Abstract
Clearance and ingestion rates of Brachionus plicatilis were measured using 14C-labeled Isochrysis galbana Tahiti. Experiments were conducted at 20–22 °C, 20 ppt salinity, and algal concentrations ranging from 0.13–64 mg Cl−1. Clearance rates were constant and maximal at concentrations <2 mg Cl−1 with maximum rates ranging from 3.4–6.9 µl ind. hr−l. The ingestion rate varied with food concentration, and was described by a rectilinear model. The maximum ingestion rate varied considerably, and was dependent on the growth rate of the rotifers. Depending on the pre-conditions, B. plicatilis ingested about 0.5 to 2 times its body carbon per day at saturating food concentrations.
