ABSTRACT:
A chamber for breeding and raising marine animals such as fish. The chamber is usable particularly in open water and is composed of a flexible film of plastic material which is inert with respect to a marine environment. The arrangement includes a pump for introducing water under a pressure greater than the surrounding environment into the chamber, and discharge openings through which the water discharges. A farm for raising marine animals can include at least one such chamber connected to a support spar, in the water, and extending vertically. Torus shaped water inflatable rims can be used to maintain the shape of a chamber.
