The Johns Hopkins Center for a Livable Future
Aquaponics Project at the Cylburn Arboretum
Demonstrating a sustainable food production system
The Johns Hopkins Center for a Livable Future (CLF) developed this project to demonstrate the capacity of aquaponics for raising edible plants and fish in a way that is economically viable and ecologically sound. The project affords CLF the opportunity to study this method of food production and serves as an educational resource to advance more sustainable food production methods and engage food system leaders throughout the region.
What is Aquaponics?Aquaponics combines aquaculture (fish farming) and hydroponics (soilless plant farming). Water is continuously recycled among the various components, flowing from the fish tanks, to the waste treatment tanks, to the plant growth tanks, then back to the fish tanks. This recirculation capitalizes on the mutually beneficial (symbiotic) relationships among three components–fish, beneficial bacteria, and plants.
- Fish are raised on healthy vegetarian feed.
- Bacteria convert fish waste into nutrients necessary for growth.
- Plants serve as a biofilter, purifying the water before it is returned to the fish tanks.
SupportThis project is made possible by a grant from the GRACE Communications Foundation and the generous support of the Baltimore City Department of Recreation and Parks, which has provided greenhouse space and technical assistance.
ToursThe demonstration project is open every Wednesday from 10am - noon for individual drop in visitors.
