However, parasitic infestations have emerged as a significant factor influencing fish aquaculture production, negatively impacting the profitability of this food production activity. This study aimed to report the mutilation of pirapitinga Piaractus brachypomus gill filaments caused by a Cymothoidae parasite. In April 2022, Piaractus brachypomus were examined at a fish farm in Macap\u00e1, state of Amap\u00e1, Brazil. The host fish were analyzed, and the parasite found was preserved in 70% ethyl alcohol for taxonomic identification. Of the 31 fish examined, one had its gills infested with a crustacean parasite identified as Braga patagonica. A female parasite caused macroscopic mutilation of the filaments on the four right gill arches of P. brachypomus and severe damage at the attachment site. This is the first record of B. patagonica infestation in P. brachypomus. The fish farming water supply allowed the isopod ectoparasite to pass from wild fish to the pond, where it consequently found favorable conditions in the host fish.<\/jats:p>","DOI":"10.1590\/s1984-29612025068","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T15:08:26Z","timestamp":1765206506000},"source":"Crossref","is-referenced-by-count":1,"title":["Mutilation on gill filaments of Piaractus brachypomus (Characiformes: Serrasalmidae) caused by Braga patagonica (Crustacea: Cymothoidae), in the Brazilian Amazon"],"prefix":"10.1590","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4421-9608","authenticated-orcid":false,"given":"Marcos Sidney Brito","family":"Oliveira","sequence":"first","affiliation":[{"name":"Universidade do Estado do Amap\u00e1,  Brasil; Universidade Federal do Amap\u00e1,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8376-1846","authenticated-orcid":false,"given":"Marcos","family":"Tavares-Dias","sequence":"additional","affiliation":[{"name":"Universidade Federal do Amap\u00e1,  Brasil; Empresa Brasileira de Pesquisa Agropecu\u00e1ria,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2025]]},"reference":[{"issue":"1","key":"ref1","doi-asserted-by":"crossref","first-page":"330","DOI":"10.1186\/s12917-022-03405-2","article-title":"Livoneca redmanii Leach, 1818 (Cymothoidae) a parasitic isopod infesting the gills of the European seabass, Dicentrarchus labrax (Linnaeus, 1758): morphological and molecular characterization study","volume":"18","author":"Abdallah ESH","year":"2022","journal-title":"BMC Vet Res"},{"key":"ref2","series-title":"Animal biodiversity: an outline of higher-level classification and survey of taxonomic richness","first-page":"165","volume-title":"Subphylum Crustacea Br\u00fcnnich, 1772","author":"Ahyong ST","year":"2011"},{"issue":"1","key":"ref3","doi-asserted-by":"crossref","first-page":"57","DOI":"10.1016\/j.ejar.2018.03.001","article-title":"Histopathological alterations and condition factor deterioration accompanied by isopod infestation in Tilapia zilli, Mugil capito and Solea aegyptiaca from Lake Qaroun","volume":"44","author":"Ali NG","year":"2018","journal-title":"Egypt J Aquat Res"},{"key":"ref4","doi-asserted-by":"crossref","DOI":"10.1590\/2358-2936e20240530","article-title":"Isopod parasites of Pygocentrus piraya (Characiformes: Serrasalmidae) in the lower S\u00e3o Francisco River, Brazil","volume":"32","author":"Alves AM","year":"2024","journal-title":"Nauplius"},{"issue":"3","key":"ref5","doi-asserted-by":"crossref","first-page":"813","DOI":"10.2307\/1444352","article-title":"Tongue replacement in a marine fish (Lutjanus guttatus) by a parasitic isopod (Crustacea: isopoda)","volume":"1983","author":"Brusca RC","year":"1983","journal-title":"Copeia"},{"key":"ref6","first-page":"1","article-title":"Studies on the cymothoid fish symbionts of the Eastern Pacific (Crustacea: Isopoda: Cymothoidae).
