The objective of this study was to analyze the body yield and the chemical composition of catfish (jundia), Rhamdia quelen, reared in net-tanks and fed with diets containing different levels of protein and energy. An initial density of 70 fish/m³, in 18 net-tanks (5.0 m3) was used, for 324 days. A randomized complete design was used, with two factors: Crude Protein (CP) at three levels, 25, 30 and 35%; and Digestible energy (DE) at two levels, 3,250 and 3,500 kcal, […]
