The product for the enrichment of aquatic organisms, in particular of filter feeding organisms like rotifers or Artemia, comprises at least 30% on total weight basis a lipid emulsion. The lipid emulsion consists for 25 to 80% by weight of an aqueous phase and for 20 to 75% by weight of a lipid phase dispersed in the aqueous phase. The enrichment product is in the form a water dispersible gelled body having a weight of at least 1 gram. Advantages of the gelled enrichment product is that it can be weighed and dosed more easily and that it can be taken up more efficiently so that higher levels of highly unsaturated fatty acids in Artemia nauplii can be reached and/or so that enrichment of Artemia nauplii is feasible at higher densities, in particular higher than 350 nauplii per ml, whilst still achieving the required enrichment levels. |
