On request we can supply submersible and emerging circular cages. These are similar to the normal floating cages for fish farming use, having as well the same technical specifications, but in addition they have a pneumatic valve system to introduce air and water for immersion and emersion . To immerse the cage all the valves of the cage open and while the water in the tubes, the cage sinks. On the contrary, to raise the cage it is necessary to introduce pressure air in order to let the water out of the pipes.

It can be said that the submersible cages and the nets used in nylon or dyneema are more complete and robust than the common unsinkable ones.
