Abstract:
The objective of the present work was to determine the effect of the enrichment of rotifers (Brachionus plicatilis) and brine shrimp (Artemia sp.) with different commercial emulsions and microalgae on polyunsaturated fatty acid (PUFA) composition of gilthead sea bream larvae, Sparus aurata. Rotifers were fed four enrichment diets (marine Chlorella sp., and three commercial emulsions: Algal RotiferoTM, FrippakTM booster and SelcoTM). The enrichment of Artemia sp. (Artemia SystemsTM, AF type) was carried out with instar I nauplii at a density of 250-300 nauplii/ml in 20 1 conical tanks, using two commercial emulsions (TrofficTM and SelcoTM) and a microalga (Chlorella sp.). The results showed that enriched preys were deficient in PUFA n-3 and may not provide the nutritional requirements of sea bream larvae, although the enrichment methodology seems to be efficient in order to incorporate in the larvae the fatty acid treatment.
