Fluorometer Controlled Apparatus Designed for Long-Duration Algal-Feeding Experiments and Environmental Effect Studies with Mussels

Test of fluorometer controlled apparatus (FCA). Measurement of filtration rate with a varying number of mussels placed in the experimental aquarium. (a) Total volume of algal suspension added () when an algal stock suspension ( cells mL−1) is used for keeping the algal concentration in the aquarium constant (4,380 ± 590 cells mL−1). Initially, 15 mussels (mean ± S.D., shell length = mm) were used; later after 1.5 h the number of mussels was reduced to 9, and further after 3 h to 3 mussels. (b) Calculated filtration rate (, ◯) based on recorded dosing-pump rate of algal stock () at the end of each period according to (2).
