Abstract

Water quality determines the success or failure of fish researches. A series of rectangular concrete tanks covered with nylon nets were evaluated as a pattern for conduction essay with aquatic animals, when environment conditions must be the same. Physical and chemical characteristics of water were observed. The tanks were populated with ten juvenile pacu (Piaractus mesopotamicus) which were fed ad libitum twice a day. The experiment was carried out between November and February 1992/1993. In the middle of experiment five fishes were slaughtered in order to keep the biomass adequate until the end (87 days). Unsuitable limnologic conditions were detected in the lower waterflow tanks. The increased biomass and decreased waterflow were related to increased mortality and diseases. This kind of serial tanks building allows homogeneous environmental conditions and the waterflow was the parameter which must be carefully monitored.

KEY-WORDS: Tanks; water quality; fish.
