<p>Floating rings (1) with a base (2) and intermediary slide rod (3) and wire (4), and a fish pen (5) fastened to the floating ring (1) and resting on the base (2). A polygonal base ring (6) with angles (7) and a centre tank (9) and stays (10, 12) stretched in between. The centre tank (9) can be filled with a required mixture of fluid and of gas in order to obtain the necessary buoyancy to lift the base (2). To the floating rings (1) are fastened slide rods (3) weighted by mooring blocks (13) at the opposite extremity, and wires (4) attached to the base ring (6). A second set of loops (15) is fastened to the fish pen (5) and slide along the slide rods (3). Floats (16) are positioned between the loops (15).</p> |
