Abstract — In this paper a real time monitoring and controlling system for Fish hatchery is designed,developed and proposed. The pH, dissolved oxygen, salinity, temperature and water level are prominentparameters which are responsible for the sustained growth of fishes. Mainly hatcheries of fresh waterornamental fishes are concentrated. Dissolved Oxygen content is a highly important parameter which if not available in the required amount will affect the growth of fishes and even lead to death. Salt helps infighting disease, parasites and chemical poisoning. The pH is a key parameter that has to be maintainedbetween 6.0 and 8.0. Temperature is in turn another important parameter which affects the health of fishes as well as the pH value. The proposed system monitors and controls the above said parameters. Areal time video streaming unit is also incorporated into the system in order to have round the clocksurveillance of the farm. Web server is designed to host a portal and help the person in charge to monitorthe farm remotely.

Keywords- pH, Dissolved Oxygen, Salinity, Temperature, Water level, Portal, Web server.

I. INTRODUCTION

A fish hatchery is a facility designed to raise fish. It provides an optimum environment for fish to grow bymaintaining proper pH value, salinity, water temperature, oxygen levels, safety etc. In order to survive in freshwater, the fish needs a wide range of physiological adaptation in order to keep the ion concentration in their bodybalanced. Fresh water fishes require a salinity level 0-0.05%. The pH is a key parameter which affects the life of fishes and is best between pH 7.0 to 8.0. Fresh water has a natural pH range of 6.0 to 8.0. The small changes inthe value of pH make the life of fish highly stressful and toxic. Temperature is another key parameter thatinfluences the value of pH. At elevated temperatures the toxicity level increases which affect the fishes. Saltbeing a natural ingredient make the fishes feel home and defeats toxic chemicals and avoid fish poisoning. It alsohelps to gain energy due to illness and stress and hence helps in their metabolism. In an aquarium like atmospherethe density of fishes is very high. The dissolved oxygen content can be very easily go down and it makes ahazardous situation. The water has to be aerated to top-up the oxygen levels. One approach to resolve all theabove problems is to employ a sensor circuit which monitors the required parameters such as pH, dissolvedoxygen, temperature, salinity and water level.
