Modelling biogeochemical fluxes across a Mediterranean fish cage farm

An integrated approach is described for modelling interactions between off-shore fish cages and biogeochemical fluxes of carbon (C), nitrogen (N) and phosphorus (P). Two individual-based population dynamic models for European seabass Dicentrarchus labrax and gilthead seabream Sparus aurata were coupled with a Lagrangian deposition and a benthic degradation model. The individual models explicitl...

Simulating Crop Growth and Biogeochemical Fluxes in Response to Land Management Using the SALUS Model

The Green Revolution, through the adoption of new crop varieties, irrigation, and agrochemicals, saved about 1 billion people from famine by increasing global food production (FAO 2011). We now recognize that these enormous gains in agricultural production were accompanied by harm to agriculture’s natural resource base, jeopardizing our future ability to meet human food, fuel, and fiber needs f...

Influence of intertidal Manila clam Venerupis philippinarum aquaculture on biogeochemical fluxes

Bivalve aquaculture introduces high densities of farmed organisms to the natural environment with potential consequences on a number of ecosystem processes, including modification of nutrient fluxes (e.g. NH4, NOX, PO4, and Si(OH)4) and benthic respiration, and may impact benthic communities. Infaunal clam culture may influence the environment due to the clams themselves [their metabolic proces...
