Resumo: | The objective of this work was to evaluate the tolerance of pirarucu (Arapaima gigas) juveniles to increasing concentrations of ammonia in the water. Eight fish (2.6±0.4 kg and 70.5±4.1 cm length) were evenly distributed in four tanks (0.8x0.9x2.6 m) with 410 L of water buffered with Na2PO4(0.1 M) and HCl (0.1 M), where they were kept for 33 days. Ammonia concentrations in the fish blood plasma and in the water were determined by the salicilate method. Plasma glucose and ammonia levels increased proportionally to the concentration of ammonia in the water. Pirarucu juveniles tolerate high concentrations of ammonia in the water. |

Oito peixes (2,6±0,4 kg e 70,5±4,1 cm de comprimento) foram distribuídos aleatoriamente em quatro tanques (0,8x0,9x2,6 m) com 410 L de água tamponada com Na2PO4 e HCl, ambos a 0,1 M, onde ficaram por 33 dias. As concentrações de amônia no plasma sanguíneo dos peixes e na água foram determinadas pelo método do salicilato. A glicose plasmática e os níveis de amônia aumentaram proporcionalmente à concentração de amônia na água. Juvenis de pirarucu toleram altas concentrações de amônia na água.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCavero, Bruno Adan SagratzkiPereira-Filho, ManoelBordinhon, André Moreirada Fonseca, Flávio Augusto LeãoItuassú, Daniel RabelloRoubach, RodrigoOno, Eduardo Akifumi2004-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6801Pesquisa Agropecuaria Brasileira; v.39, n.5, maio 2004; 513-516Pesquisa Agropecuária Brasileira; v.39, n.5, maio 2004; 513-5161678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6801/3857info:eu-repo/semantics/openAccess2014-07-18T19:22:12Zoai:ojs.seer.sct.embrapa.br:article/6801Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-18T19:22:12Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
