Here swim tilapia in the Bertie Backus Urban Food Hub aquaponic system in Northeast Washington, DC. These tilapia are about 6 inches long and reside in one of the six 650-gallon tanks at the Backus system.
The water is very clear due to the use of a 100 micron “drum filter” and 50 micron “tank filter”.
Bertie Backus is one of four Urban Food Hubs constructed and operated by the University of the District of Columbia. UDC also operates aquaponic systems at the Van Ness, P.R. Harris College, and East Capitol Urban Farm food hubs.
The Van Ness aquaponic system was started earliest of the four. We first stocked fish in April, 2017. It’s been successfully growing basil, lettuces, and tomatoes with fish food as the ONLY nutritional input for about 6 months now. After working out initial kinks, water quality parameters are consistently excellent and the fish grow about an inch per month.
Anacostia Aquaponics worked with UDC during the initiation process of these systems from March through September, 2017. It was a great learning experience.
With appropriate management and resources, UDC’s Urban Food Hub aquaponic systems should continually improve and grow lots of fresh, healthy food for Washington, DC residents.
