Aquaponia: uma alternativa para a agricultura urbana

Urban Farm DB summary

This report from Brazil describes aquaponics — a system combining fish farming and soil-free hydroponic plant cultivation, in which fish waste nourishes plants that in turn filter the water for the fish — through a literature review and an experimental simulation of an aquaponic setup with a physically separate fish tank and hydroponic unit connected by pumping. It states the system requires no removal of final filtration waste and less complex filtration than aquaculture, has lower pest losses and earlier harvests than soil-based gardens, and operates at low cost, and concludes it is a sustainable, economical food-production approach suited to both household and industrial scale.
