Notes

Filtration and ingestion rates of Brachionus plicatilis, fed with four separate algae, have been studied in a wide range (up to 200 ug/ml) of food concentrations, commonly used in mass culture, with Nannochloris oculata, Nannochloris maculata and Nannochloropsis oculata filtration rates decrease with increasing cell concentration at low and moderate food levels, and remain constant at moderate densities, and increase again at higher food levels. The results are different with rotifers fed on Nannochloropsis gaditana since both filtration and ingestion rates decrease at cell concentrations above 15x10E6 cells/ml.
