Choosing a Shrimp Farming Aerator

A shrimp farming aerator is a device that helps provide oxygen to aquaculture ponds. Aerators come in many forms, including paddlewheel aerators, propeller-aspirator-pump aerators, diffused aerators, and aerators driven by an engine. These devices are primarily used to keep the water in the ponds free from harmful bacteria and chemicals. Aeration of the water is also necessary to maintain the dissolved oxygen level (DO), which is essential for sustaining the physiological processes of shrimp. Generally, aerators should be operated 24 hours a day.

Traditionally, aerators in shrimp ponds use a large power source to operate. However, aerators that have been developed with advanced technological features can reduce the overall energy requirements. These aerators can be controlled remotely, which means farmers can monitor and control aerator functions from their homes. Aerator manufacturers should redesign their aerators to improve efficiency and reduce power consumption.

In Asia, there are several types of floating aerators that farmers use in their shrimp ponds. These include long-arm aerators and paddlewheel aerators. These aerators are powered by 2- to 5-hp electric motors. They are commonly assembled by the farmer. Some of these aerators are built by aerator manufacturers and sold as prefabricated units.

In some countries, short-arm aerators are also used. In Indonesia, farmers have learned to use refurbished auto transmission motors to drive these devices. These motors are less efficient than the ones that are made by factory manufacturers. This inefficiency is caused by a low brake power to wire power ratio. Therefore, aerator manufacturers should develop more efficient paddles for these devices.

Although aerators in shrimp ponds are important, they are not the only factors that contribute to the quality of shrimp farmers' production. The quality of the water is another factor. The water should be free from contaminants and not contain fish or amphibians. Lastly, the DO level in the ponds is a good indicator of aeration performance. Using this information to choose an aerator can help improve the productivity of farmers.

The energy used for aerating a tonne of shrimp should not exceed 15 GJ/t. To achieve this, aeration should be staged to minimize its impact on shrimp growth. This practice should be implemented by modern farmers. The aeration capacity of the aerator should increase with the biomass of the shrimp. During the first two-thirds of the grow-out period, the proportion of installed aerator capacity that is used in shrimp farms often exceeds the aeration needs of the shrimp. This may be a result of farmers' desire to protect against low dissolved oxygen levels.
