.3354\/dao03477","type":"journal-article","created":{"date-parts":[[2020,3,31]],"date-time":"2020-03-31T21:06:16Z","timestamp":1585688776000},"page":"223-232","source":"Crossref","is-referenced-by-count":12,"title":["High occurrence rate of xanthomatosis and nephrocalcinosis in aquarium-housed Atlantic wolffish Anarhichas lupus and spotted wolffish A. minor"],"prefix":"10.3354","volume":"139","author":[{"given":"K","family":"B\u00e9land","sequence":"first","affiliation":[{"name":"Centre qu\u00e9b\u00e9cois sur la sant\u00e9 des animaux sauvages\/Canadian Wildlife Health Cooperative, Facult\u00e9 de m\u00e9decine v\u00e9t\u00e9rinaire, Universit\u00e9 de Montr\u00e9al, St. Hyacinthe, Quebec J2S 8H5, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E","family":"Wong","sequence":"additional","affiliation":[{"name":"Biod\u00f4me de Montr\u00e9al, Montreal, Quebec H1V 1B3, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JF","family":"St-Cyr","sequence":"additional","affiliation":[{"name":"S\u00e9paq, Aquarium du Qu\u00e9bec, Quebec City, Quebec G1W 4S3, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Lair","sequence":"additional","affiliation":[{"name":"Centre qu\u00e9b\u00e9cois sur la sant\u00e9 des animaux sauvages\/Canadian Wildlife Health Cooperative, Facult\u00e9 de m\u00e9decine v\u00e9t\u00e9rinaire, Universit\u00e9 de Montr\u00e9al, St. Hyacinthe, Quebec J2S 8H5, Canada"},{"name":"S\u00e9paq, Aquarium du Qu\u00e9bec, Quebec City, Quebec G1W 4S3, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1913","reference":[{"key":"Ref1","doi-asserted-by":"publisher","DOI":"10.1080\/01652176.2015.1123823"},{"key":"Ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cvsm.2015.03.001"},{"key":"Ref3","doi-asserted-by":"publisher","DOI":"10.1577\/1548-8667(2001)013<0368:NINTFA>2.0.CO;2"},{"key":"Ref4","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2761.2012.01396.x"},{"key":"Ref5","unstructured":"COSEWIC (Committee on the Status of Endangered Wildlife in Canada) (2012) COSEWIC assessment and status report on the Atlantic wolffish Anarhichas lupus in Canada.
