Demonstration of recirculating system for the production of tilapia, leafy salad greens, kang kong and live bearing aquarium fish. The system is based on six 1,600 gallon tanks for tilapia in a green water culture system, with phytoplankton and “Bio-floc” for biological filtration. Water from these tanks is circulated through two filtration troughs in which kang kong and leafy salad greens are grown. These plants filter sediments, consume the nutrients from the fish waste, and provide an additional income stream for the system. Small aquarium fish are grown in the troughs to control mosquitoes, and sold to pet stores.
Tank-based recirculating aquaculture systems are used from tilapia production on many tropical islands where environmental constrants prevent prevent tilapia production in ponds. These sytems are resource intensive. One method to increase the profits from these systems is to incorporate additional enterprises into the system. This project brings additional income streams into the system by using an aquaponic component (leafy greens, and Kang kong) as its biological and chemical filtration system and by raising live bearing aquarium fish in these filters in addition to the Tilapia in the primary tanks.
