Abstract
An aquaculture system for allowing live seafood such as clam seeds to grow on a floatation raft which can be positioned in water dock spaces of a marina. A first embodiment allows for an air source such as a regenerative blower to pump air into airlifts under the floatation raft causing seawater to become aerated to flow into and up through screens in container units in the raft allowing for the live seafood on the screens to become both aerated and fed. A second embodiment is a downwell unit where the aerated water flows down the container units through the screens. The upwell air lifts can be modified with spray arm attachments to convert the system from upwell to downwell flow operations. The airlifts can have forty-five degree angled cut bottoms, and include extension tubes for allowing deeper seawater to be introduced into the system. Removable filters can be attached to the airlifts to filter out undesirable contaminants from the system.
