WHY NEED AERATION?

When choosing which type of aerator to use for aquaculture ponds, it is helpful to
know some basic facts about aeration.
Without sufficient oxygen, aquaculture animals will become stressed, sick, and
possibly die. Even when a good quality water source is available, the large inputs of
nutrients and organic matter that result from feeding and animal waste can lead to a
low level of dissolved oxygen in the pond. Good mechanical aerators can effectively
replenish the level of dissolved oxygen in ponds.
Aerators perform two basic functions: they oxygenate water and induce water
circulation. Both functions are important in pond aquaculture. Pond water normally
contains plenty of dissolved oxygen during daylight hours, but in ponds with high
feeding rates and abundant phytoplankton blooms, dissolved oxygen concentrations
may decline to dangerously low levels at night. Aeration can be used during the night
to stabilize dissolved oxygen concentrations within safe ranges.
A moderate degree of water circulation in ponds is beneficial: it prevents stratification
of the water to provide more uniform water quality. Also, organic matter from uneaten
feed, feces, and dead plankton settles to pond bottoms and decomposes. This can
lead to anaerobic conditions in the superficial layers of bottom sediment with the
release of toxic microbial metabolites in the overlying pond water. Induced circulation
of pond water increases water flow and delivery of dissolved oxygen to the surface of
the sediment to lower the possibility of anaerobic conditions at the sediment-water
interface.
"Because of better water and soil quality in response to aeration, fish eat better, have
greater resistance to diseases, suffer less mortality, and achieve better feed
conversion efficiency in aerated ponds than in ponds without aeration.”
