“…Enrichment of OM, OC and TN in sediments produced by biodeposits of suspension feeders has been found in various coastal wa ters (Vinther & Holmer 2008, Yuan et al 2010, Rampazzo et al 2013. This study also found that the OM concentration in sediments from traps containing bay scal lops was significantly higher than those in reference traps, which suggested that the bay scallops may have a preference for the organic-enriched matter in the water column.…”

Anthropogenic inputs of nutrients and trace elements have globally significant impacts on coastal waters. In order to evaluate the effect of the filter-feeding bay scallop Argopecten irradians on benthic−pelagic coupling in a eutrophic estuary (Laizhou Bay), biodeposition of total suspended materials, particulate nutrient (C, N, P) and trace elements (Cu, Zn, Pb, Cr, Cd, Hg, As) were determined using modified sediment traps during autumn 2013. Results showed that biodeposition rates of the bay scallops were rather high compared with those reported for other bivalves. The allometric relationship between the biodeposition rate (BDR; g ind. −1 d −1) and soft tissue dry weight (W; g ind. −1) was modeled (BDR = aW b) with the value of a being 1.24 in September and dropping to 0.96 in October. The biodeposition contributed to the enrichment of organic matter, C and N in the local sediment. Trace element concentrations in the scallop biodeposits were significantly higher than those of the natural surrounding sediments, especially during the months of October and November. A. irradians significantly increases the mass fluxes from the water column to the bottom, with estimated 1140 tonnes of total suspended material being deposited to the seabed each day in the culture zone. Results also suggest that biotransformation and biodeposition by such efficient filter-feeders may play a pivotal role in the fate and transportation of particulate nutrient and trace elements in aquatic ecosystems. In coastal waters and estuaries subject to anthropogenic inputs, suspended bivalve aquaculture could be environmentally advantageous via intense filtering and biodeposition, potentially mitigating eutrophication and trace element pressures.

“…In a within‐habitat context, mussels can facilitate eelgrass growth by filtering plankton and increasing light availability (Wall, Peterson, & Gobler, 2008), and by fertilizing the sediment through pseudofeces deposition (Reusch, Chapman, & Gröger, 1994). Here again though, context‐dependency matters, as in high‐nutrient areas, fertilization may instead limit eelgrass growth by increasing epiphyte growth (Vinther & Holmer, 2008; Wagner et al, 2012). Similarly, in areas with organic matter‐rich sediments, mussels can instead negatively affect eelgrass by increasing sulphide stress (Vinther & Holmer, 2008).…”

Vegetated marine and freshwater habitats are being increasingly lost around the world. Habitat restoration is a critical step for conserving these valuable habitats, but new approaches are needed to increase restoration success and ensure their survival. We investigated interactions between plants and bivalves through a review and analysis of 491 studies, determined the effects, mechanisms and key environmental variables involved in and driving positive and negative interactions, and produced guidelines for integrating positive interactions into restoration efforts in different habitats. Fifty per cent of all interactions (both correlative and experimental studies) were positive. These were predominant between epifaunal bivalves and plants in all habitats, and between infaunal bivalves and plants in subtidal habitats. Plants primarily promoted bivalve survival and abundance by providing substrate and shelter, while bivalves promoted plant growth and survival by stabilizing and fertilizing the sediment, and reducing water turbidity. The prevalence of positive interactions increased with water temperature in subtidal habitats, but decreased with water temperature in intertidal habitats. The subset of studies conducted in a restoration context also showed mostly positive interactions. Twenty‐five per cent of all interactions were negative, and these were predominant between plants and infaunal bivalves in intertidal habitats, except sulphide‐metabolizing bivalves, which facilitated plant survival. Interactions involving non‐native species were also mostly negative. Synthesis and applications. Promoting facilitative interactions through plant–bivalve co‐restoration can increase restoration success. The prevalence of positive interactions depends on habitat and environmental conditions such as temperature, and was especially important in subtidal habitats (involving both infaunal and epifaunal bivalves) and in intertidal habitats (involving only epifaunal bivalves). Thus sites and species for co‐restoration must be carefully chosen to maximize the chances of success. If done properly, co‐restoration could increase initial survival, persistence and resilience of foundation species, and promote the recovery of associated biodiversity and ecosystem services.

“…The accompanying stimulation of benthic carbon mineralization reduces O 2 availability, transforms the relative importance of processes involved in nitrogen turnover, and reduces overall N removal via denitrification (e.g., Christensen et al 2003;Nizzoli et al 2006). Furthermore, increased deposition can change the faunal community structure and reduce the potential for benthic primary production in the vicinity of the farms (Christensen et al 2003;Richard et al 2007;Vinther and Holmer 2008). In Limfjorden, impacts of natural bottom mussel culture on the benthic species diversity and sediment characteristics such as grain size and content of organic material have been reported and discussed (Ysebaert et al 2009).…”

Long-line mussel farming is well established in many coastal areas around the world, and the concurrent carbon enrichment below farms potentially can have local environmental impacts. The degradation of released mussel (Mytilus edulis) pellets was investigated by a number of complementary incubation approaches. After 140 h in suspension, most of the labile fraction of the pellet material had been degraded. However, because of the shallow water depth at our study site (8 m), only a minute fraction of carbon was released to the water column during sinking, of which~50% was rapidly turned over. Pellets settling at the sediment in realistic concentrations immediately stimulated the benthic O2 uptake. The elevated O2 uptake gradually declined and reached the background level after 96 h, at which time~25% of the added material had been degraded. The main fraction of pellets (75%) was more refractory and remained in the sediment where it was either retained or degraded on much longer time scales. The quantitative response of benthic pellet enrichment observed in the laboratory was confirmed by in situ trap measurements and incubations of sediment collected below and away from active farms.Résumé : L'élevage des moules sur filières est bien établi dans plusieurs régions côtières dans le monde et l'enrichissement en carbone sous les élevages peut potentiellement générer des impacts environnementaux locaux. Nous avons étu-dié la dégradation des boulettes fécales libérées par les moules (Mytilus edulis) par plusieurs méthodologies complémentaires d'incubation. Après 140 h en suspension, la plus grande partie de la portion labile du matériel des boulettes est dégradée. Cependant, à cause de la faible profondeur de l'eau à notre site d'étude (8 m), seulement une fraction minuscule du carbone est libérée dans la colonne d'eau durant la sédimentation, dont~50 % est rapidement recyclé. Les boulettes qui se sont déposées sur le sédiment en concentrations réalistes ont immédiatement stimulé la consommation benthique de O2. La consommation accrue de O2 a graduellement décliné et atteint le niveau de base après 96 h; à ce moment,~25 % du matériel ajouté était dégradé. La fraction principale (75 %) des boulettes est plus réfractaire et demeure dans le sédiment où elle est retenue ou se dégrade sur des échelles temporelles beaucoup plus longues. La réponse quantitative à l'enrichissement benthique en boulettes observée en laboratoire a pu être confirmée en nature par des mesures dans des collecteurs in situ et par l'incubation de sédiments prélevés sous les élevages actifs et loin de ces élevages.[Traduit par la Rédaction]
