Resumo: The present investigation was carried out to evaluate of the limnological parameters in two ponds stocking pacu (Piaractus mesopotamicus) during 105 days. In one pond (V1) the fishes were fed daily and in the second pond (V2) no food was given for 60 days and the ration was supplied after this period. The values of abiotic parameters as temperature, dissolved oxygen, pH,conductivity, and nutrients were lower in pond V1 compared to V2, probably due the residence time. Pronounced flutuations of limnological parameters between surface,middle and bottom of the ponds were not observed. KEY WORDS: Ponds, management, limnology, fish culture, pacu .

KEY WORDS: Ponds, management, limnology, fish culture, pacu .Em dois viveiros povoados com juvenis de pacu(Piaractus mesopotamicus) foram estudadas algumas variáveisfísicas, químicas e biológicas da água, durante operíodo de 105 dias, com coletas quinzenais pela manhã(9:00 horas). Estes viveiros foram submetidos a diferentestratamentos de acordo com o manejo alimentar: um delescom fornecimento diário de ração; o outro, semarraçoamento durante 60 dias, sendo, após este período,iniciado o fornecimento de ração aos peixes por 30 dias. Aavaliação limnológica da água mostrou que as variáveisestudadas apresentaram pequenas flutuações durante o estudo O curto tempo de residência da água nos viveiros proporcionouuma oxigenação adequada, impedindo oacúmulo de nutrientes a níveis tóxicos, como amônia enitrito. Apesar do arraçoamento diário no viveiro 1 (V 1),os valores de nutrientes, condutividade, alcalinidade, entreoutros, foram mais baixos do que no viveiro 2 (V 2). O curtotempo de residência da água do V1 (1,61 dias), comparadoao V2 (2,22 dias), pode ter afetado essas variáveis. Nãoforam observadas flutuações acentuadas entre superfície,meio e fundo para os parâmetros analisados.PALAVRAS-CHAVE: Viveiros, manejo, variáveis limnológicas, piscicultura, pacu.Universidade Federal de Goiás2006-10-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdfhttps://revistas.ufg.br/vet/article/view/2681110.5216/cab.v1i2.26811Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 1 No. 2 (2000); 115-121Ciência Animal Brasileira / Brazilian Animal Science; v. 1 n. 2 (2000); 115-1211809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/26811/15343Souza, Valéria LeãoSipaúba - Tavares, Lúcia HelenaUrbinati, Elizabeth Criscuoloinfo:eu-repo/semantics/openAccess2019-02-15T14:15:35Zoai:ojs.revistas.ufg.br:article/26811Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:02.677328Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
