Abstract:
Vertical pump, pump sprayer, propeller-aspirator-pump. paddle wheel, and diffused-
air aerators powered by electric motors or by takeoffs from farm tractors are used widely to
aerate aquaculture ponds. Performance tests suggesled that electric paddle wheel aerators are the
most efficient in transfening oxygen and circulating pond water. A design for a highly efficient
paddle wheel aerator is described. Aeration can improve dissolved oxygen concentrations,
enhance the efficiency of feed utilization, and increase aquacultural production and profits. Aerator
placement and the use of aerator controllers are discussed.
