Abstract
Filtration and ingestion rates of Branchionus plicatilis, fed with four separate algae, have been studied in a wide range (up to 200 µg · ml−1) of food concentrations, commonly used in mass culture. With Nannochloris oculata, Nannochloris maculata and Nannochloropsis oculata filtration rates with increasing cell concentration at low and moderate food levels, and remain constant at higher concentrations. Ingestion rates increase with cell density at very low concentrations, 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 15 × 106 cells · ml−1.
