The Danish sea territory spans 105,000 square kilometers of relatively shallow water with salinities ranging from brackish to fully oceanic. The present Danish sea farms are located in the least exposed regions in the Danish fjords and sounds. Environmental constraints are limiting production increase, and new locations in the coastal zone are rarely allocated. The shortage of suitable inshore sites emphasizes the urge to move to more exposed sites where benthic impacts are reduced or eliminated.

The offshore areas of the Danish sea territory holds vast areas with no or negligible activities apart from capture fishery. Venturing into these areas with aquaculture opens a major window of opportunity, but is also a serious challenge being too great for a single company to lift.

The overall purpose of developing the offshore production system is to create the technical foundation for “farming the ocean”. In other words to make it possible to locate cage culture facilities in areas now not considered suitable for fish farming because of their exposure to the physical forces of the open sea.

The project will develop a system based on a combination of the traditionally used circular PE gravity cage system combined with the innovative submersion system. This makes it possible for the present fish farmers to use their existing gear and methodology for harvest, feeding etc. without having to venture into a whole new technological setup.

When the weather changes for the worse, the farmer can submerge the whole system below the wave action and let it stay there till the storm has passed, before he lets the system reappear at the surface and resumes normal operation procedures.

The project is coordinated by Hvalpsund Net, Denmark.
