Effects of Different Commercial Feeds and Enrichments on Biochemical Composition and Fatty Acid Profile of Rotifer (Brachionus Plicatilis, Müller 1786) and Artemia Franciscana

Özet

The objective of the present study was to determine the effects of several commercial rotifer feeds and enrichments ongrowth, biochemical and fatty acid composition of L-type rotifer and Artemia franciscana nauplii. In experiment I, fiveexperimental diets (M0 Plus, S.Parkle, w-3 Yeast 60, Beaker’s yeast and Chlorella vulgaris) were tested for rotifer cultureperformance and in the second experiment six enrichers (w-3 Olio, n-3 Top Rich, Red Pepper, Culture Selco, microalgaemixture (Dunaliella salina + Chlorella vulgaris) and Emulsion T) were evaluated for the fatty acid composition of rotifer andArtemia franciscana. In experiment I, rotifers fed S.Parkle and Beaker’s yeast showed better biomass production and eggdensity while the number of egg carrying female number was higher. In experiment II, rotifers enriched n-3 Top Rich showedbetter n-3 HUFA retention whereas Artemia franciscana nauplii enriched Red Pepper showed highest HUFA accumulation.Culture Selco seems optimal for artemia enrichment for EPA (20:5n-3) and DHA (22:6n-3) accumulation. In conclusion,Beaker’s yeast is still applicable in comparison to other commercial feeds in rotifer culture. Further study is needed fordetermination of mineral composition of rotifer feeds and commercial enrichments and their retention in live prey and larvaeuse in Turkey.
