Resumo: | The present research aimed to assess different feeding rates in Colossoma macropomum (tambaqui) farming in excavated pounds, for a period of twenty months (August 2015 to April 2017). For this study 300 fish were selected, with initial average weight of 50 g each individual, in which four feeding rates were tested: 0.5 (T1), 1.0 (T2), 1.5 (T3) and 2.0% (T4) of the living fish weight per day (FW day-1). The fish feed used in the experiment was extruded commercial containing 22% of crude protein. Periodical (biweekly) samplings were carried out for measuring weight (g) and length (cm) of individuals, simultaneously monitoring of water quality parameters. Throughout the research, the limnological variables remained within the limits set for the cultivation of tropical fish. The results suggest that it is possible to manage the tambaqui (feed rate in relation to the FW of fish per day) in stages of cultivation: phase 1 (≈ 50 to ≈ 250 g) forage fish with 0.5% rate; phase 2 (≈ 250 to ≈ 1000 g) with a rate of 2.0%, and phase 3 (≈ 1000 the ≈ 2000 g) feed fish with 1.5% rate of FW day-1. Besides, it is necessary that the support capacity used in the fish farm stay between 800 to 1000 g/m², since larger values resulted in a low zoo-technical yield of individuals. Fish treated with 1.5% of the FW day-1 presented the bests finals total apparent food conversion values (tAFC) = 2.2 and weight (2.11 kg), suggesting that this feeding rate is the most efficient and economically appropriate for the tambaqui cultivation.Keywords: Colossoma macropomum; zootechnical performance; fish farming. |

CULTIVATION OF TAMBAQUIS FROM PRE-FATTENING TO SLAUGHTER WITH DIFFERENT FEEDING RATESCULTIVO DE TAMBAQUIS DA PRÉ-ENGORDA AO ABATE COM DIFERENTES TAXAS DE ARRAÇOAMENTOThe present research aimed to assess different feeding rates in Colossoma macropomum (tambaqui) farming in excavated pounds, for a period of twenty months (August 2015 to April 2017).

Foram selecionados para o estudo 300 peixes, com peso médio inicial de 50 g cada indivíduo, nos quais foram testadas quatro taxas de arraçoamento: 0,5 (T1), 1,0 (T2), 1,5 (T3) e 2,0% (T4) do peso vivo dos animais ao dia (PV dia-1). A ração utilizada no experimento foi a comercial extrusada contendo 22% de proteína bruta. Foram realizadas biometrias quinzenais para a determinação do peso (g) e comprimento (cm) dos indivíduos, simultaneamente ao monitoramento de parâmetros da qualidade de água. As variáveis limnológicas permaneceram dentro dos limites estabelecidos para o cultivo de peixes tropicais durante todo o período experimental. Os resultados sugerem que é possível gerenciar a alimentação do tambaqui (taxa de ração em relação ao PV do peixe ao dia) por etapas de cultivo: fase 1 (≈ 50 a ≈ 250 g) arraçoar com a taxa de 0,5%; fase 2 (≈ 250 a ≈ 1000g) com taxa de 2,0% e fase 3 (≈ 1000 a ≈ 2000 g) taxa de 1,5% do PV dia-1. Ainda, é necessário que a capacidade de suporte utilizada na piscicultura esteja entre 800 a 1000 g/m², uma vez que valores maiores acarretaram em um baixo rendimento zootécnico dos indivíduos. Os peixes tratados com 1,5% do PV dia-1 apresentaram os melhores valores finais de conversão alimentar aparente total (CAAt) = 2,2 e peso (2,11 kg), sugerindo que esta taxa de arraçoamento foi a mais eficiente para o cultivo de tambaqui, assim como a mais adequada economicamente.Palavras-chave: Colossoma macropomum, desempenho zootécnico, piscicultura.Universidade Federal do AmapáMarcos de Almeida Mereles, Universidade Federal de Rondônia - UNIR, Conselho Nacional de Desenvolvimento Científico e Tecnológico - CNPq.Oliveira, Cidiane MeloSousa, Raniere Garcez Costa2017-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Avaliado pelos Paresapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/358910.18561/2179-5746/biotaamazonia.v7n4p20-25Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 7, n. 4 (2017); 20-252179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPporhttps://periodicos.unifap.br/index.php/biota/article/view/3589/v7n4p20-25.pdfAmazoniaDireitos autorais 2018 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2018-03-20T19:55:42Zoai:ojs.pkp.sfu.ca:article/3589Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2018-03-20T19:55:42Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false |
