This is an aerator for aquaculture. It can be used in ponds or tanks to raise fish, shrimp, or mussels. This model uses a car axel and an electric motor. It rests on several long PVC tubes, which give it buoyancy.
As the axel turns and the paddles hit the water, the tool oxygenates the water, which improves the respiration of the organisms in the pond. Improved respiration means higher quantities of micro-plankton in the water, better nutrition for fish, and an overall improvement in the health of the ecosystem. In short, this device raises the productivity of an aquaculture.
