Modular low head high volume water pump and aquaculture system

Claim 1

A method for culturing aquatic life in a contained body of water open to the atmosphere, said method comprising the steps of establishing a contained body of water having a central divider with openings at each end of said central divider for passage of water and aquatic life species, placing a low head, low flow-rate high volume modular floating water pump system in one of said openings, said modular floating water pump system comprising an anchored float means supporting water pump means having water intake means in communication with said water body, and outlet means communicating with a series of submerged concentrically disposed conduits in end to end relation, each succeeding conduit having its outlet end interposed in the inlet end of the next larger conduit which inlet is open to said water body so that water flow through one conduit causes reduced pressure at said next larger conduit inlet thereby causing water in said body outside of said next larger conduit to flow into said next larger conduit inlet whereby the amount of water flowing through said conduit is increased in direct proportion to the ratio of the increase in the cross-sectional area of the respective successive conduits and the rate of flow is inversely proportional to said ratio, and circulating said water by means of said system whereby said aquatic life can exist in a moving body of water which brings food and oxygen to said aquatic life and prevents water stagnation.
