PONDS IN AQUACULTURE Provide life support (water) Many designs – 1.Non-circulating flow through Re-use (series) 2.Circulating Flow through Re-use Re-circulating 3.Static – minimal water exchange

PONDS IN AQUACULTURE Non-circulating ponds Raceways (concrete or earthen) Standard dimensions: Single or multiple pass (series)

PONDS IN AQUACULTURE Non-circulating ponds Rectangular ponds Used where minimal flows exist Troughs Shallow troughs Deep troughs

PONDS IN AQUACULTURE Non-circulating ponds Silo Water enters bottom exits top Circulating Ponds Rectangular circulating pond Water circulates around center wall

PONDS IN AQUACULTURE Circulating Ponds Fish move against or with current flow Circular Pond Labor intensive

PONDS IN AQUACULTURE Circular Pond Inflow at degrees from horizontal Static ponds No active hydraulic action from entering water Net pens/floating cages Popular in marine environment

PONDS IN AQUACULTURE Lakes Small surface acres Earthen ponds Common in catfish industry
