“…However, our data disagrees since high rejection of filamentous and colonial cyanobacteria was found. The absence of differences on pseudofeces releasing observed by Dionisio-Pires et al (2005) could be related to the method used to evaluate the pseudofeces production. They evaluated pseudofeces after the filtration time, although mussels actually keep releasing pseudofeces while they are filtering, which could have led to an underestimation of excreted products.…”

“…There are few experiments focusing on ingestion of filamentous algae by bivalves (Dionisio-Pires et al, 2005;Bontes et al, 2007). Bontes et al (2007) have studied feeding of bivalve Anodonta anatina on filamentous (Planktothrix) and colonial (Microcystis) cyanobacteria.…”

“…Colonies eventually formed in laboratory conditions are usually small and without mucilage with the predominance of single cells (Dionisio-Pires and van Donk, 2002). Laboratory studies under controlled conditions of mussel feeding in the presence of colonial and filamentous cyanobacteria are scarce (Dionisio-Pires et al, 2005;Bontes et al, 2007). Studies performed with natural seston containing natural colonies of Microcystis have found that D. polymorpha promoted the increase of cyanobacteria densities by low filtration on colonies and their rejection as pseudofeces (Baker et al, 1998;Makarewicz et al, 1999;Vanderploeg et al, 2001;Nicholls et al, 2002;Naddafi et al, 2007).…”

Feeding behavior of the invasive bivalve Limnoperna fortunei in the presence of single-celled, colonial, and filamentous cyanobacteria was tested in laboratory experiments to evaluate the effects of size and shape on mussel feeding. The first hypothesis holds that golden mussel filters more efficiently smaller particles, such as single cells of Microcystis, which could be more easily assimilated by its filtering apparatus. The second hypothesis sustains that L. fortunei filters more efficiently rounded colonies, such as Microcystis, which would be more easily ingested than lengthy filamentous, such as Planktothrix. Filtration rates of golden mussel in the presence of single-celled, colonial and filamentous cyanobacteria were similar. Nevertheless, there was a great difference in the ingestion and pseudofeces production rates. Single cells were widely accepted as food, while filamentous and colonial cyanobacteria were massively expelled as pseudofeces. The results confirmed the first hypothesis that golden mussel prefers to ingest smaller particles. The second hypothesis was rejected since filamentous were preferentially ingested than colonial cyanobacteria. Golden mussel has the potential to remove toxic cells (Microcystis), however this potential would be reduced in cyanobacteria blooms, where colonial forms which are preferentially rejected by L. fortunei, are predominant. In this case, the presence of this invasive bivalve could also enhance the occurrence of blooms by rejecting colonial and filamentous cyanobacteria in pseudofeces.Keywords: golden mussel, Microcystis, Planktothrix, filtration rates, exotic species.

Water managers worldwide are facing the serious problem of dense blooms of cyanobacteria in surface waters. In the quest for the optimal method to combat cyanobacterial dominance, many questions and many possible solutions arise. This paper presents a three-phase strategy to fight harmful cyanobacterial proliferation. Water managers who apply this strategy can generate a tailor-made set of measures. The three phases consist of (1) defining the ecological water quality targets of the waterbody in question, (2) assessing its current ecological state, and (3) selecting which measures will yield optimal results. The paper provides assistance in the quantitative diagnosis of the state of both shallow and deep temperate freshwater lakes by means of a lake system analysis, and presents a survey of measures. Measures are divided into two sets. Preventive measures are based on switching to a clear state (shallow lake) or reducing the overall cyanobacterial biomass (deep lake). They are subdivided into nutrient reduction, hydromorphological adjustments, and food web management. Concerning nutrient reduction, in many situations phosphorus management alone should suffice. Nitrogen management can be important to increase the species diversity of macrophytes, or to relieve downstream (marine) consequences. Control measures (including mitigation) have a direct impact on cyanobacterial blooms by biomass removal, flushing, or mixing; however, the number of proven technologies is limited.

“…Although there were conflicting conclusions drawn from early studies on feeding selectivity by zebra mussels [43][44][45][46][47], more recent studies have shown clearly that zebra mussels can be selective feeders, especially on colonial cyanobacteria like Microcystis [48][49][50]. Large cells and colonial or filamentous forms, such as cyanobacteria and diatoms, are often not drawn into the siphon [48,49,51]. For Microcystis specifically, a recent study demonstrated selectivity for only single cells or colonies smaller than 80 µm diameter [50].…”

Phytoplankton Communities in Green Bay, Lake Michigan after Invasion by Dreissenid Mussels: Increased Dominance by Cyanobacteria

Biological invasions of aquatic systems disrupt ecological communities, and cause major changes in diversity and ecosystem function. The Laurentian Great Lakes of North America have been dramatically altered by such invasions, especially zebra (Dreissena polymorpha) and quagga (D. rostriformis bugensis) mussels. Responses to mussel invasions have included increased water clarity, and decreased chlorophyll and phytoplankton abundance. Although not all systems have responded similarly, in general, mussels have changed nutrient dynamics and physical habitat conditions. Therefore examination of different impacts can help us further understand mechanisms that underlie ecosystem responses to biological invasions. To aid our understanding of ecosystem impacts, we sampled established locations along a well-studied trophic gradient in Green Bay, Lake Michigan, after the 1993 zebra mussel invasion. A strong trophic gradient remained during the period sampled after the mussel invasion (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012). However, mean summer chlorophyll increased and other measures of phytoplankton biomass (microscope and electronic cell counting) did not change significantly. Multivariate analyses of phytoplankton community structure demonstrate a significant community shift after the invasion. Cyanobacteria increased in dominance, with 682Microcystis becoming the major summer taxon in lower Green Bay. Diatom diversity and abundance also increased and Chlorophyta became rare. Phytoplankton responses along the trophic gradient of Green Bay to zebra mussel invasion highlight the importance of mussel effects on nutrient dynamics and phytoplankton diversity and function.
