Resumo: | The aim of this study was to evaluate the effect of high stocking densities on survival, growth and feed conversion rates of Litopenaeus vannamei shrimp, in final growout phase, in a Biofloc Technology (BFT) culture system, keeping the same water parameters for all treatments. Shrimps (11.96 ± 1.14 g) were stocked in microcosms (0.50/m2 tanks), connected to a BFT system raceway. The study was carried out for 45 days. The shrimp were stocked at densities of 150, 300, 450 and 600 shrimp/m2. Bioflocs were collected for analysis of proximate composition. The results were submitted to one-way ANOVA, and differences were compared by Tukey test (? = 0.05). In T300 and T450, growth and survival were not affected by high stocking densities. The highest biomass reached (T450) was 5.1kg/m² and the best feed conversion rate was 1.54 in T150. The results of this study indicate that stocking densities in the proposed system can be high, but not exceeding 450 shrimp/m². Furthermore, even maintaining the same water parameters for all treatments, there was a negative effect between density and shrimp growth, confirming that this effect is behavioral.KEYWORDS: Biofloc Technology; growth parameters; shrimp growth out. |

Os camarões (11,96 ± 1,14g) foram estocados em microcosmos (tanques de 0,50 m2), conectados a um raceway de cultivo BFT. O experimento teve duração de 45 dias. Os camarões foram estocados nas densidades de 150, 300, 450 e 600 camarões/m2. Bioflocos foram coletados para análise de composição proximal. Os resultados foram submetidos à ANOVA uma via e as diferenças foram comparadas pelo teste de Tukey (? = 0.05). No T300 e T450, o crescimento e sobrevivência dos camarões não foram afetados pelas altas densidades. A maior biomassa alcançada (T450) foi de 5,1 kg/m2 e a melhor conversão alimentar foi de 1,54 no T150. Os resultados deste estudo indicam que as densidades de estocagem no sistema proposto podem ser elevadas, mas não superiores a 450 camarões/m2. Observou-se ainda que mesmo se a qualidade de água for mantida igual para todos os tratamentos, há efeito negativo entre densidade e crescimento dos camarões, confirmando que esse efeito é comportamental.PALAVRAS-CHAVE: engorda de camarões; parâmetros zootécnicos; tecnologia bioflocos.Universidade Federal de Goiás2013-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/1041910.5216/cab.v14i3.10419Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 14 No. 3 (2013); 279-287Ciência Animal Brasileira / Brazilian Animal Science; v. 14 n. 3 (2013); 279-2871809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/10419/15194https://revistas.ufg.br/vet/article/view/10419/15195Silva, Adriana FerreiraLara, Gabriele RodriguesBallester, Eduardo CupertinoKrumennauer, DarianoAbreu, Paulo CesarWasielesky, Wilsoninfo:eu-repo/semantics/openAccess2013-10-14T12:20:03Zoai:ojs.revistas.ufg.br:article/10419Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:44.804067Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
