Resumo: | The objectives of this study were to evaluate the efficiency of salt as a stress reductor and to determine the best transportation density for tambaqui (Colossoma macropomum) juveniles in customized plastic boxes. In the first experiment different concentrations of cooking salt (NaCl) in the water were tested, and in the second experiment the fishes were transported for three hours in 200 L plastic boxes using different fish densities and 8 g of salt/L of water. Plasma cortisol presented a significant increase after transportation in water without salt or with 2 g of salt/L, returning to normal levels after 96 hours. The fishes exposed to all salt concentrations had plasma glucose increased after transportation, except the treatment with 8 g of salt/L of water, returning to normal levels within 24 hours. In the second experiment, the fishes transported at different densities with 8 g of salt/L of water did not present a significant change in plasma cortisol after transportation, but plasma glucose increased after transportation at all fish densities, returning to normal levels in 24 hours. Fish transported at a density of 200 kg/m3 of water had 11% mortality in one of the replicates. For tambaqui transportation with 8 g of salt/L of water, maximum density should be 150 kg/m3 of water. At this density water parameter levels are adequate, stress responses are minimum and there is no fish mortality. |

No primeiro experimento foram testadas diferentes concentrações de sal de cozinha (NaCl) na água; no segundo, o transporte foi realizado por três horas em caixas de plástico de 200 L estocadas com diferentes densidades de peixe, com 8 g de sal/L de água. O cortisol plasmático dos peixes sofreu aumento significativo após o transporte no tratamento sem sal e com 2 g de sal/L de água, retornando para níveis normais após 96 horas. A glicose plasmática dos peixes sofreu aumento após o transporte em todas as concentrações de sal testadas, com exceção da com 8 g/L de água, retornando para níveis normais em 24 horas. Nos peixes transportados no segundo experimento, com 8 g de sal/L de água, não foi verificada mudança significativa no cortisol plasmático, mas a glicose aumentou significativamente em todas as densidades após o transporte, retornando para níveis normais em 24 horas. Houve mortalidade de 11% em uma das repetições da densidade de 200 kg/m3 de água. Para o transporte com 8 g de sal/L de água, a densidade máxima deve ser de 150 kg/m3 de água. Nesta densidade os parâmetros físico-químicos de qualidade de água se mantêm com características adequadas, as respostas ao estresse são mínimas e não há mortalidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGomes, Levy de CarvalhoLima, Carlos Alberto Rego Monteiro AraujoRoubach, RodrigoUrbinati, Elisabeth Criscuolo2003-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6572Pesquisa Agropecuaria Brasileira; v.38, n.2, fev. 2003; 283-290Pesquisa Agropecuária Brasileira; v.38, n.2, fev. 2003; 283-2901678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6572/3629info:eu-repo/semantics/openAccess2014-08-13T16:29:55Zoai:ojs.seer.sct.embrapa.br:article/6572Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-13T16:29:55Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
