“…The ability of submerged macrophytes to moderate the structure of food webs with respect to lake eutrophication management has been intensively studied in recent years (Marklund and Sandsten, 2002;Muylaert et al, 2003;Genkai-Kato, 2007). Many lake managers have adopted the option of increasing macrophyte abundance to restore eutrophic waters, with a view to improve water quality, increase water transparency and reduce phytoplankton biomass (Qiu et al, 2001;Wang et al, 2009).…”

“…During the 1970s, nuisance algal blooms frequently occurred and macrophytes declined considerably. Some dramatic changes took place in the lake during the 1980s, and the most striking one among them may be the sudden disappearance of water bloom in 1986, which have not recurred (Qiu et al, 2001). This lake has been segmented into several parts by causeways across the lake proper and the bay region (still allowing the passage of water between adjacent parts through a watercourse).…”

“…Their contribution to improved water quality is affected through a series of biotic interactions and physico-chemical reactions with water and sediments (Ciurli et al, 2009). They limit the growth of planktonic algae through competition for nutrients (Carpenter and Lodge, 1986;Blindow et al, 1993;Nakai et al, 1996), alter the physico-chemical conditions of sediment (Qiu et al, 2001), reduce the resuspension of sediment materials, oxidize the water column, and actively absorb nutrients (Barko and James, 1998).…”

-Eutrophication resulting from nutrient loading to freshwater habitats is a severe problem, leading to degradation of ecosystems, including deterioration of water quality, water clarity and loss of biodiversity. Measures enacted to restore degraded freshwater ecosystems often involve the reintroduction of submerged plants and aquatic animals with beneficial ecological functions. In a mesocosm experiment, three treatments (planting with Vallisneria natans, introduction of the snail Bellamya aeruginosa and a combined treatment with both plants and snails) were compared with controls to evaluate their effects on trophic state. The total nitrogen (TN), total phosphorus (TP) and chlorophyll a (Chl a) concentrations of planktonic and benthic algal samples were determined every two weeks, along with light intensity at the sediment surface. The plant-only treatment significantly reduced the TN levels and planktonic and benthic algal biomass and increased the light intensity at the sediment surface. The snail-only treatment reduced the concentrations of TN and reduced planktonic and benthic algal biomass. The combined treatment decreased the concentrations of TN and TP, reduced planktonic algal biomass and increased the light intensity on the sediment surface. The results indicate that while submerged plants and snails can both improve water quality, the most pronounced effect in aquatic ecosystems is achieved by their presence in combination. A combined reintroduction approach may provide enhanced benefits in restoring the eutrophic ecosystems, following the reduction of external nutrient loading.Keywords: submerged plant / snail / coexistence / planktonic algae / benthic algae Résumé -Effets des escargots, des plantes submergées et de leur coexistence sur l'eutrophisation dans les écosystèmes aquatiques. L'eutrophisation résultant de la charge nutritive dans les habitats d'eau douce est un problème grave, entraînant une dégradation des écosystèmes, y compris la détérioration de la qualité de l'eau, de la clarté de l'eau et la perte de biodiversité. Les mesures adoptées pour restaurer les écosystèmes d'eau douce dégradés impliquent souvent la réintroduction de plantes submergées et d'animaux aquatiques ayant des fonctions écologiques bénéfiques. Dans une expérience en mésocosme, trois traitements (plantation avec Vallisneria natans, introduction de l'escargot Bellamya aeruginosa et traitement combiné avec les plantes et les escargots) ont été comparés aux témoins pour évaluer leurs effets sur l'état trophique. Les concentrations d'azote total (TN), de phosphore total (TP) et de chlorophylle a (Chl a), des échantillons d'algues planctoniques et benthiques ont été déterminées toutes les deux semaines, ainsi que l'intensité de la lumière à la surface des sédiments. Le traitement aux plantes seules a réduit significativement les niveaux de TN et la biomasse d'algues planctoniques et benthiques et a augmenté l'intensité lumineuse à la surface des sédiments. Le traitement avec l'escargot seul a réduit les concentrati...
