In this farming approach, seaweeds and other extractive
organisms (e.g. filter-feeding invertebrates) convert dissolved inorganic
and suspended organic nutrients, produced by fed aquaculture (e.g.
finfish and shrimp), into additional crops. However, to encourage
stakeholder investment (finfish and seaweed farmers) it will be necessary
to design profitable and environmentally sustainable systems which
couple nutrient removal efficiency with high productivity
