In the present study, the effect of four different oxygen levels on the growth of sea bass was examined. Sea bass, initial mean weight 78,9 ± 3,1 gr were divided into four groups, in which the oxygen levels were set: 3,6 ±0,2 ppm, 4,7 ±0,2 ppm, 6,2 ±0,2 ppm, 8,2 ±0,2 ppm. Τhe experiment lasted nine weeks. The levels were monitored and adjusted using electrodes connected to a computer. In the low oxygen levels there was a decrease in specific growth rate (SGR) and feed efficiency, while there was no significant decrease in appetite and daily feed consumption. The decrease was more evident in the last six week of the experiment. Thus, it is believed that the differences in growth observed were due to differences in feed efficiency.
