Resumo: The objective of this study was to evaluate the aflatoxins effects on the growth of jundiá fingerlings (Rhamdia quelen), and its deposition on the tissue of fishes fed with diets containing different concentrations of the micotoxin. A total of 960 fingerlings were used in two experiments, the first with 45 days, and the second with 35 days. The experimental facilities were composed by a thermoregulated water reused system. In the first experiment, concentrations of 41, 90 and 204 ppb of aflatoxins kg-1 were tested. In the second experiment, 350, 757 and 1,177 ppb aflatoxins kg-1 were also evaluated. The following parameters were estimated: weight, total and standard length, dressing carcass, condition factor, weight gain, survival and aflatoxin deposition in the liver and carcass. In the first experiment, it was observed a decrease of weight and length in fish fed with 204 ppb aflatoxins kg-1. In the second experiment, significant difference in the tested variables did not occurred. For feed over 350 ppb kg-1, alterations in the liver and tissues occurred without compromising the growth for 35 days.

Foram utilizados 960 alevinos, em dois experimentos, o primeiro com duração de 45 dias e o segundo com 35 dias. As instalações experimentais foram compostas por um sistema termorregulado de recirculação de água. No primeiro experimento, foram avaliados os teores de 41, 90 e 204 ppb de aflatoxinas kg-1 de alimento e no segundo experimento, 350, 757 e 1.177 ppb de aflatoxinas kg-1 de alimento. Foram estimados os seguintes parâmetros: peso médio, comprimento total e padrão, rendimento de carcaça, fator de condição, ganho diário, sobrevivência e deposição de aflatoxinas no fígado e na carcaça. Observou-se, no primeiro experimento, diminuição do peso e comprimento dos peixes alimentados com 204 ppb aflatoxinas kg-1. No segundo experimento, não ocorreu diferença significativa nas variáveis analisadas. A partir de 350 ppb kg-1, ocorreram alterações no fígado e tecidos, sem comprometer o crescimento, durante os 35 diasPesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLopes, Paulo Rodinei SoaresNeto, João RadünzMallmann, Carlos AugustoLazzari, RafaelPedron, Fábio de AraújoVeiverberg, Cátia Aline2005-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7060Pesquisa Agropecuaria Brasileira; v.40, n.10, out. 2005; 1029-1034Pesquisa Agropecuária Brasileira; v.40, n.10, out. 2005; 1029-10341678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7060/4108info:eu-repo/semantics/openAccess2014-09-19T19:22:03Zoai:ojs.seer.sct.embrapa.br:article/7060Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-19T19:22:03Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
