I occasionally have a visitor to the farm and one of the first things they want to see is the aquaponics system. My farm is not strictly an aquaponics operation. The main purpose of the aquaponics system with our beautiful koi and goldfish is simply to show our customers additional alternatives to a traditional soil-based garden. What is Aquaponics? The first question many people ask me is "What is Aquaponics?". This is a great question that can be answered in many ways.
