“…As expected, the sharp decrease of Chl a in the benthic boundary layer coincided with an equivalent increase in phaeopigments, a product of chlorophyll digestion (Welschmeyer and Lorenzen 1985). Similar CBLs above dense communities of benthic suspension feeders were found in both temperate communities (Frechette and Bourget 1985;Dolmer 2000;Ackerman et al 2001) and coral reefs (Yahel et al , 2005. The depletion intensity near the bed can be characterized using the steepness of the concentration gradient (Wildish and Kristmanson 1997).…”

Grazing on phytoplankton by a section of the fringing coral reef in Eilat, the Gulf of Aqaba, Red Sea, was studied using the control-volume approach, a direct, nonintrusive technique common in engineering studies. Concentrations of chlorophyll a were measured using four vertical arrays of pumps, 10 pumps on each, that defined an imaginary box (i.e., the control volume), extending from the bed to surface, overlying a section of the sloping fore-reef .100 m 2 in size. Concurrent velocity measurements were made at the center of the box using a vertical array of acoustic current meters. Together, the concentration and velocity measurements allowed us to compute phytoplankton fluxes in and out of the control volume. While phytoplankton patchiness and other turbulent variations in concentration introduced significant variability, mass balances of fluxes into and out of the box indicate a flow-dependent grazing rate of approximately 10 m d 21 to 20 m d 21 . This value was larger than, but not statistically different from, values derived from an ''a priori estimate'' (calculated based on the density and feeding rates of benthic grazers) and an estimate computed from the observed near-bed gradient of Chl a. Phytoplankton grazing is a principal pathway through which allochthonous nutrients are imported to the reef community from the flowing water.

“…Mass-transfer limitation of benthic secondary production has been demonstrated in other systems, such as estuaries, with dense populations of suspension feeders (Jones et al 2009), but the supporting evidence in lakes has been relatively sparse and no direct demonstrations of growth inhibition on the lake bottom have previously been presented. Among the Great Lakes, Ackerman et al (2001) was the first to demonstrate seston depletion above zebra mussel beds in western Lake Erie based on water-column profile sampling in the autumn. Chl a and TSS depletion was demonstrated over mussel beds, but not over sandy sites in the coastal zone of this area of Lake Ontario (G. Martin, pers.…”

“…Among studies conducted in the Laurentian Great Lakes, zones of seston depletion have been reported above beds of the invasive and prolific dreissenid mussels (i.e., zebra [Dreissena polymorpha] and quagga [D. bugensis] mussels) in the shallow west basin of Lake Erie (Ackerman et al 2001;Edwards et al 2005). However, the importance of invasive dreissenid mussels in controlling primary production has been debated, based on disagreement about how much water is refiltered by the benthic mussels (MacIsaac et al 1992;Yu and Culver 1999;Edwards et al 2005).…”

A deep chlorophyll maximum nourishes benthic filter feeders in the coastal zone of a large clear lake

Water column profiles demonstrated that a deep chlorophyll maximum (DCM) in the littoral zone of Lake Ontario intersected the benthos during the development of stratification. We hypothesized that elevated food supply near the lake bottom may be nourishing littoral-zone benthic suspension feeders during this time. Chlorophyll fluorescence was monitored at three heights above the lake bottom, together with near-bottom water velocity using down-facing acoustic Doppler current profilers (ADCPs), at three coastal stations along a crossshore transect. Concurrently, growth rates of quagga mussels (Dreissena bugensis) caged at the lake bottom were compared with mussels suspended 2 m above the bottom. Over a 3-month period beginning April, caged lakebottom mussels grew rapidly (mean biomass-specific growth rate 5 1.08 yr 21 ), while over a 3-month period beginning July, bottom mussels experienced a decrease in biomass (20.74 yr 21 ). Suspended mussels always grew significantly faster than bottom mussels (2.3 and 2.2 yr 21 in Apr and Jul experiments, respectively), affirming previously predicted growth inhibition on the lake bottom due to seston depletion. The different growth rate between seasons of the caged-bottom mussels was most likely attributable to differences in near-bottom chlorophyll concentrations. There was significantly higher chlorophyll a concentration near the lake bottom during the April experiment (average of two stations closest to shore 5 2.7 mg L 21 ) relative to the July experiment (0.21 mg L 21 at the same stations). We suggest that littoral-zone quagga mussels are nourished during the onset of stratification via development of a DCM.

“…Introducing filter-feeding bivalves at an appropriate density can effectively reduce the phytoplankton biomass (Richard and Sergej 2003;Hwang et al 2004;Stadmark and Conley 2011). Many researchers are attempting to use this measure to restore eutrophic waterbodies worldwide, especially to control the overgrowth of phytoplankton (Ackerman et al 2001;Hakenkamp et al 2001;Souchu et al 2001;Fulford et al 2007). …”

A field simulation experiment was conducted to test the hypothesis that altering bivalve aquaculture methods could promote the restoration of eutrophic waterbodies. We used three aquaculture methods -benthic aquaculture, suspended aquaculture, and macrophytes/bivalve combined aquaculture -to (1) investigate their effects on seston removal through monitoring water turbidity, pelagic and benthic algae, and (2) compare their impacts on the phosphorus (P) balance at the water-sediment interface by determining different forms of P contents in the water and sediments. The results showed that the seston removal effects did not differ significantly among these three aquaculture methods. Furthermore, the changes of all investigated P parameters in the water and sediments showed that P release occurred in the benthic and suspended aquaculture treatments. The suspended aquaculture strengthened the regeneration of P from sediments into the water compared with the benthic aquaculture. In addition, the results of a principal component and classification analysis showed that macrophytes/bivalve combined aquaculture promoted the maintenance of restoration effects and P balance at the water-sediment interface. In conclusion, benthic aquaculture coupled with replanting submerged macrophytes is a better choice for water managers when using biomanipulation of bivalves to remedy eutrophic waterbodies.
