Internet of Things for Aquaculture in Smart Crab Farming

Abstract

Internet of Things (IoT) has been introduced and applied in many applications and become an emerging technology in digital era. The major economic in southern part of Thailand is aquaculture such as fishery, shrimp, pearl or crab farm. The concept of IoT connecting sensors and gathering all necessary data to IoT platform allows us to compute, control and manage farm more efficiently. Soft shell crab is very popular dishes in traditional Chinese and Asian fusion menu. Unfortunately, the productivity of typical soft shell crab farm is very small due to a low survival rate. In order to increase the productivities of soft-shell crab, the smart aquaculture system based on IoT is proposed. Each small crab has been raised separately in a small box. Normally, farmer feeds them one by one and monitors them every 4 hours in order to avoid soft shell crab turn to hard shell. In this thesis, thus, we propose to apply IoT and intelligent system to improve the productivity in soft shell crab farm. Water quality sensors, motion sensors and feeding system are designed and developed to enhance the capability of soft-shell crab farm by less people. The return of investment of our proposed IoT aquaculture is 36 months. Meanwhile, with the same concept, our system can be applied in another aquaculture to be smarter farm and be precision aquaculture in the near future
