Abstract:

Penaeus vannamei cultured in pond has more stringent requirements for water quality, the increase of unconsumed feeding and biological waste will consume a lot of water dissolved oxygen, break the water dynamic balance and lead to the increase of toxic ingredients, such as NH₃-N and NO₂-N, which can cause disease and even death of Penaeus vannamei, result in farmers’ economic loss and hinder the healthy development of aquaculture industry. Aiming at the above problems, we developed an intelligent water quality control system for Penaeus vannamei cultured in pond, which could monitor the water quality in real time and control the aerator, pump and other breeding equipment according to the growth habit of Penaeus vannamei. The system has the characteristics of intelligent control, reliable operation and high integration, which has achieved good results in the breeding production test, and could guarantee a safe breeding process, and effectively reduce the breeding risk of Penaeus vannamei cultured in pond.
