Resumo: | In a quantitative field research, the objective of this work was to determine the best stocking density for tambatinga juveniles (Colossoma macropomum × Piaractus brachypomus) in a recirculation system during 50 days of cultivation. Tambatinga juveniles (0.72±0.02 g) were distributed in 0.08 m3 polyethylene boxes with densities of 5, 10 and 15 fish/box, with five replicates per treatment. During the experimental period, water quality, weight gain, apparent feed conversion, specific growth rate, carcass yield, proximate composition and final survival were evaluated. The water parameters remained stable and in the desired range for the species during the experimental period (temperature 25±1.52° C, pH 5.85±0.7 and dissolved oxygen 6.51±0.05 mg L-1). Statistical analyzes showed no significant difference for apparent feed conversion and survival rate. The lowest stocking density (5 fish/box) showed greater weight gain and specific growth rate, while the density of 10 fish/box showed high lipid deposition in the carcass. Aiming at greater weight gain and better specific growth rate, the results indicated that the density of 5 fish/box (0.08 m3), is the most suitable for juveniles of this species. |

Tambatinga juveniles (0,72±0,02 g) se distribuyeron en cajas de polietileno de 0,08 m3 con densidades de 5, 10 y 15 peces/caja, con cinco repeticiones por tratamiento. Durante el período experimental, se evaluaron la calidad del agua, el aumento de peso, la conversión aparente del alimento, la tasa de crecimiento específica, el rendimiento de la canal, la composición próxima y la supervivencia final. Los parámetros del agua permanecieron estables y en el rango deseado para la especie durante el período experimental (temperatura 25±1.52 ° C, pH 5.85±0.7 y oxígeno disuelto 6.51±0.05 mg L-1). Los análisis estadísticos no mostraron diferencias significativas para la conversión aparente de alimento y la tasa de supervivencia. La menor densidad de población (5 peces/caja) mostró un mayor aumento de peso y una tasa de crecimiento específica, mientras que en la densidad de 10 peces/caja mostró una alta deposición de lípidos en la carcasa. Con el objetivo de un mayor aumento de peso y una mejor tasa de crecimiento específico, los resultados indicaron que la densidad de 5 peces/caja (0.08 m3) es la más adecuada para los juveniles de esta especie.Numa pesquisa de campo e de natureza quantitativa, o objetivo deste trabalho foi determinar a melhor densidade de estocagem para juvenis de tambatinga (Colossoma macropomum × Piaractus brachypomus) em um sistema de recirculação durante 50 dias de cultivo. Os juvenis de tambatinga (0,72±0,02 g) foram distribuídos em caixas de polietileno de 0,08 m3 com densidades de 5, 10 e 15 peixes/caixa, com cinco repetições por tratamento. Durante o período experimental foi avaliado a qualidade da água, ganho de peso, conversão alimentar aparente, taxa de crescimento específico, rendimento de carcaça, composição centesimal e sobrevivência final. Os parâmetros da água permaneceram estáveis e na faixa desejada para a espécie durante o período experimental (temperatura 25±1,52° C, pH 5,85±0,7 e oxigênio dissolvido 6,51±0,05 mg L-1). As análises estatísticas não mostraram diferença significativa para conversão alimentar aparente e taxa de sobrevivência. A menor densidade de lotação (5 peixes/caixa) apresentou maior ganho de peso e taxa de crescimento específica, enquanto que na densidade de 10 peixes/caixa apresentou alta deposição lipídica na carcaça. Visando maior ganho de peso e melhor taxa de crescimento específico, os resultados indicaram que a densidade de 5 peixes/caixa (0,08 m3), é a mais adequada para juvenis desta espécie.Research, Society and Development2020-04-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/331710.33448/rsd-v9i5.3317Research, Society and Development; Vol. 9 No. 5; e178953317Research, Society and Development; Vol. 9 Núm. 5; e178953317Research, Society and Development; v. 9 n. 5; e1789533172525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/3317/4730Copyright (c) 2020 Rebeca Maria Sousa, Romério Rodrigues dos Santos Silva, Anália Sousa dos Santos, Camila Vieira da Silva, João Avelar Magalhães, Fabíola Helena dos Santos Fogaça, Jane Mello Lopesinfo:eu-repo/semantics/openAccessSousa, Rebeca MariaSilva, Romério Rodrigues dos SantosSantos, Anália Sousa dosSilva, Camila Vieira daMagalhães, João AvelarFogaça, Fabíola Helena dos SantosLopes, Jane Mello2020-08-20T18:06:36Zoai:ojs.pkp.sfu.ca:article/3317Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:33.397808Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
