Offshore aquaculture is the subject of intense debate, focusing on feasibility, sustainability, and the potential for effective expansion in the context of competing uses of the coastal zone, and a world requirement for an additional 30 million tonnes of aquatic products by 2050.

A modelling framework that integrates the SWAT model for the watershed, 'Delft3D' for ocean circulation and the EcoWin model for long-term (10 year) ecological simulations, was developed for integrated analysis of catchment, inshore waters and offshore aquaculture, providing an approach that addresses production, environmental effects and disease interactions. This framework was tested using a case study in SE Portugal, for a system-scale modelling domain with an ocean area of 470km2 and a coastal watershed area of 627km2.
