Resumo: The objective of this work was to evaluate the effect of different color tanks on Brycon orthotaenia larviculture, during the fi rst ten days of rearing. Light color tanks (white, light blue and light green) and darktanks (brown and black) were evaluated. The fi shes were fed with Prochilodus costatus larvae until the 5th day and, from the 3rd day on, commercial dry feed with 55% crude protein was also supplied. The growth, survival and Fulton’s condition factor were evaluated. At fi ve days of feed, the weight, total length and specifi c growthrate (SGR) were similar among treatments. However, after ten days, the animals kept in dark tanks showed the lowest weight and total length; but the SGR was similar despite the different color tanks. The Fulton’scondition factor, observed at the end of the experiment, was lower in animals reared in dark tanks. The survival was lower in black tanks, at fi ve and ten days of rearing. The best survival, at the end of the experiment, was observed in brown, light green and white tanks. Light tanks are recommended for B. orthotaenia larviculture, for animals’ best development and survival.

O objetivo deste trabalho foi avaliar o efeito de diferentes cores de tanques na larvicultura de Brycon  orthotaenia, durante os primeiros dez dias de criação. Foram avaliados tanques de cores claras (branco, azulclaro e verde claro) e escuras (marrom e preto). Como alimento, utilizaram-se larvas de Prochilodus costatus, até o quinto dia de alimentação, e a partir do terceiro dia foi também fornecida ração comercial com 55% de proteína bruta. Foram analisados: o crescimento, a sobrevivência e o fator de condição de Fulton. Aos cinco dias,tanto o peso como o comprimento total e a taxa de crescimento específi co (TCE) foram semelhantes entre os tratamentos. No entanto, aos dez dias, animais mantidos em tanques de cores escuras apresentaram menor peso e comprimento total, porém, com TCE semelhante apesar das diferentes cores de tanque. O fator de condição de Fulton, ao fi nal do experimento, foi menor nos animais mantidos em tanques escuros. A sobrevivência foi menor em tanques de cor preta, aos cinco e dez dias de criação. Os maiores valores foram registrados nos tanques de cores marrom, verde claro e branco. Tanques claros são recomendados para a larvicultura de B. orthotaenia, pelo melhor desempenho e sobrevivência dos animais.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFapemig e CNPqPedreira, Marcelo MattosLuz, Ronald KennedySantos, José Cláudio Epaminondas dosMattioli, Cristiano CamposSilva, Camila Lacerda2008-10-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/818Pesquisa Agropecuaria Brasileira; v.43, n.10, out. 2008; 1365-1369Pesquisa Agropecuária Brasileira; v.43, n.10, out. 2008; 1365-13691678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/818/5525https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/818/543info:eu-repo/semantics/openAccess2014-07-17T17:36:12Zoai:ojs.seer.sct.embrapa.br:article/818Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-17T17:36:12Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
