Nelson and Pade, Inc. offers complete aquaponic systems, growing supplies, project planning and design services, training and workshops. In addition, Nelson and Pade, Inc. publishes the Aquaponics Journal, the book, Aquaponic Food Production, videos and school curriculums on aquaponics and hydroponics. They have earned industry-wide respect for their leadership and knowledge of aquaponics and controlled environment agriculture. Aquaponics is the combination of aquaculture and hydroponics. In aquaponics, you grow fish and plants together in one integrated, soilless system. The fish waste provides a food source for the plants and the plants provide a natural filter for the water the fish live in. Aquaponics produces safe, fresh, organic fish and vegetables. When aquaponics is combined with a controlled environment greenhouse, premium quality crops can be grown on a year-round basis, anywhere in the world. Aquaponics can be used to sustainably raise fresh fish and vegetables for a family, to feed a village or to generate a profit in a commercial farming venture.
