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, mud crab and so on. The concept of IoT which is about connecting the sensors and gathering all necessary data to cloud platform allowing us to compute, control measure, and manage farm efficiently. Soft shell crab is most important ingredient in Chinese, Japanese, and co-fusion menu requiring in many premium restaurants. Unfortunately, the productivity of soft-shell crab industry is very small due to a low survival rate in raising process and lacking of small crab. In tradition al soft-shell crab farm, each small crab has been grown separately of a small box in the old shrimp pond. Farmer has to feed them individually and monitor them every 4 hours in order to avoid soft-shell crab turns to hard shell. In this work, thus, we propose to apply IoT and intelligent system to improve the productivity in the traditional soft-shell crab farm. Water quality sensors, motion sensors, and feeding system are designed and developed to enhance the survival capability of soft-shell crab farm. Meanwhile, with the same concept, our system can be applied in another aquaculture to be smarter farm and be precision aquaculture in the southern path of Thailand.
