Interest in linking intensive, closed system fish culture with hydroponic vegetable production continues to expand, particularly in cool temperature climates where greenhouse food production can provide year-round sustained yields of fresh produce. A newly revised design has overcome a number of the problems in previously tested systems when proven chemical hydroponic designs were combined with intensive fish culture systems. The success in the new design has resulted in solving the difficulties associated with the build-up of organic solids and the development of anaerobic conditions around the root systems of the vegetable produce. It further eliminates the need for the addition of separate biofiltration, water clarification components, and/or the plumbing required to connect system components together. ...
