One of the main feature of this system is the automatic aeration method, which was designed to reduce the high electrical energy consumption due to excessive use of the aeration system. As can be seen in Figure 7, the aeration system on a shrimppond usually consists of 8 rotary fans, and in most condition, all fans will be operated continuously during the aquaculture period. Thus the idea is to selectively operate the rotary fans, either partly or non-continuously, depending on the DO value of the water.
