Available in PDF, EPUB and Kindle. Book excerpt: Tilapia Feed - Duckweed is a tiny aquatic plant covering stagnant water bodies; it's seen in channels and waterways in semi-tropical and tropical climates in most countries. The green, three rounds fronds plant, or any of its four genera is known to many people who have seen it without realizing such aquatic plant is Duckweed or that such an abundant microphyte plant, considered an invasive plant, offers a great potential as animal feed, specially for fish. Its high level of protein content makes it an ideal fish feed for Tilapia, Carp and possibly other fish as well with great potential savings as fish feed. Duckweeds have structural features that have been simplified by natural selection. A Duckweed leaf is flat and ovoid. Many species have adventitious roots which function as a stability organ and which tend to lengthen as mineral nutrients in water are exhausted. Compared with most plants, Duckweed leaves have little fiber (5% in dry matter of cultivated plants) as they do not need to support upright structures. As a result the plant has little or no indigestible material even for monogastric animals like fish. This contrasts with many crops such as soya beans, rice, or maize, where approximately 50% of the biomass is in the form of high fiber, and low digestibility residues. Their unique properties, such as their phenomenal growth rate, it doubles its size every twenty-four (24) hours or so, offers great potential savings for the animal grower. Its high protein content, its ability to clean wastewater and growth quickly even in brackish water, have been investigated and documented in the last ten years. This manual intends to propagate the value of Duckweed as a food alternative to animal growth, focusing this intent on fish farming, where its potential impact will be recognized immediately by a savvy fish farmers for many reasons discussed here. In the last two decades Duckweed has been investigated for commercial applications seeking to treat wastewater by American firms; mainly by the PRISM Group which pioneered Duckweed farming in India and Peru. Both investigative programs in South Asia and Latin America, suggested that Duckweed cropping would be important as a source of fish and poultry feed; additionally the investigation demonstrated the use of Duckweed as a wastewater treatment alternative. This Technical Study for Latin America and Asia was designed to put together relevant information on Duckweed farming, its beneficial uses and to make such information available to people worldwide. The information in this technical manual comes from many sources; the contribution of the staff at the experimental station in Bangladesh and its directors, Harinder S. Kohli and Mohammed Ikramullah, are acknowledged. Paul Skillicorn and William Spira of the PRISM Group, and William Journey. Viet Ngo of the Lemna Corporation and Richard Middleton of Kalbermatten Associates are given recognition here. Others recognized for this important technical work ar Grimshaw, Khouri, Leeuwrik, van Santen and Macoun. Professor Thomas Popma of the International Center for Aquaculture at Auburn University provided technical support.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hunger and malnutrition present serious complications for several areas all over the world. In 2012, about 25% of the world's children were classified as chronically malnourished; currently, almost one billion people go hungry every day (World Hunger Education Service, 2015). With a population forecast of 10 billion people in 2050, world hunger and malnutrition issues will become more severe and problematic (Worldometers.info, 2016). The finite amount of resources and space on Earth, in combination with the demands of a growing population, present an inevitable challenge that society must confront. That challenge resides in the production of basic needs (food, water, energy, shelter) for more people using fewer resources on Earth. Aquaponics, farming aquatic animals and growing crops in a single system, has been proposed by the United Nations as a potential solution to help feed the world (Somerville et al., 2014). Unfortunately, the relatively high cost and unsustainable practice of producing commercial fish feed from ocean-caught fish is currently inhibiting aquaponics from reaching its true potential (Naylor et al., 2000). A possible solution to this problem resides in the utilization of high-protein, plant-based feedstock to replace traditional fishmeal. Many omnivorous fish are known to eat aquatic plants. For example, Oreochromis niloticus (Nile tilapia), a fish commonly used in aquaculture (fish farming) systems, has been shown to feed on Lemna minor (duckweed) growing in slow-moving or stagnant water (Heuze & Tran, 2015). To provide a steady supply of duckweed for aquaponics systems year-round, it is necessary to harvest and dry the plant for extended storage. The goal of this research was to test the preference of Nile tilapia fingerlings for duckweed dried under different conditions to determine the best preparation for use in future pilot-scale aquaponics studies. The different duckweed drying methods tested in this study included: drying in an oven at 40 or 60° C, and drying in the sun. Utilizing Manly's [alpha] preference index, the results of six randomized feeding trials revealed that Nile tilapia fingerlings exhibit preference ([alpha] > 1/m; m = 3) for duckweed dried at 40° C and 60° C, and exhibit an avoidance ([alpha]

