Resumo: The objective of this work was to evaluate the growth and the stress levels of juvenile dourado (Salminus brasiliensis) cultivated in cages. Fish stocked at densities of 15 (D15) and 30 (D30) fish per square meter were evaluated in a completely randomized design with three replicates. Fish were fed twice a day with extruded ration (42% crude protein). Density influenced only biomass and daily food intake, and glucose and lactate concentrations increased over time. D15 and D30 did not influence the growth of dourado. However, the increase of glucose and lactate levels over time indicates that cultivation in cages is a stressful condition for this species.

Peixes estocados nas densidades de 15 (D15) e 30 (D30) peixes por metro quadrado foram avaliados em delineamento inteiramente casualizado, com três repetições. Os peixes foram alimentados duas vezes ao dia com ração extrusada (42% de proteína bruta). A densidade influenciou apenas a biomassa e a ingestão diária, e as concentrações de glicose e lactato aumentaram ao longo do tempo. D15 e D30 não influenciaram o crescimento do dourado. No entanto, o aumento dos níveis de glicose e de lactato ao longo do tempo indica que o cultivo em tanques‑rede é uma condição estressante para esta espécie.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCAPESBraun, NeivaDafre, Alcir LuizLima, Ronaldo Lima deBeux, Luis FernandoBrol, Fernanda FrancieleNuñer, Alex Pires de Oliveira2013-10-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/11429Pesquisa Agropecuaria Brasileira; v.48, n.8, ago. 2013: Número Temático Aquacultura; 1145-1149Pesquisa Agropecuária Brasileira; v.48, n.8, ago. 2013: Número Temático Aquacultura; 1145-11491678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/11429/12365https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/11429/6947https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/11429/6948info:eu-repo/semantics/openAccess2013-11-11T13:34:21Zoai:ojs.seer.sct.embrapa.br:article/11429Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-11-11T13:34:21Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
