Aquaponics is a method of growing fish and vegetables in a simple recirculating system. This book is designed and written to provide basic information and direction for people interested in building a backyard aquaponics system. It is NOT a "how-to" manual listing parts and with step-by-step procedures, but it's more like a conversation that you might have with a good friend about how he built his system. It is written to be easily understandable and includes lots of pictures and graphics. NOTE: This 5.5"x8.5" version contains the same information as the first edition however the physical size has been substantially reduced.
