We propose a method for estimating the condition of farmed shrimp in Recycling Aquaculture System (RAS) tank using CPS (Cyber Physical System). In this proposal, the amount of dissolved oxygen (DO, Dissolved Oxygen) is measured by an IoT devices installed in the tank, and the state of farmed shrimp in the tank is estimated from the change in DO. In order to confirm the condition of cultured shrimp, existing methods often estimate from images, but it is difficult to apply in a turbid water tanks. On the other hand, the proposed method uses the measured values of DO, so it can be applied even in turbid water tanks. We constructed this proposed method as a CPS and confirmed that the shrimp activity can be estimated.
