Abstract

The invention provides a plant for the storage of fish and shellfish that includes a net cage for submerging in a body of water.

The roof conforms to a frustoconical shape when in use and includes a central buoyant member in an upper end thereof. In use, the roof extends slackly from the central buoyant member to the points of attachment at the surrounding walls. The surrounding walls are vertically supported by a plurality of buoyant bodies attached to the upper edge of the walls. The entire cage is supported in water by a support section supplied with a buoyant element. The support section is, in turn, held in place by an anchoring section that includes a plurality of substantially parallel vertical cables that are anchored to bottom. Because the anchoring cables are vertical, the plant is able to move laterally, and downwardly, under forces of strong wind, wave, or current action and thereby become completely submerged to protect the plant, and enclosed fish, fr…
