EXPERIMENTAL METHODOLOGY IN AQUACULTURE - MODIFICATION OF THE FEEDINGRATE OF THE GILTHEAD SEA BREAM SPARUS-AURATA AT A SELF-FEEDER AFTER WEIGHING

The daily feeding rate using a self-feeding method was studied in seve ral groups of gilthead sea bream following weighing. The first day aft er weighing all groups showed a significant decrease in feeding rate u p to 66% in animals of 179 g. A partial compensation for this initial intake deficiency was recorded during the next day. A fluctuating feed ing rate with compensations occurring from one day to the next was als o observed over the study period. The results are discussed on the bas is of methodology and experimental consistency.
