Resumo: Phosphorous is an essential mineral for fishes, because it acts on various metabolic processes. However, high levels may jeopardize the water quality, and its lack could promote deficiency to animals. The aim of this study was to evaluate the productive performance of silver catfish juveniles reared in net cages and fed with diets containing different total phosphorus contents. A total of 600 silver catfish juveniles, with initial weight of 6.88 ± 0.26 g and 9.28 ± 0.99 cm, were randomly distributed in 20 net cages, in a stocking density of 30 fish per cage. A completely randomized design, with four treatments, different total phosphorus contents (0.65%, 0.80%, 0.95%, and 1.10%), and five replicates were used. These contents affected (p < 0,05) the final weight, length, weight gain, specific growth rate, and condition factor. However, the survival rate and feed conversion did not differ (p > 0,05) among treatments. Thus, it is possible to recommend the commercial use of 0.80% total phosphorus in diets for silver catfish juveniles, providing a good productive performance and, above all, reducing the pollution caused by those diets.

Porém, níveis elevados podem comprometer a qualidade da água, e a sua falta pode provocar deficiência aos animais. O presente estudo objetivou avaliar o desempenho produtivo de juvenis de jundiá criados em tanques-rede, alimentados com rações constituídas por diferentes níveis de fósforo total. Foram utilizados 600 juvenis de jundiá, com massa inicial de 6,88 ± 0,26 g e 9,28 ± 0,99 cm, distribuídos, aleatoriamente, em 20 tanques-rede, na densidade de estocagem de 30 peixes por tanque. Utilizou-se delineamento inteiramente casualizado, com quatro tratamentos, diferentes níveis de fósforo total (0,65%; 0,80%; 0,95%; e 1,10%) e cinco repetições. Estes níveis afetaram (p < 0,05) a massa final, comprimento final, ganho de massa, taxa de crescimento específico e fator de condição. Contudo, a sobrevivência e conversão alimentar não se alteraram, em função dos tratamentos. Pode-se recomendar, comercialmente, a utilização de 0,80% de fósforo total, em rações para juvenis de jundiá, proporcionando bom desempenho produtivo e, principalmente, diminuindo o efeito poluidor das rações.Escola de Agronomia - Universidade Federal de Goiás2011-12-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/savehttps://revistas.ufg.br/pat/article/view/15017Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 41, n. 4, Oct./Dec. 2011; 559-563Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 41, n. 4, out./dez. 2011; 559-563Pesquisa Agropecuária Tropical; v. 41, n. 4, out./dez. 2011; 559-5631983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/15017/9995Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessDiemer, OdairBoscolo, Wilson RogérioSignor, Arcangelo AugustoSary, CesarNeu, Dacley HertesFeiden, Aldi2020-07-09T19:36:13Zoai:ojs.revistas.ufg.br:article/15017Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:52.864125Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
