Book (series)Small-scale aquaponic food production – Integrated fish and plant farming 2014This 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 sourci ng 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 fo r 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.

Book (stand-alone)Small Ponds Make a Big Difference: Integrating Fish with Crop and Livestock Farming 2000SINCE THE 1970s, global aquaculture production has grown rapidly and is now among the fastest growing food production sectors in many countries. Although Asia is by far the leading region with about 90 percent of aquaculture production, the importance of aquaculture is growing in Latin America and Africa. However, in relation to the potential for its development in these regions, aquaculture production is still marginal. Introducing aquaculture ponds in farming systems can improve th e economic and ecological sustainability of resource-poor farms. Potential benefits from integrating aquaculture in smallholder farming systems include: . enhanced rural employment and income through additional or off-season production; . improved food security; . increased availability of high-value protein food; . decreased risk through diversification; . improved water availability and nutrient recycling; . environmental benefits through enhanced resource flows. Despite it s potential, aquaculture is an often neglected option in agricultural development. Planners and senior agricultural research and extension officers often lack the information to identify opportunities for aquaculture development and to evaluate its feasibility under specific conditions. Traditionally, aquaculture research and extension is handled by specialized institutions, operating independently from crop and livestock institutions. Successful introduction, however, requires polic y-makers and planners to take sufficient account of diverse and often location specific social, economic, cultural and environmental conditions in traditional farming systems. As a joint effort of aquaculture and farming systems specialists, this book is designed for policy-makers in agriculture with no or little prior exposure to aquaculture. Its main focus is on extensive to semi-intensive small-scale pond aquaculture in developing countries. The main objective is to create awareness about the prerequisites and potential contributions of aquaculture in various farming systems. The book provides many examples of success and lessons learnt, and points out key considerations that are crucial to achieving the successful integration of aquaculture and agriculture on smallholder farms around the world. It is hoped that this publication will not only increase awareness about the role of aquaculture in farming systems development but also stimulate further collaboration among aquaculture and farming systems specialists and institutions, leading to enhanced support to and development of efficient farming systems in developing countries.
