Resumo: The objective of this study was to evaluate the effect of feed deprivation on juvenile tambaqui (Colossoma macropomum) growth parameters and body composition. In a complete randomized design, one hundred and eighty fishes, weighting 75.68±8.62 g were maintained in twelve 180-L tanks and submitted to four feed deprivation periods (0, 14, 21 and 28 days). Average fish weight at the end of feed deprivation period tended to be lower as deprivation period increased. At the end of the experiment only the fishes submitted to 14 days of feed deprivation attained similar weight to fish fed without restriction. Condition factor did not show any differences among treatments at the final of the deprivation period or at the end of the experiment. Specific growth rates and hepatosomatic index were similar among all treatments. Fish submitted to deprivation showed the highest daily feed consumption and lower feed efficiency values. Moisture and body protein contents were higher when feed deprivation increased but there was not a significant variation among ether extract levels. Tambaqui juveniles display compensatory growth when submitted to feed deprivation.

Em um delineamento inteiramente casualizado, 180 juvenis pesando 75,68±8,62 g foram distribuídos em 12 tanques de 180 L e submetidos a quatro períodos de privação (0, 14, 21 e 28 dias). A massa média dos peixes ao final do período de privação alimentar foi menor à medida que o tempo de privação aumentou. Ao final do experimento, somente peixes submetidos a 14 dias de privação alcançaram a massa dos peixes alimentados sem restrição. O fator de condição não revelou diferenças significativas entre tratamentos ao final do período de privação ou ao final do experimento. As taxas de crescimento específico e o índice hepatossomático foram similares entre todos os tratamentos. Os peixes submetidos à privação exibiram os maiores valores de consumo diário de ração e os menores valores de eficiência alimentar. As porcentagens de umidade e proteína corporal foram maiores quanto maior o tempo de privação, mas não houve variações significativas dos níveis de extrato etéreo. Juvenis de tambaqui apresentam crescimento compensatório quando submetidos à privação alimentar.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraItuassú, Daniel RabelloSantos, Gin Robson Santos dosRoubach, RodrigoPereira-Filho, Manoel2004-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6896Pesquisa Agropecuaria Brasileira; v.39, n.12, dez. 2004; 1199-1203Pesquisa Agropecuária Brasileira; v.39, n.12, dez. 2004; 1199-12031678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6896/3952info:eu-repo/semantics/openAccess2014-09-08T17:33:05Zoai:ojs.seer.sct.embrapa.br:article/6896Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-08T17:33:05Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
