| dc.description | The aim of this study was to evaluate the effect of replacing animal protein with vegetable protein sources on the productive performance of Astyanax altiparanae (lambari-do-rabo-amarelo). Five experimental diets were fo rmulated with increasing replacement levels of animal protein by vegetable protein. A total of 9000 individuals (i nitial mean weight 1.18 ± 0.12 g, initial mean length 2.1 ± 0.3 cm) were distributed in 20 net cages (1 m 3 ) with a density of 450 ind. m -3 . Cages were randomly placed in a pond (180 m 2 , 1.5 m deep, 10% water renewal per day). Afte r 63 days of cultivation, total count and individual biometrics from 20% of each experimental unit were taken. Mean weight, total length, survival, feed conversion, biomass weight gain and proximate body composition were evaluated. The experimental design was completely randomized with five treatments and four replications. The reduction in the formulation cost achieved by increasing levels of vegetable protein compensated the slight decrease in biomass gain. Besides that, inclusio n of vegetable protein resulted in greater fat deposition, suggesting future exploration of A. altiparanae as a functional food. | |
