Resumo: The objective of this study was to evaluate the growth and economic performance of fat snook (Centropomus parallelus) fed six practical diets, containing different protein levels. Diets were formulated to contain the following protein levels: 375, 395, 416, 438, 473 and 490 g kg-1. Diets were offered until apparent satiation twice a day for 90 days. At the end of the experimental period, the body composition of the fish fed different diets did not differ significantly. The weight gain varied from 2.87±0.09 to 4.74±0.02 g from the lowest to the highest protein concentration. The protein concentration of 490 g kg-1 led to a decrease of 2.86±0.13 R$ kg-1 in the average feeding cost, an increase of 97.82±4.25% in the economic efficiency index, and a reduction of 102.91±4.58% in the cost index. The diet with the highest protein concentration and the energy/protein ratio of 7.27 Mcal kg-1 promotes the best economical and growth performances for juvenile fat snook.

Ao final do experimento, a composição corporal dos peixes alimentados com as diferentes dietas não diferiu significativamente. O ganho em peso variou de 2,87±0,09 a 4,74±0,02 g, da menor para a maior concentração proteica. A concentração proteica de 490 g kg-1 levou à redução de 2,86±0,13 R$ kg-1 no custo médio de alimentação, ao aumento de 97,82±4,25% no índice de eficiência econômica, e à redução de 102,91±4,58% no índice de custo. A dieta com a maior concentração proteica e a relação energia/proteína de 7,27 Mcal kg-1 promove os melhores índices zootécnicos e econômicos para juvenis de robalo-peva. Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraUFSC, Nicoluzzi Indústria de Raçõesde Souza, José HumbertoFracalossi, Débora MachadoGarcia, Alexandre SachsidaRibeiro, Flávio FurtadoTsuzuki, Mônica Yumi2011-05-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/9475Pesquisa Agropecuaria Brasileira; v.46, n.2, fev. 2011; 190-195Pesquisa Agropecuária Brasileira; v.46, n.2, fev. 2011; 190-1951678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/9475/6249https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/9475/4715https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/9475/4716https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/9475/4717https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/9475/5526info:eu-repo/semantics/openAccess2014-05-19T17:21:32Zoai:ojs.seer.sct.embrapa.br:article/9475Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-05-19T17:21:32Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
