“…Strohmeier et al (2012) found that when total cell volume was dominated by small particles, the particle size most efficiently retained decreased (to 6-16 lm). At times when total cell volume was dominated by larger cells, capture efficiency increased to larger particles (20-30 lm).…”

“…For bacteria, the retention relative to the retention of nanophytoplankton varied between 1 and 26 % and for picophytoplankton, retention varied between 11 and 64 %. Mussels can lower the retention efficiency for small particles to some extent by widening the interfilamentary distances of the ctenidium or by shifting the movement of the latero-frontal cilia to the side, so cilia no longer block the passage of smaller particles (Atkins 1937;Dral 1967;Barillé et al 1993;Strohmeier et al 2012).…”

“…Numerous studies, starting with a study by Møhlenberg and Riisgård (1978), have reported on the particle size range that can be retained by adult mussels (see for overview Strohmeier et al 2012). For a long time, it is was assumed that mussels do not efficiently retain smaller particles, with studies reporting on 90 % retention for 3-lm particles by Mytilus edulis, while 1-lm particles are retained with 50 % efficiency only (Møhlenberg and Riisgård 1978).…”

Filtration capacity and feeding behaviour has been intensely studied for adult mussels (Mytilus edulis), but less information is available for juvenile mussels (1.5-25 mm, \1 year), especially in natural sea water. The recent introduction of mussel seed collectors in the Netherlands prompted the need for more detailed information on juvenile mussel behaviour. To estimate the impact of juvenile populations on ecosystem carrying capacity, information on clearance rate as well as usage of different prey items is essential. Clearance rates were measured in an experimental study, incubating juvenile mussels in natural sea water. Rates were related to isometrics as well as specified for the prey items bacteria, picophytoplankton (\3 lm), nanophytoplankton (3-20 lm), and ciliates. Results showed that the clearance rate of juvenile mussels depends on shell length 2 , while the relationship between clearance rate and weight was more variable. Length is thus a better parameter for estimating clearance rate than weight. Ciliates and nanophytoplankton were cleared at comparable, but variable rates, while picoalgae were cleared from the water at the rate of 11-64 % compared to nanophytoplankton. For bacteria, the clearance rate was on average 9 %. This study showed different retention of particles of similar size (picoalgae and bacteria) as well as variability in particle retention for the different prey items. This variable retention efficiency could not be related to seston concentration nor to dominance in cell size. The results from this study can be used to estimate the effect of mussel seed collectors on the carrying capacity of the Dutch Wadden Sea.

“…Since these heterotrophs are the main predators on bacteria and small phytoplankton, the removal of these predators by bivalves might alter the competitive outcome between small and larger algae. Since smaller algal cells (< 3 µm) are less well retained compared to larger cells (> 3 µm; Riisgård & Møhlenberg 1979, but see Strohmeier et al 2012) and since the small cells are assumed to be better competitors for light and nutrients (Riegman et al 1993), an increase in small-sized phytoplankton abundance could be expected to occur under heavy filtration pressure. The few studies that included heterotrophic plankton when examining the effect of bivalves on the plankton community found a decrease in microzooplankton as a result of bivalve grazing (Lam-Hoai et al 1997, Pace et al 1998, Trottet et al 2008b, Froján et al 2014.…”

Pelagic mussel collectors provide an alternative to fishing for mussel seed from natural beds. These collectors, which have been recently introduced in the Dutch part of the Wadden Sea, facilitate the settlement and survival of blue mussel Mytilus edulis larvae. We assessed the removal of plankton by juvenile mussels and the recovery of plankton after filtration. A mesocosm experiment, using natural sea water, was executed on 12 occasions from June to October in 2010 and 2011. Mussel filtration resulted in large reductions in nanophytoplankton, ciliate and total chlorophyll biomasses (65−62%), while picophytoplankton and bacterial biomasses were reduced to a lower extent (38 and 18%). After filtration, mussels were removed and the plankton community was allowed to recover for 8 d, which is the average residence time of water in the area. During this recovery period, net growth rates of bacteria, pico-and nanophytoplankton increased initially in the mussel-filtered mesocosms, but at the end of the recovery period, growth rates were similar in mussel-filtered and control mesocosms. At the end of the recovery period, plankton concentrations between control and mussel mesocosms were not statistically different despite the initial large reduction due to mussel filtration. Our results suggest that nutrients released by mussels during filtration might have stimulated the filtered plankton community, enabling recovery to filtration within 8 d.
