Small-Scale Aquaponic Food Production Book

smallscaleaquaponics

Excellent free ebook (technical paper) I found when searching around yesterday, looks like a wealth of info to tap into for those wishing to test out the benifits of Aquaponics. For those who don’t know is a symbiotic integration of two disciplines: aquaculture and hydroponics. A symbiotic relationship between plant and fish, the waste from the fish feeds the plants and the plants in turn clean the water for the fish.

The growing technique is excellent for those hoping to avoid lots of expensive chemicals, it’s also a labour-saving technique too. In times of dwindling supplies of water and arable land worldwide this production system can really help us reduce water consumption on food production and enhance our food security.

The book discusses three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting the advantages and disadvantages of this method of food production. The publication discusses the main theoretical concepts of aquaponics, including the nitrogen cycle, the role of bacteria, and the concept of balancing an aquaponic unit. It considers water quality, testing and 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.
