Abstract As the worldwide exploitation rate of capture fisheries continues, the
development of sustainable aquaculture practices is increasing to meet the seafood
needs of the growing world population. The demand for aquatic products was
historically satisfied firstly by an effort to expand wild catch and secondly by
increasing land-based and near-shore aquaculture. However, stagnation in wild
catch as well as environmental and societal challenges of land-based and near-shore
aquaculture have greatly promoted efforts to development farming offshore technologies for harsh, high energetic environments. This contribution thus highlights
recent technological approaches based on three sample sites which reach out from
sheltered near-shore aquaculture sites to sites with harsh wave/current conditions. It
compares and evaluates existing technological approaches based on a broad literature review; on this basis, we then strongly advocate for presently available
aquaculture technologies to merge with future offshore structures and platforms and
to unveil its added value through synergetic multi-use concepts. The first example
