About the Workshop
Aquaponic systems are becoming increasingly popular, and more people are finding innovative ways to produce more than one crop in their recirculating systems. Aquaponic systems are recirculating aquaculture systems that incorporate the production of plants without soil. In typical recirculating aquaculture systems, the goal is to produce large quantities of aquatic biomass in small amounts of space and small volumes of water.
In such a system, waste products can accumulate if not physically removed or otherwise filtered via mechanical or biological means. The organic buildup and metabolic byproducts can be reused in aquaponic system by a secondary crop; plants. Plants can grow rapidly with dissolved nutrients that are excreted directly by the aquatic species or generated from the microbial breakdown of the animal waste by the various species of bacteria in the system. In closed recirculating systems with very little daily water exchange, dissolved nutrients accumulate in concentrations similar to those in hydroponic nutrient solutions. These dissolved waste nutrients are taken up by the plants, reducing wastewater discharge to the surrounding watershed and allowing for more efficient use of the fish feed.
