Design control system for eel fish (Anguilla spp.) water aquaculture based Fuzzy Logic: MATLAB based simulation approach

Eel fish (Anguilla spp.) is catadromous fish species that born in saltwater, then migrate into freshwater as juveniles were growing into adults before spawning in the ocean. In the cultivation of eels enlargement, there are several factors that affect the growth of eels, such as water salinity (salt content in water), temperature, Dissolved Oxygen, current speed, acidity, and quality of water (or the microbial content of contaminants). This work, focuses on control and monitoring of water quality for eel aquaculture, by using 3 sensors, i.e. temperature, acidity (pH), and Dissolved Oxygen (DO) and will be done by fuzzy logic algorithm. The output of the fuzzy logic controller is to decide the time interval of switches that run the blower and nano-mixing pump simultaneously to keep the eel fish aquaculture at the desired value for parameter temperature, pH, and Dissolved Oxygen.
