Biofouling & parasites?
Let nano-cavitation help you!

Aqua Farming Solutions B.V. is a subsidiary of H2O Technics B.V., specialist in solutions for fish farms. Sea lice are a big problem for salmon farmers. This crustacean, which is usually smaller than 1 cm, attaches itself to the skin of the salmon. There, it finds its way through the mucus layer and the skin into the salmon’s bloodstream, where it feeds. The small creatures grow and the females lay their eggs.

Currently, sea lice are controlled with pesticides. The use of these harmful substances has substantially increased over the past years. However, sea lice have become resistant to these pesticides. Currently, there is a sea lice infestation that could be explained by this resistance. Another disadvantage: these pesticides are not selective and are, therefore, also lethal to crabs, lobsters, shrimp and more. Residues have been found in underground waters.

AFS developed an environmentally friendly solution.


The C-Dome contains powerful AFS C-110 resonators and is operated by a unique computer system, which is installed in two waterproof casings. The C-Dome is positioned in the centre of the cage and the waterproof casings are mounted onto the cage frame.

The C-Dome has a built-in air chamber, allowing it to float at the desired level. It is made of 100% polyethylene. The C-Dome has a 70 cm diameter and weighs approx. 20 kg.

Since fish cages come in all shapes and sizes, we have developed the V-Dome.

The V-Dome holds AFS C-110 resonators which can be fixed at any desired angle, making the system suitable for all cage models. The waterproof casing with the unique computer system and the V-Dome are both mounted onto the cage frame.
