Sustainable growth of non-fed aquaculture can generate valuable ecosystem benefits
Barrett, L.T. et al., Ecosystem Services Fisheries & Aquaculture
Here, we quantify and monetise the impacts of bivalve and seaweed farming on a regulating service (removal of nitrogen from nearshore waters) and a supporting service (habitat provision for species with fisheries value). We estimate that on average, 275–581 kg N ha−1 yr−1 (in harvest units: 4–25 kg N t -1) is removed via bioextraction at oyster, mussel and seaweed farms, with much smaller contributions from enhanced sediment denitrification beneath farms compared to reference sites.
