Paddle-wheel aerator is surface aeration system which can be vertical shaft or horizontal shaft that producing a large air-water interface the transfer of oxygen from atmosphere is enhanced.
The importance of Pond aerator includes the following advantages:
Reduces the concentrations of ammonia, nitrites and carbon dioxide.
Increases pH level of pond water.
Increases the carrying capacity of an aquaculture system.
Increases fish growth.
Regulates water temperature especially as this can affect dissolved oxygen (DO).
Used to control thermal stratification.
Reduces fish mortality.
Enhances fish reproduction systems.
Reduces level of salinity especially during time of low rainfall.
