The Application of Dynamic Modeling to Prediction of Production Carrying Capacity in Shellfish Farming

Magnitude, spatial scale and optimization of ecosystem services from a nutrient extraction mussel farm in the eutrophic Skive Fjord, Denmark

“…11) were conducted in this study to estimate the optimal farm stocking density for increasing water quality and extracting excess phytoplankton in this highly eutrophic setting. Optimization of commercial shellfish culture is based on the production carrying capacity concept, which is the cultured biomass and/ or growth rate that can be sustained by available food in a given area (Grant & Filgueira 2011). The optimal stocking of a nutrient extraction facility may be expected to be similarly constrained given that the objective is also to harvest the maximum biomass from the farm over a given time, albeit with less concern over product quality.…”

Open water integrated multi-trophic aquaculture: constraints on the effectiveness of mussels as an organic extractive component

“…The maximum production of an organic extractive species crop at any given site is limited by food availability, and this is the basis of the production carrying capacity concept (e.g. Grant & Filgueira 2011). Food depletion by mussels acts as a biological feedback mechanism that limits mussel production (e.g.…”

Global Hindcasts and Future Projections of Coastal Nitrogen and Phosphorus Loads Due to Shellfish and Seaweed Aquaculture

“…Various models are available to analyze water quality and the potential harvest of shellfish at the scale of individual bivalve species (Ross and Nisbet, 1990;Campbell and Newell, 1998;Scholten and Smaal, 1999), shrimp (Lorenzen et al, 1997;Burford and Lorenzen, 2004), bivalves (Grant et al, 1993;Grant, 1996;Grant and Bacher, 1998;Grant and Filgueira, 2011), farms (Ferreira et al, 2007(Ferreira et al, , 2011 or larger systems Bacher et al, 2003;Ferreira et al, 2009;Tett et al, 2011), the interaction between extractive and fed aquaculture , bivalve carrying capacity (Scholten and Smaal, 1999;Grant et al, 2007;Filgueira and Grant, 2009;Filgueira et al, 2010;Guyondet et al, 2010;Grant and Filgueira, 2011), bivalve biodeposition (Cromey et al, 2002;Weise et al, 2009), and nutrient excretion (Sereda and Hudson, 2011 Scheme showing N (left) and P (right) budget terms for: (A) crustaceans, (B) bivalves, (C) gastropods, and (D) seaweed. Intake for crustaceans is from feed, which is an external source.…”
