This open access book, written by world experts in aquaponics and related technologies, provides the authoritative and comprehensive overview of the key aquaculture and hydroponic and other integrated systems, socio-economic and environmental aspects. Aquaponic systems, which combine aquaculture and vegetable food production offer alternative technology solutions for a world that is increasingly under stress through population growth, urbanisation, water shortages, land and soil degradation, environmental pollution, world hunger and climate change.

“I have always wanted to figure out how to do sustainable aquaculture in the context of my home garden. Finally I’ve got the book to help me do it.” —Paul Greenberg, New York Times–bestselling author, Four Fish: The Future of the Last Wild Food Aquaponics is a revolutionary system for growing plants by fertilizing them with the waste water from fish in a sustainable closed system. A combination of the best of aquaculture and hydroponics, aquaponic gardening is an amazingly productive way to grow organic vegetables, greens, herbs and fruits, while providing the added benefits of fresh fish as a safe, healthy source of protein. On a larger scale, it is a key solution to mitigating food insecurity, climate change, groundwater pollution and the impacts of overfishing on our oceans. Aquaponic Gardening is the definitive do-it-yourself home manual, focused on giving you all the tools you need to create your own aquaponic system and enjoy healthy, safe, fresh and delicious food all year round. Starting with an overview of the theory, benefits and potential of aquaponics, the book goes on to explain: System location considerations and hardware components The living elements—fish, plants, bacteria, and worms Putting it all together—starting and maintaining a healthy system. Aquaponics systems are completely organic. They are four to six times more productive and use 90 percent less water than conventional gardens. Other advantages include no weeds, fewer pests, and no watering, fertilizing, bending, digging, or heavy lifting—in fact, there really is no down side! Anyone interested in taking the next step towards self-sufficiency will be fascinated by this practical, accessible and well-illustrated guide. “An excellent primer for anyone considering home-scale aquaculture.” —Peter Bane, publisher, Permaculture Activist and author, The Permaculture Handbook

Profitable cold-water fish and vegetable production. Join the aquaponic farming revolution! Built around a proven 120' greenhouse system operable by one person, The Aquaponic Farmer is the game changer that distills vast experience and complete step-by-step guidance for starting and running a cold-water aquaponic farming business—raising fish and vegetables together commercially. Coverage includes: A primer on cold-water aquaponics Pros and cons of different systems Complete design and construction of a Deep Water Culture system Recommended and optional equipment and tools System management, standard operating procedures, and maintenance checklists Maximizing fish and veg production Strategies for successful sales and marketing of fish and plants. As the only comprehensive commercial cold-water resource, The Aquaponic Farmer is essential for farmers contemplating the aquaponics market, aquaponic gardeners looking to go commercial, and anyone focused on high quality food production. Aquaponic farming is the most promising innovation for a sustainable, profitable, localized food system. Until now, systems have largely focussed on warm-water fish such as tilapia. A lack of reliable information for raising fish and vegetables in the cool climates of North America and Europe has been a major stumbling block. The Aquaponic Farmer is the toolkit you need.

Aquaponic gardening is a great method for raising fish and vegetables together. Aquaponic farming is a sustainable and commercially profitable way of organic farming. The waste of the fish will get converted by bacteria to nitrates, which the plants will feed on. It’s a closed loop system. In the beginning you need to test your water frequently but after a few weeks, it doesn’t need much maintenance anymore. The fish waste will almost create all the nutrients except a few which you will have to add yourself.

This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourcing for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication discusses in detail the three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It also presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting local and sustainable sources of aquaponic inputs. The publication also includes nine appendixes that present other key topics: ideal conditions for common plants grown in aquaponics; chemical and biological controls of common pests and diseases including a compatible planting guide; common fish diseases and related symptoms, causes and remedies; tools to calculate the ammonia produced and biofiltration media required for a certain fish stocking density and amount of fish feed added; production of homemade fish feed; guidelines and considerations for establishing aquaponic units; a cost-benefit analysis of a small-scale, media bed aquaponic unit; a comprehensive guide to building small-scale versions of each of the three aquaponic methods; and a brief summary of this publication designed as a supplemental handout for outreach, extension and education.
