Book Description
Academic Paper from the year 2021 in the subject Agrarian Studies, grade: 3.84, , language: English, abstract: This paper is a retrospective review of Carp Polyculture in Nepal. Polyculture is an art and science of growing two or more compatible fish species in a pond to maximize production by taking advantage of different spatial distribution and feeding habits. Polyculture concepts rely on the complete utilization of various spatial niches and trophic of a pond to acquire a maximum production per unit area. Carp polyculture is the most common, popular, and successful aquaculture system in Nepal. Carp polyculture is the major aquaculture system contributing to more than 90% of total aquaculture production in Nepal. In 2018/19, total fish production, aquaculture, and productivity were 91,832 t, 70,832 t, and 4.92 t/ha, respectively, which is insufficient to fulfill the growing demand for fish in Nepal. Therefore, it is essential to increase production and productivity.

Book Description
An overview of the current scientific knowledge available on climate change implications for fisheries and aquaculture is provided through three technical papers that were presented and discussed during the Expert Workshop on Climate Change Implications for Fisheries and Aquaculture (Rome, 7-9 April 2008). A summary of the workshop outcomes as well as key messages on impacts of climate change on aquatic ecosystems and on fisheries- and aquaculture-based livelihoods are provided in the introduction of this Technical Paper. The first paper reviews the physical and ecological impacts of climate change relevant to marine and inland capture fisheries and aquaculture. The paper begins with a review of the physical impacts of climate change on marine and freshwater systems and then connects these changes with observed effects on fish production processes. It also outlines a series of scenarios of climate change impacts on fish production and ecosystems through case studies in different regions and ecosystems. The second paper tackles the consequences of climate change impacts on fisheries and their dependent communities. It analyses the exposure, sensitivity and vulnerability of fisheries to climate change and presents examples of adaptive mechanisms currently used in the sector. The contribution of fisheries to greenhouse gas emissions is addressed and examples of mitigation strategies are given. The role of public policy and institutions in promoting climate change adaptation and mitigation is also explored. Finally, the third paper addresses the impacts of climate change on aquaculture. It provides an overview of the current food fish and aquaculture production and a synthesis of existing studies on climate change effects on aquaculture and fisheries. The paper focuses on the direct and indirect impacts of climate change on aquaculture, in terms of biodiversity, fish disease and fishmeal. Contribution of aquaculture to climate change is addressed (carbon emission and carbon sequestration), as well as possible adaptation and mitigation measures that could be implemented.

Book Description
The Global Conference on Aquaculture 2010 brought together a wide range of experts and important stakeholders and reviewed the present status and trends in aquaculture development, evaluated the progress made in the implementation of the 2000 Bangkok Declaration and Strategy, addressed emerging issues relevant to aquaculture development, assessed opportunities and challenges for future aquaculture development and built consensus on advancing aquaculture as a global, sustainable and competitive food production sector. This volume, yet another joint effort of FAO and NACA, brings the outcome of the Global Conference on Aquaculture 2010, the much-needed clear and comprehensive technical information on how aquaculture could be mobilized to alleviate global poverty and improve food and nutrition security in the coming decades.

Book Description
The implications of biodiversity loss for the global environment have been widely discussed, but only recently has attention been paid to its direct and serious effects on human health. Biodiversity loss affects the spread of human diseases, causes a loss of medical models, diminishes the supplies of raw materials for drug discovery and biotechnology, and threatens food production and water quality. Biodiversity and Human Health brings together leading thinkers on the global environment and biomedicine to explore the human health consequences of the loss of biological diversity. Based on a two-day conference sponsored by the National Institutes of Health, the National Science Foundation, and the Smithsonian Institution, the book opens a dialogue among experts from the fields of public health, biology, epidemiology, botany, ecology, demography, and pharmacology on this vital but often neglected concern. Contributors discuss the uses and significance of biodiversity to the practice of medicine today, and develop strategies for conservation of these critical resources. Topics examined include: the causes and consequences of biodiversity loss emerging infectious diseases and the loss of biodiversity the significance and use of both prescription and herbal biodiversity-derived remedies indigenous and local peoples and their health care systems sustainable use of biodiversity for medicine an agenda for the future In addition to the editors, contributors include Anthony Artuso, Byron Bailey, Jensa Bell, Bhaswati Bhattacharya, Michael Boyd, Mary S. Campbell, Eric Chivian, Paul Cox, Gordon Cragg, Andrew Dobson, Kate Duffy-Mazan, Robert Engelman, Paul Epstein, Alexandra S. Fairfield, John Grupenhoff, Daniel Janzen, Catherine A. Laughin, Katy Moran, Robert McCaleb, Thomas Mays, David Newman, Charles Peters, Walter Reid, and John Vandermeer. The book provides a common framework for physicians and biomedical researchers who wish to learn more about environmental concerns, and for members of the environmental community who desire a greater understanding of biomedical issues.

Book Description
The zebrafish (Danio rerio) is a valuable and common model for researchers working in the fields of genetics, oncology and developmental sciences. This full-color atlas will aid experimental design and interpretation in these areas by providing a fundamental understanding of zebrafish anatomy. Over 150 photomicrographs are included and can be used for direct comparison with histological slides, allowing quick and accurate identification of the anatomic structures of interest. Hematoxylin and eosin stained longitudinal and transverse sections demonstrate gross anatomic relationships and illustrate the microscopic anatomy of major organs. Unlike much of the current literature, this book is focused exclusively on the zebrafish, eliminating the need for researchers to exclude structures that are only found in other fish.

Book Description
This document contains nine FAO commissioned papers on cage aquaculture including a global overview, one country review for China, and seven regional reviews for Asia (excluding China), northern Europe, the Mediterranean, sub-Saharan Africa, Latin America and the Caribbean, northern America and Oceania. The content of the papers is based on the broad experience and sound knowledge of the authors with advice and help received from many experts and reviewers around the globe. The papers were presented to a distinguished audience of some 300 participants from over 25 countries during the FAO Special Session on Cage Aquaculture - Regional Reviews and Global Overview at the Asian Fisheries Society (AFS) Second International Symposium on Cage Aquaculture in Asia (CAA2), held in Hangzhou, China, from 3 to 8 July 2006.