Download or read book Wastewater written by Pay Drechsel and published by Springer. This book was released on 2015-03-11 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: The books provides a timely analysis in support of a paradigm shift in the field of wastewater management, from ‘treatment for disposal’ to ‘treatment for reuse’ by offering a variety of value propositions for water, nutrient and energy recovery which can support cost savings, cost recovery, and profits, in a sector that traditionally relies on public funding. The book provides new insights into the economics of wastewater use, applicable to developed and developing countries striving to transform wastewater from an unpleasant liability to a valuable asset and recasting urbanization from a daunting challenge into a resource recovery opportunity. “It requires business thinking to transform septage and sewage into valuable products. A must read for water scholars, policy makers, practitioners, and entrepreneurs". Guy Hutton, Senior Economist, Water and Sanitation Program, Water Global Practice, World Bank “This book provides compelling evidence and real solutions for the new ‘resource from waste’ approach that is transforming sanitation, boosting livelihoods, and strengthening urban resilience”. Christopher Scott, Professor and Distinguished Scholar, University of Arizona “This book shows how innovative business thinking and partnerships around resource recovery and reuse fit well within an inclusive green economy and climate change adaptation and mitigation strategies”.

Download or read book The Duckweed Genomes written by Xuan Hieu Cao and published by Springer Nature. This book was released on 2020-01-07 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book tells the story behind the first Spirodela genome sequencing project. Further, it describes the current genomics applications of these findings, and efforts to sequence new genomes within the family. The closing chapters address the sequencing of the over 1 Gigabase Wolffia genomes, which could have major impacts on genome evolution and agricultural research. The duckweed or Lemnaceae family is a collection of 5 genera and 37 species of the smallest, fastest-growing flowering plants. Many of these aquatic monocotyledonous plants can grow all over the world, in a variety of climates. Given their simplified and neotenous morphology, duckweeds have been researched for several decades as a model species for plant physiology and ecotoxicological research, contributing to our understanding e.g. of flowering response, plant circadian systems, sulfur assimilation pathways and auxin biosynthesis. In addition, duckweed-based treatment has been a favorite and feasible means, especially in developing countries, of removing phosphorus and pharmaceutical chemicals from sewage and wastewater. With a dry annual mass yield per hectare of up to 80 tonnes (equivalent to 10 tonnes of protein), duckweed is also a promising aquatic crop in new modern and sustainable agriculture. Besides being an excellent primary or supplemental feedstock for the production of livestock and fish, duckweed biomass can be utilized as a potential resource for human nutrition, biofuel, or bioplastics, depending on water quality as well as protein or starch accumulating procedures. These academic and commercial interests have led to international efforts to sequence the Spirodela polyrhiza genome, the smallest and most ancient genome in the family.
Download or read book Integrated Livestock fish Farming Systems written by David Little and published by Food & Agriculture Org.. This book was released on 2003 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated farming in Asia is either considered an eco-friendly good that should be preserved for environmental reasons or a poor practice that will soon be superseded by industrial aquaculture. This report finds that most livestock-fish integration is sound business conducted by entrepreneurs accessing urban markets where the price of fish is relatively low. It can be used as part of a strategy to reduce environmental impacts of intensive livestock production and to produce low-cost food. Farmers have proved adept at both developing their systems to meet their own needs and diversifying the role of ponds, fish and livestock within their complex livelihoods.
Download or read book Small scale Aquaponic Food Production written by Christopher Somerville and published by Fao. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
