Abstract

A work was done at "Centro de Biologia Aquática - Universidade Católica de Goiás", from August 16 to November 6, 1995, to evaluate the use of brewery by-products as feed for fish growth. Six outdoor tanks (60 m2) were stocked with Colossoma macropomum fingerlings weighing 1.12 ± 0.8 g and at a density of one fish/m2. Feeding pattern was kept in a 6% biomass proportion of each tank daily. A 34% Crude Protein commercial ration was used as control (Treatment II) resulting in a mean final weight of 24.42 g with an average daily gain of 0.34 g against 17.84 g and 0.24 g for treatment I; brewery by-products with 36% Crude Protein, respectively. There was no statistical difference (P>0.05) in apparent feed conversion and mean final weight between treatments, which approves the use of brewery by-products as a partial ingredient in rations for fishes.
