Automated indoor Aquaponic cultivation technique

摘要

Aquaponic has become an interesting model for private sector, aquaculture and environmental scientist because of many advantages that can be obtained. The word ‘Aquaponic’ refer to the integration of ‘hydroponic’ (growing plant/vegetable production without soil) with aquaculture (fish farming). The growth performance of comet goldfish (aquatic) against a hydroponic plant of Ipomoea aquatic (water spinach), Spinacia oleracea (spinach) type of leafy vegetable and water plant were evaluated in recirculation of this Aquaponic system towards temperature, light and fish waste effectiveness. The fish were feed with commercial pelleted feeds containing 30% crude protein which can provide almost all nutrients required for the plant growth. Auto feeder place in this system used to maintain the growth and survival rates. Filter systems used to remove the amount of waste materials and breakdown products from the water. In this project, a set point is the desired value that needed by the user. The set point will be the desired water level, the monitored temperature in fish tank, the monitored temperature at plant area and the desired amount of food. While Arduino (Mega) function as a brain that used to receive the information from the sensor and come out with an instruction in term of response (action) as the feedback. Then the action will be based on the actuator that was reacted towards the act received. Therefore, this closed system was completed the project development system.
