“…This is somewhat higher than efficiencies reported in other studies. Trottet et al (2008), using natural sea water, found clearance rates of adult mussels on bacteria to be close to zero. Nielsen and Maar (2007) found no removal of bacteria above a mussel bed.…”

“…The highest retention efficiency for these picoparticles corresponded to relative small (8 lm) particles dominating total carbon availability, while at the site with a lower retention the carbon availability was dominated by 12-to 16-lm particles. Trottet et al (2008) investigated the clearance rates on different phytoplankton species, heterotrophic flagellates, and ciliates. Relative clearance rates between species and taxa varied throughout the year.…”

“…These experiments resulted in estimates of the maximum clearance rate, while it can be expected that under natural conditions, clearance rates will be lower. The need for information on actual realised clearance rates under natural conditions and the specific usage of natural plankton by these dense collections of juvenile mussels has been recognised (Bunt et al 1992;Cranford et al 2003Cranford et al , 2011Trottet et al 2008).…”

“…Although phytoplankton was traditionally considered the main food source (Nielsen and Maar 2007), several studies have stated the importance of other food particles like dead organic material (Dame and Dankers 1988) and bacteria attached to this (Newell et al 1989), microzooplankton (Horsted et al 1988;Kreeger and Newell 1996;Trottet et al 2008) and, for larger mussels ([22 mm;Horsted et al 1988), mesozooplankton (Davenport et al 2000;Wong and Levinton 2006;Lehane and Davenport 2006).…”

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.
