The control group were fed twice a day from Monday to Friday. Other groups were fed less frequently. The control group had 68 feeding days during the experiment. Treatment 1 had 48 feeding days, treatment 2 43 and treatment 3 38 days. Whole experiment lasted for 13 weeks and during the last four weeks all groups were fed every day from Monday to Friday. Feed intake was continuously monitored. Samples were taken from each tank after four, nine and thirteen weeks. The sampled fish were eviscerated. The liver, visceral fat, emptied stomach and stomach contents were weighed. Stomach volume and liver water content were measured, and blood samples were taken from each sampled fish. The haematocrit and plasma chloride were analysed from the blood samples. At the end of the experiment control group fish were the biggest (235,3 \u00b1 27,8 g) and the treatment 3 fish were the smallest (134,7 \u00b1 24,5 g). There were no significant differences in condition factor, specific growth rate (SGR), feed conversion ratio or stomach volume between the treatments.
