Mentor: Maryam Shafahi* Shawn Blanco, Jeff Ruggiero, Ricardo Hernandez, Daniel Woolston, David Felzer, Hadasa Reyes, Roslina Hussin, Daniel Garcia Mechanical Engineering Department, California State Polytechnic University Pomona, CA 91768 Aquaponics is an eco-friendly system for food production utilizing aquaculture and hydroponics to cultivate fish and crop without soil. It is an inexpensive symbiotic cycle between the fish and plant. In an aquaponic system, fish waste (ammonia) is fed into the plant bed which acts as a bio-filter to produce nitrate which is essential to grow vegetation. The fresh new water is then returned to the fish enclosure to restart the cycle. A unique advantage of an aquaponic system is conserving water more effectively compared to traditional irrigation systems. Conservation of water is accomplished by recirculating water between the plant bed and the fish habitat continuously. Organic fertilization of plants using dissolved fish waste is the other benefit of aquaponics. Utilizing plants as a natural alternative to other filters, requires less monitoring of water quality. In our project, an aquaponics prototype was designed and built in Lyle Center for Regenerative Studies at California State Polytechnic University of Pomona. The fish water Ammonia, Nitrate and PH were monitored during winter 2013. The experience gained from design and operation of the micro-sized aquaponics system was utilized in design and development of a bigger aquaponics system which was funded by President’s Research, Scholarship, and Creative Activity grant from Cal Poly Pomona. Based on our data we were able to evaluate the system performance in different PH levels and mineral deficiency. The future purpose of our project is finding an optimized situation for the aquaponics system to produce food and save water more efficiently and eco-friendly.
