A prototype pond water management system (dissolved oxygen, pH and temperature) for giant freshwater prawn farming in Pak Phanang, Southern Thailand.

Significant income was promised by giant freshwater prawn farming, which served as a key occupation for farmers. However, challenges were faced by traditional methods, including difficulties in selling prawns of incorrect sizes, limited market demand, low prices, and the risk of waterborne diseases. In pond-raised environments, these prawns were prone to diseases due to deteriorating environmental conditions, particularly poor pond bottoms, resulting in unsuitable water quality and vulnerability in prawn growth.
