Through IMTA, some of the food, nutrients and by-products considered “lost” from the fed component are recaptured and converted into harvestable and healthy seafood of commercial value, while biomitigation takes place (partial removal of nutrients and C02, and supplying of oxygen). In this way, some of the externalities of fed monoculture are internalized, hence increasing the overall sustainability, profitability and resilience of aquaculture farms. A major rethinking is needed regarding the definition of an “aquaculture farm" (reinterpreting the notion of site-lease areas) and regarding how it works within an ecosystem, in the context of a broader framework of Integrated Coastal Zone Management (ICZM).
