Growth and blood chemistry of juvenile Neotropical catfish (Lophiosilurus alexandri) self-feeding on diets that differ in protein-to-energy (P:E) ratio

This study evaluated the growth and blood biochemistry were examined in juvenile Lophiosilurus alexandri that were self-feeding on feeds with different protein-to-energy (P:E) ratios. Juveniles (21.10 ± 0.39 g) were stocked at a density of six fish/tank (40 L) photoperiod 12L:12D, equipped with an o...
