Marine aquaculture in an offshore environment requires the use of proven technologies, based on reliable know-how. Chlamys, with its long experience of installations in numerous sites, is the ideal technological partner for the realization of your plant in a cage even at great distances from the coast, whether it is systems in floating or submersible cages.

The assessment of the environmental effects connected to the operation of the production units at sea is a strong point of Chlamys technological know-how, capable of integrating farm design with the environmental assessment of the possible effects on marine communities, in a coordinated process that allows construction of systems perfectly integrated into the carrying capacity of the farming area. This favors a faster and safer acquisition process of the areas under concession, and an easier management of any disputes with other stakeholders, often paying attention to the possible environmental effects of fish farms.
