What is a paddle wheel aerator?
A paddle wheel is a wheel with a number of paddles set around its edge. Paddle wheels have many uses, from very low-lift water pumping and moving algae culture in raceway ponds to propulsion and flow measurement. In aquaculture, the most important use is aeration.
A paddle wheel aerator floats on the pond surface. An electric motor drives the paddles through a gear reducer; the paddles splash water into the air, where it picks up oxygen, and push a current of oxygenated water across the pond. This both adds dissolved oxygen and keeps the whole pond circulating.
Paddle wheel aerators are a strong choice for medium and large ponds, where moving oxygen-rich water away from the aerator and around the pond matters most.

Benefits of paddle wheel aerators
Raises dissolved oxygen
Splashing and surface agitation transfer oxygen quickly into the water.
Circulates the whole pond
Moves oxygen-rich surface water across the pond and breaks up stratification.
Uniform conditions
Destratification keeps temperature and oxygen levels more even from top to bottom.
Concentrates waste
Water currents gather sludge towards the pond centre, keeping feeding areas cleaner.
Corrosion-resistant build
304 stainless steel frame, shaft and hardware suit salt and saline water.
Handles changing water levels
Floats keep the aerator working as pond levels rise and fall.
How many aerators does a pond need?
Aeration demand depends on stocking density, feed per day, water temperature and pond size. Oxygen demand peaks at night and before dawn, when photosynthesis stops, and rises sharply as biomass and feeding grow through the crop.
A widely used rule of thumb in shrimp farming is about 1 HP of paddle wheel aeration for every 400 to 500 kg of expected harvest biomass. Extensive fish ponds need much less. Place aerators so they create a single circular current around the pond, and add units as biomass increases rather than running the full set from day one.
Monitoring dissolved oxygen with a meter, especially at dawn, is the most reliable way to know whether aeration is adequate.
Choosing an aerator size
General guidance; final sizing depends on stocking and feed.
| Model | Typical use | Notes |
|---|---|---|
| 1 HP, 4 paddles | Small ponds, nursery ponds, supplementary aeration | Easy to handle and move |
| 2 HP, 4 paddles | Medium ponds, semi-intensive culture | Common all-round choice |
| 3 HP, 6 paddles | Large ponds, intensive shrimp culture | More oxygen transfer and circulation per unit |
Care and spares
- Check the gear reducer oil at the intervals in the manual and top up or change as needed.
- Inspect paddles and floats for cracks or damage; replace broken paddles promptly to keep the wheel balanced.
- Keep motor and cable connections dry and protected; use proper starters and protection on the supply.
- Rinse salt deposits off the frame and motor housing between crops.
- Keep critical spares such as paddles, couplings and bearings on hand during the crop, when an aerator failure is most costly.

What is a paddle wheel aerator used for?
It is used in aquaculture ponds to raise dissolved oxygen and circulate water. The motor-driven paddles splash water into the air, where it absorbs oxygen, and create a current that spreads oxygen-rich water across the pond. This supports healthy growth of shrimp, prawns and fish, especially at night and at high stocking densities.
How many HP of aeration does a shrimp pond need?
A common rule of thumb is about 1 HP of paddle wheel aeration for every 400 to 500 kg of expected shrimp harvest. A pond planned for 4 tonnes would therefore need around 8 to 10 HP, spread across several units. Actual needs vary with feed, temperature and water quality, so monitor dissolved oxygen.
Are paddle wheel aerators suitable for salt water?
Yes, provided they are built from corrosion-resistant materials. Our aerators use 304 stainless steel for the frame, driveshaft and hardware, which suits fresh, brackish and salt water. Rinsing salt deposits off between crops helps extend service life.
Where should aerators be placed in a pond?
Place them near the pond edges, angled so that all units push water in the same direction to form one circular current. This spreads oxygen evenly and gathers sludge in the centre, away from feeding areas. Avoid placing aerators where they work against each other or stir up the bottom too strongly.
What is the difference between a 4-paddle and a 6-paddle aerator?
A 6-paddle aerator has more paddle wheels and usually a larger motor, so it moves more water and transfers more oxygen per unit. It suits large or intensive ponds. A 4-paddle aerator is lighter and lower in cost, suiting smaller ponds or supplementary aeration.
Do you supply spare parts for paddle wheel aerators?
Yes. We supply paddle wheel aerators and their spares. Send the aerator model and the parts you need, and we will confirm availability with a quotation.
