Abstract:

Fishponds in aquaculture farms are usually located in remote areas, far from grid supply lines. Aeration of ponds for growing aquatic animals (e.g., fish) is required to prevent mortality and to intensify production, especially when feeding is practical, and in warm regions. Aeration systems with photovoltaic power supply may be the appropriate technology from an ecological and economic point of view. In addition, photovoltaic power is very suitable for remote developing regions, owing to its simplicity and low maintenance. The purpose of the present study was to demonstrate an aeration system using a paddle wheel connected to a permanent magnet DC motor, and powered by a photovoltaic power supply. The study was carried out on the coastal area in the center of Israel. The aeration system operated satisfactorily for the demonstration period of more than two years.
