Abstract

The present study evaluated the effects of two stocking densities (20 and 40 fish/m2) and nightly aeration on water quality and growth of pacu, Piaractus mesopotamicus (Holmberg, 1887). Twelve ponds with concrete walls and earthen bottom were used to set 4 treatments with 3 repetitions each. 30-day old fish with average weight (mean standard ± deviation) of 1.93 ± 1.70g in the beginning of the experiment were observed for 60 days. Nightly aeration promoted 5.6 ± 0.5 and 5.8 ± 0.5mg O2/l at dawn in the population densities of 20 and 40 fish/m2, while the unaerated ponds allowed 4.3 ± 0.7 and 3.4 ± 0.7mg O2/l for these densities, respectively. Fish biomass was the only biological parameter increased by nightly aeration, while discrete effects were observed in growth and survival.
