Optimum dietary protein requirement for Amazonian Tambaqui, Colossoma macropomum Cuvier, 1818, fed fish meal free diets

Abstract: Fish meal free diets were formulated to contain graded protein levels as 25% (diet 1), 30% (diet 2), 35% (diet 3) and 40% (diet 4). The diets were fed to tambaqui juveniles (Colossoma macropomum) (46.4 ± 6.3g) in randomly designed recirculating systems for 60 days, to determine the optimum protein requirement for the fish. The final weight of the fish, weight gain (28.1, 28.5, 32.2, 28.0g) and specific growth rate increased (P>0.05) consistently with increasing dietary protein up to treatment with 35% protein … Show more

“…Protein efficiency ratio in this study is quite good compared to research Oishi (2010), which uses 35% protein feed to produce protein efficiency ratio amounted to 1.87 ±0.20. The lower the protein efficiency ratio protein are used to produce the body weight, the better.…”

“…Os valores de composição da carcaça obtidos são semelhantes aos encontrados em outros estudos com tambaqui (LOPES et al, 2010;OISHI et al, 2010;SANTOS et al, 2010;MENDONÇA et al;PEREIRA-JÚNIOR et al, 2013). Embora a granulometria do milho de 500µm tenha melhorado o desempenho zootécnico e a utilização do alimento, essas alterações não foram suficientes para que houvesse mudanças nos parâmetros da carcaça dos peixes.…”
