Further development of proven technology
AKVA group have been working on submersible cages for a long time and the first project was already delivered in 1991. So far, AKVA group have sold 500 different varieties of submersible cages, but the system that is now being developed for salmon is far more automated and advanced.
Moving the salmon through the water column presents many challenges that must be solved. One of the largest challenges is the creation of the artificial airspace the salmon needs to fill the swim bladder and maintain normal behaviour. The salmon is dependent on filling the swim bladder on a regular basis and it must be done without having to raise the cage to the surface. Creating an artificial air pocket that the fish will use is challenging, and technology and biology must co-operate in order to get the desired result.
