Resumo: The objective of this work was to estimate the sustainable biomass of pirarucu Arapaima gigas (Cuvier, 1829) juveniles kept in small volume net cages. During 200 days four 1-m3 net cages were stocked with 21 fish/cage and had an initial total biomass of 0.84±0.14 kg (21 fish/cage). The net cages were placed in a 50-m2 pond with constant water flow. Conditioning factor, feed conversion, specific growth rate and gain showed that the sustainable biomass of pirarucu juveniles for intensive rearing in 1-m3 net cages was approximately 29 kg. Fish length at the end of the trial, in relation to the reduced net cage space, was a limiting factor to obtain good biological indices.

Durante 200 dias os peixes foram estocados em quatro tanques-rede de 1 m3, cada um com biomassa inicial total de 0,84±0,14 kg (21 peixes/tanque-rede). Os tanques-rede foram colocados em um viveiro de 50 m2 com renovação constante de água. Os índices do fator de condição, da conversão alimentar, do crescimento específico e do ganho de biomassa revelaram que a biomassa sustentável de juvenis de pirarucu para a criação intensiva em tanques-rede de 1 m3 foi de aproximadamente 29 kg. O comprimento alcançado pelo peixe, no espaço reduzido do tanque-rede, é um fator limitante para manter bons índices zootécnicos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCavero, Bruno Adan SagratzkiFilho, Manoel PereiraRoubach, RodrigoItuassú, Daniel RabelloGandra, André LimaCrescêncio, Roger2003-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6629Pesquisa Agropecuaria Brasileira; v.38, n.6, jun. 2003; 723-728Pesquisa Agropecuária Brasileira; v.38, n.6, jun. 2003; 723-7281678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6629/3686info:eu-repo/semantics/openAccess2014-08-11T19:13:01Zoai:ojs.seer.sct.embrapa.br:article/6629Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-11T19:13:01Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
