Aquaponics — Integration of Hydroponics with Aquaculture

  1. 1. Aquaponics—Integration of Hydroponics with Aquaculture A Publication of ATTRA—National Sustainable Agriculture Information Service • 1-800-346-9140 • www.attra.ncat.orgBy Steve Diver Aquaponics is a bio-integrated system that links recirculating aquaculture with hydroponicNCAT Agriculture vegetable, flower, and/or herb production. Recent advances by researchers and growers alikeSpecialist have turned aquaponics into a working model of sustainable food production.
