“…Measured sedimentation rates are in the same range as those reported in earlier studies of mussel farms with similar production size, in both Sweden (Dahlbäck & Gunnarsson 1981) and Denmark (Carlsson et al 2009). However, sedimentation rates at the M2 farm were almost twice as high as at the M3 farm which indicated a higher mussel biomass at M2 compared to M3.…”

“…Based on sediment flux measurements and denitrification rates, N input versus N removal in the underlying sediment was estimated in order to provide insight into N cycling in mussel farm sediment. A similar study investigating the environmental impact of mussel farms has already been performed in Limfjorden, where eutrophication has a significant influence on sediment mineralization rates (Carlsson et al 2009). However, their study provided no detailed insight into N cycling.…”

“…The biodeposits of suspension-feeding bivalves can be rich in carbon (C) and N (Kautsky & Evans 1987), and sedimentation rates 3 to 5 times higher under mussel farms compared to outside reference sites have been reported (Hartstein & Stevens 2005, Carlsson et al 2009). Organic enrichment of underlying sediment may lead to increased mineralization of organic matter, altering sediment biogeochemistry and potentially affecting benthic community structure (Carlsson et al 2009). …”

The biogeochemical impact of 3 long-line mussel farms (M1, M2 and M3) in Lysekil, Sweden, was investigated from before farm establishment until 1.5 yr after operation had begun. Sedimentation, benthic N flux, total oxygen uptake (TOU) and sulfate reduction rate (SRR) were all significantly increased below the mussel lines at all 3 farms. Effects of increased sedimentation rates were revealed by sediment profile imaging and were highest at Stn M2. These effects increased significantly with time of farm operation, indicating the accumulation of organic matter within sediments over time. Furthermore, more total particulate organic N deposited at farm stations was recycled into the water column compared to at reference stations (~45 versus ~13%), indicating an increased release of dissolved inorganic N from sediment below the mussel farms. At one station (M2) with the highest increase in sedimentation rate, denitrification seemed inhibited, while at another station (M3), with a less pronounced increase in sedimentation rate, denitrification was in fact stimulated, accounting for 13% of total sediment N removal. Calculations based on estimated values of N removal through mussel harvest and direct measurements of N input through changes in sedimentation, N regeneration from sediment to the water column through benthic fluxes and changes in denitrification showed, in all cases, a net removal of N from the system, as only 26 to 40% of the total amount of harvested N had been added to the sediments during the growth period.

“…An additional constraint for optimizing an extractive mussel farm is the possible effects on benthic habitat and communities from the deposition of organic matter in mussel faeces and pseudofaeces. Observations of benthic effects from bivalve farming are generally limited to the immediate vicinity of the farm in shallow, poorly flushed regions (Chamberlain et al 2001, Hartstein & Stevens 2005, Hargrave et al 2008, Carlsson et al 2009, Cranford et al 2009. Benthic impacts at the Skive Fjord mussel farm were shown to be limited compared to the surrounding area due to the high rate of sediment organic enrichment from eutrophication (Holmer et al 2015).…”

“…Effects of increased biodeposition below mussel culture units have been reported (e.g. Carlsson et al 2009), but the arguments presented by Stadmark and Conley (2011) fail to include mass balance considerations and does not take into account that mussel biodeposits are not the main driver for benthic processes in nutrient-enriched waters Rose et al 2012).…”

Effects of excess loading of nutrients to the marine environment can be mitigated by mussel cultures, basically through nutrient removal from the marine environment when shellfish are harvested. Shellfish farming also provide other goods and services to the marine environment primarily through the impact on water transparency caused by shellfish filtration. There is an increasing awareness of the mitigation potential in mussel culture in relation to eutrophication, but so far practical examples of culture on full scale devoted to mitigation are few. Further, impact of mussel farming on nutrient cycling, e.g. in the sediments below the culture units, has raised concerns. In this review, we clarify concepts in relation to nutrient mitigation and discuss goods and services delivered by mussel mitigation cultures and their impact on an ecosystem scale based primarily on results from studies in heavily eutrofied estuaries. A multi-criteria approach for site selection is presented based on experiences from Danish waters, and economic aspects of mitigation cultures are analysed in relation to use of the produced mitigation mussels. Future perspectives for extractive cultures are discussed in relation to source of excess nutrients.
