“…S1 in the Supplement), showing much more sparsely connected food webs in bare sand sites. The AMI, which assesses the developmental status of an ecosystem and quantifies how orderly and coherently food web flows are connected, is indeed highest for reef areas, which is consistent with the stabilising effect of the ecosystem engineering activities of L. conchilega (Godet et al 2009, Rabaut et al 2009). The higher AMI values resulting from the stabilised conditions within the reef are in line with the AMI values measured in the absence of resuspension of the microphyto benthic biofilm in the Bay of Marennes-Oléron (Saint-Béat et al 2014).…”

“…In the early of 2010, the Yantai government gradually removed most of the raft culture to achieve a better landscape for tourism along the coastal zone of Sishili Bay. Several studies had shown the negative impact on the environment from aquaculture, including the effects of waste products on benthic and planktonic communities (Primavera, 2006;Borja et al, 2009c), the spread of pests (Forrest et al, 2009), the effects of increased biodeposition (Canford et al, 2009) and functional value of coastal ecosystem (Godet et al, 2009). Although we could not get the quantitative assessment of the effect of removing raft culture upon the ES of coastal water in the present work, raft culture removal is certainly to be beneficial for water and benthic quality in this area in the long run.…”

To assess the current benthic ecological health and the recovery process of the benthic ecosystem, four surveys were conducted in 2010 and 2011. The AMBI and M-AMBI were applied to assess the benthic ecological status. The ecological status of the Sishili Bay and Taozi Bay was ''moderate'' to ''good'' at most sampling stations during four surveys, but some stations were degraded due to pollution and eutrophication induced by human activities. The ecological status improved after removal of the marine raft culture and minimizing the amount of waste water discharged into the coastal waters of Yantai. The AMBI and M-AMBI could be used as suitable bio-indicator indices to assess the benthic ecological status of coastal waters in Yantai, Shandong Province.

“…Other types, however, might have long-term effects on the environment, such as changes to benthic engineers, and indirectly birds, or via the re-suspension of anoxic sediment and modification of sediment composition (Coen 1995, Kaiser et al 1996, Spencer et al 1997, Pranovi et al 2003, Badino et al 2004, Toupoint et al 2008, Godet et al 2009). The modified tulip harvester used at Chuckanut Shellfish farm was not found to have negative effects on benthos or sediment quality, based on the data collected at the same time as this study.…”

The carrying capacity of a 2.4 ha Manila clam Venerupis philippinarum farm, using mechanised harvesting in North Puget Sound, WA, USA, was determined by means of an ecological model; the results were also scaled to Puget Sound as a whole. An individual Manila clam growth model was developed, calibrated and validated for the commercial farm, together with a macroalgal model to simulate fouling of the predator nets by seaweeds. Both models are based on our previously developed generic frameworks for bivalves (AquaShell) and seaweeds (AquaFrond). For the most part, equations are taken or adapted from the literature and parameterised for the studied site. The individual models were incorporated into the Farm Aquaculture Resource Management (FARM) model to simulate the production cycle, environmental effects and economic optimisation of culture. Both the individual and farm-scale models are built using object-oriented programming. Potential effects of clam production on seaweed growth were analysed and found to be about 10% above background. The FARM model was also used to classify the farm area with respect to its eutrophication status, by applying the Assessment of Estuarine Trophic Status (ASSETS) model. Farm production ranging from 32 to 45 t of clams per year is well reproduced by the model. Harvest yield is very sensitive to mortality, and profitability is very sensitive to seed costs. Manila clam culture provides a potential nutrient credit trading value of over US $41 000 per year, over 1000 Population-Equivalents (PEQ, i.e. loading from humans or equivalent loading from agriculture or industry) with respect to eutrophication control. The potential income would add 21% to the annual profit ($194 900) from clam sales. A scaling exercise to the whole of Puget Sound is in reasonable agreement with declared production (difference of 16%), and suggests that clams provide a significant ecosystem service, of the order of 90 000 PEQ per year.
