With the purpose of evaluating the changes and the degree of heterosis on performance and carcass traits of fish from the diallel crossing between Pacu and Tambaqui, four genetic groups were generated through hormonal induction: pacu, tambaqui, tambacu and paqui. For 196 days, 400 juveniles of each genetic group were stocked in a pond divided into four parts of equal size, one for each group. At the end of this period, when the fish weighed on average 1024 g (±115.52 […]

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, […]
