Resumo: The objective of this study was to verify pirarucu Arapaima gigas preferential time of feeding, and the influence of different feeding periods on consumption and weight gain of this species. Three treatments were tested: diurnal feeding (fish fed at 9h and 15h), nocturnal feeding (fish fed at 21h and 3h), and continuous feeding (fish fed at 9h, 15h, 21h and 3h). Each treatment was evaluated in triplicate, and each trial unit had eight fishes with 313 g average weight, stoked into a 1 m3 (1x1x1 m) net cage. The nine net cages were located on a 120 m2 earth pond. The trial lasted for 60 days. Continuous feeding promoted the highest weight and biomass gain, specific growth rate and feed consumption. Nocturnal and diurnal feeding treatments showed similar weight gain; however, diurnal feeding had the best feed conversion ratio. The preferred feeding time for pirarucu was the nocturnal period, mainly at the beginning of night. Data from this study indicated that the preferred feeding time is not the best one for feeding pirarucu on a commercial husbandry. The most indicated feeding period for this species, based on its feed conversion capacity, is diurnal period.

Foram testados três tratamentos: alimentação diurna (peixes alimentados às 9h e 15h), alimentação noturna (peixes alimentados às 21h e 3h) e alimentação contínua (peixes alimentados às 9h, 15h, 21h e 3h). Cada tratamento foi avaliado em triplicata, com cada unidade experimental formada por oito peixes, com peso médio de 313 g, estocados em tanques-redes de 1 m3 (1x1x1 m). Os nove tanques-redes foram alocados em um viveiro escavado de 120 m2. O experimento durou 60 dias. A alimentação contínua promoveu maiores ganhos de peso e biomassa, taxa de crescimento específico e consumo total. Os tratamentos alimentação diurna e alimentação noturna apresentaram ganho de peso semelhante, porém, a alimentação diurna apresentou a melhor conversão alimentar. O período preferencial de alimentação do pirarucu foi o noturno, principalmente no começo da noite. Os dados deste estudo indicam que o horário de preferência alimentar não é o melhor horário de alimentação do pirarucu, em uma criação comercial. O período de alimentação mais indicado para a espécie, baseado na capacidade de conversão alimentar, é o diurno.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCrescêncio, RogerItuassú, Daniel RabelloRoubach, RodrigoFilho, Manoel PereiraCavero, Bruno Adan SagratzkiGandra, André Lima2005-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7087Pesquisa Agropecuaria Brasileira; v.40, n.12, dez. 2005; 1217-1222Pesquisa Agropecuária Brasileira; v.40, n.12, dez. 2005; 1217-12221678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7087/4135info:eu-repo/semantics/openAccess2014-09-19T16:21:13Zoai:ojs.seer.sct.embrapa.br:article/7087Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-19T16:21:13Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
