Özet
Feed consumption ratios of gilthead seabream larvae during first feeding by using microcapsules feeds and rotifer, either together or separately.This study was done to determine the feed consumptions of seabream (Sparus aurata L., 1758) larvae during their first feeding period just after they consumed their egg yolks.During the experiments, the larvae were fed by using rotifers (Brachionus plicatilis Müller, 1786) that were marked with 14 C isotope and by microcapsule feeds which were 50-65 µm in size.Three different feeding regimes were used to feed the larvae.First group were fed by rotifer, second group by microcapsule feeds, and third group by radioactive microcapsule + non-radioactive rotifer.At the end of the study, for 5-days old larvae, the rotifer consumption ratio was found to be 0.347µgl -1 h -1 , microcapsule feed consumption ratio to be 0.152µgl -1 h -1 , and 0.088µgl -1 h -1 for the group in which microcapsule feeds and rotifer were used together.This study showed that sea bream larvae could consume microcapsule feeds during first feeding period, although at lower ratios when compared to live feeds, and that using microcapsule feeds together with rotifer decreased the microcapsule feed consumption ratio.
