Normal weather condition:
A small portion of the cage is out of water. Fish gets atmospherig air.
Self-cleaning of nets by sun and air:
At low stocking density and calm weather, the cage shows half out of water.
The net dries in sun and air. Nets never have to be changed.
Cage is permanently below water trough – fish lives stress-free in their natural environment.
Feeding: The patented automatic feeder press dry pellets into a water stream, which arrives within seconds in the cage-sections at any depth of the cage.
Oxygenation: Diffuse-pipes, fixed on 4 lowest longitude-pipes, bring air or liquid oxygen in each section and atmospherig air into "air-bells".
Harvesting and grading of fish: The section-nets, stored at the axial pipe is pulled from outsite by an endless rope and fixed to a longitude pipe. Slight rotations of the cage push fish to the fish pump.
