Influence of oxygen saturation on feed intake and growth of peled whitefish (Coregonus Peled) in intensive farming

The results of an experimental rearing of peled under different oxygen regimes are presented in this work. Four variants were tested in three repetitions (hypoxia 55-65 %, normoxia 85-95 %, permanent hyperoxia 145-155 % and alternate hyperoxia 145-155 % during the day and 85-95 % overnight). Also the oxygen consumption of fish with weight from 4.5 to 20 g at temperatures of 15, 19 and 23 °C was measured.
