Mytilus edulis. Mean individual filtration rates (𝐹) measured in two groups of mussels (𝑛=45) exposed during 10 d to 3,310 ± 730 (◯, 𝐿=31.9±1.3 mm) and 8,160±1,140 cells mL⁻¹ (●, 𝐿=32.2±0.6 mm), respectively. The curve for filtration rates measured at the high algal concentration resulting in saturation reduction was obtained from the following equation: 𝐹=𝐹_red+(𝐹₀−𝐹_red)×exp(−𝑡/𝜏), where 𝐹₀=1.9±0.2 L h⁻¹, 𝐹_red=0.24 L h⁻¹, and 𝜏=0.561 d.
