Pacific white shrimp Litopenaeus vannamei can convert various types of carotenoids into astaxanthin and accumulate them in its body, giving the desired reddish color. In this study, the shrimps were kept in a biofloc aquaculture system away from the coastal zone, fed with commercial feed supplemented with annatto extract (Bixa sp.). The experiment was carried out with a 2 x 4 factorial design with shad levels (50% and 80%) and four feeding regimes (0, 7, 14, and 21 days) to evaluate the most efficient model to promote the increase in the surface color of the shrimp. Leaching in artificial brackish water and the influence of biofloc pigments on shrimp color. According to the results, bixin sprinkled on the feed surface undergoes leaching in brackish water the measure of the time it is immersed. Carotenoids present in the biofloc showed a correlation with chlorophyll content by the R test. Raceway with 80% water shad and feed containing 1,235 mg/Kg of bixin showed the most significant results in the shell color of shrimps (fresh and cooked) and lower ammonia levels.A cor do camarão é importante na escolha do crustáceo pelo consumidor. O camarão branco do Pacífico Litopenaeus vannamei pode converter vários tipos de carotenóides em astaxantina e acumulá-los em seu corpo, dando a cor avermelhada desejada. Neste estudo, os camarões foram mantidos em sistema de aquicultura de bioflocos longe da zona costeira, alimentados com ração comercial suplementada com extrato de urucum (Bixa sp.). O experimento foi conduzido em esquema fatorial 2 x 4 com níveis de sombreamento (50% e 80%) e quatro regimes alimentares (0, 7, 14 e 21 dias) para avaliar o modelo mais eficiente para promover o aumento da superfície cor do camarão. Lixiviação em água salobra artificial e influência dos pigmentos de bioflocos na cor do camarão. De acordo com os resultados, a bixina aspergida na superfície de alimentação sofre lixiviação em água salobra ao longo do tempo em que fica imersa. Os carotenóides presentes no biofloco apresentaram correlação com o teor de clorofila pelo teste R. O canal adutor com 80% de água de sombra e ração contendo 1.235 mg/Kg de bixina apresentou os resultados mais significativos na cor da casca dos camarões (frescos e cozidos) e menores níveis de amônia.engUniversidade Federal de Minas GeraisUFMGBrasilVET - DEPARTAMENTO DE ZOOTECNIAJournal of agricultural studiesCarotenoidesPenaeidaePercolaçãoColor enhancerCarotenoidPenaeidae shrimpPigment leachingShadeInfluence of Annatto (Bixa orellana) extract and different shading levels on Litopenaeus vannamei color reared inland using biofloc technologyInfluência do extrato de urucum (Bixa orellana) e diferentes níveis de sombreamento na cor de Litopenaeus vannamei cultivado em interior utilizando tecnologia de bioflocosinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.macrothink.org/journal/index.php/jas/article/view/20658Daniel Pereira da CostaTainára Cunha GemaqueLeonardo Vaz PereiraAfonso de Liguori OliveiraKleber Campos Miranda Filhoapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
