ABSTRACT:
An aqua culture facility and method using a pneumatic pump for displacement of water or other liquid located in a confined space having rigid bottom and side walls which form an interior surface of the space, with a flexible liner having the same contour as the space in which the liquid is confined. The confined space is a culture chamber and open at the top side, such as a fish pond. The flexible liner is comprised of two or more flexible membranes which are in sealing engagement at their edge portions to form a sealed compartment. There is an air inlet-outlet means through which gas or liquid can be introduced to inflate and then to exhaust the air from the sealed compartment. The flexible liner has a flexible membrane in contact with the rigid bottom and side walls of the confined space and is larger then the interior surface of the confined space. The placed flexible membrane liner is covered with water and seeded with organisms to create the culture chamber. To harvest the organisms, air is introduced through the air inlet-outlet means, thus forming a pillow which pumps and displaces the culture water to a drainage end for collection, treatment or relocation of the organisms.
