Resumo: The objective of this work was to evaluate the effect of stocking density in Litopenaeus vannamei rearing in fresh water. The evaluated densities were: 5 (D5), 10 (D10), 15 (D15), 20 (D20), 25 (D25) and 30(D30) shrimp per square meter. The experimental design was completely randomized, with two replicates. The performance of shrimp and the physical and chemical parameters of water were evaluated. Mathematical models were generated to estimate the zootechnical parameters of L. vannamei. The mean alkalinity of water was 36.8±3.06 mg L-1, and the mean hardness was 38.21±3.07 mg L-1. At 52 days of rearing, treatment D5 had the best results on weight (5.40±0.99 g) and length (9.50±0.20 cm), but the weight did not differ significantly from treatments D10, D15 and D25. Treatment D25 had the best shrimp survival rate (72.10±9.3%). Based on the mathematical models of weight and length as function of rearing time, it was found that higher stocking densities provide shrimp with less weight and length gain.

Foram avaliadas as seguintes densidades de estocagem: 5 (D5), 10 (D10), 15 (D15), 20 (D20), 25 (D25) e 30 (D30) camarões por metro quadrado. O delineamento experimental foi inteiramente casualizado, com duas repetições. Foram avaliados o desempenho zootécnico dos camarões e os parâmetros físicos e químicos da água. Os parâmetros zootécnicos de L. vannamei foram estimados por meio de modelos matemáticos. A alcalinidade média da água foi de 36,8±3,06 mg L-1, e a dureza média de 38,21±3,07 mg L-1. Aos 52 dias de cultivo, o tratamento D5 foi o que promoveu os melhores resultados em peso (5,40±0,99 g) e comprimento (9,50±0,20 cm), no entanto, não diferiu significativamente dos tratamentos D10, D15 e D25 em termos de peso. O tratamento D25 teve maior sobrevivência de camarões (72,10±9,3%). Com base nos modelos matemáticos de peso e comprimento em função do tempo de cultivo, concluiu-se que maiores densidades de estocagem proporcionam camarões com menores ganhos de peso e comprimento, em comparação com as menores densidades.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPQ)Fonseca, Sthelio Braga daMendes, Paulo de PaulaAlbertim, Cândida Juliana de LyraBittencourt, Cláudio FigueiroaSilva, José Humberto Vilar da2010-12-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/1817Pesquisa Agropecuaria Brasileira; v.44, n.10, out. 2009; 1352-1358Pesquisa Agropecuária Brasileira; v.44, n.10, out. 2009; 1352-13581678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/1817/5851https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1817/1226https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1817/1254info:eu-repo/semantics/openAccess2012-06-17T11:53:42Zoai:ojs.seer.sct.embrapa.br:article/1817Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:53:42Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
