A submersible platform intended to perform the functions of feeding distribution, production control and command of the operations inherent to fish farming in submersible cages, which has the ability to submerge under adverse environmental conditions, returning to the surface, once the environmental conditions so do allow it, enabling thereby the fish farming in offshore spaces. For this purpose it includes a vertical central structure, which constitutes the central core of the platform around which it is arranged the upper structure, which has an outer circulating and mooring space for service vessels, the access to its interior being made through doors, and a lower structure, inside which there are ration storage silos, as well as an insufflation ballasting and deballasting central chamber, which allows the submersion and the emersion of the platform, the balance of the platform being ensured by an additional ballasting and deballasting arrangement within each silo, to compensate for the weight of the consumed ration.
