A factorial design with four levels of chromium (0, 6, 12, 18 mg kg -1 g g of diet) x two stocking densities (4 and 20 kg m -3 ) x three periods (30, 60 and 90 days) was conducted. No

The effect of stocking density interfered in water quality parameters, with result at fishes performance. And the concentrations of chromium were not sufficient to observe benefits and ensure best performance. Thus, higher concentrations of supplementation may be required by pacu in these conditions of high stocking density. ARTIGO
