This book was released on 2005 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of alien species is a proven means to increase production and value from aquatic ecosystems. In the Mekong/Lanchang basin, alien species such as tilapia (Orechromis spp.) play an important role in providing cheap and readily available protein to rural and poor sectors. However, alien species are now recognized as one of the most significant threats to aquatic biodiversity. Several steps are necessary for effective use and control of alien species, but one of the most important was identified to be following codes of practice similar to that developed by the International Council for the Exploration of the Sea.

This book was released on 2022-03-02 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Expert Consultation on the Development of the Sustainable Aquaculture Guidelines was held in Rome, Italy from 17 to 20 June 2019 to come out with a proposal for developing the Sustainable Aquaculture Guidelines to be presented in August 2019 at the tenth session of the Sub-Committee on Aquaculture of the Committee on Fisheries (COFI). The specific objectives of this Expert Consultation were to propose criteria for selecting case studies aimed at providing lessons learned for the development of the Sustainable Aquaculture Guidelines, and methodologies for documenting the case studies, for analysing the case studies to identify the lessons learned, and for developing the Sustainable Aquaculture Guidelines by also making use of existing guidelines. The consultation was attended by 15 experts, one resource person and FAO staff. The consultation was organized into both plenary and group discussions. The Experts agreed on a proposed methodology for identifying and selecting the lessons learned from strategies and experiences of aquaculture development worldwide; a methodology for documenting and analysing the lessons learned; a list of thematic modules; a gap analysis between existing guidelines and needs for new ones, and; an updated roadmap for the development of the Sustainable Aquaculture Guidelines.

Download or read book The State of the World s Aquatic Genetic Resources for Food and Agriculture written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-07-24 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conservation, sustainable use and development of aquatic genetic resources (AqGR) is critical to the future supply of fish. The State of the World’s Aquatic Genetic Resources for Food and Agriculture is the first ever global assessment of these resources, with the scope of this first Report being limited to cultured AqGR and their wild relatives, within national jurisdiction. The Report draws on 92 reports from FAO member countries and five specially commissioned thematic background studies. The reporting countries are responsible for 96 percent of global aquaculture production. The Report sets the context with a review of the state of world’s aquaculture and fisheries and includes overviews of the uses and exchanges of AqGR, the drivers and trends impacting AqGR and the extent of ex situ and in situ conservation efforts. The Report also investigates the roles of stakeholders in AqGR and the levels of activity in research, education, training and extension, and reviews national policies and the levels of regional and international cooperation on AqGR. Finally, needs and challenges are assessed in the context of the findings from the data collected from the countries. The Report represents a snapshot of the present status of AqGR and forms a valuable technical reference document, particularly where it presents standardized key terminology and concepts.
Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Download or read book Tropical Deltas and Coastal Zones written by Chu T. Hoanh and published by CABI. This book was released on 2010 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal deltas represent one of the most diverse biophysical regions in the tropical developing world. These regions are also home to large human populations and are significant areas of agricultural production and industrialization. Tropical deltas currently face a number of environmental pressures stemming from their intensive use and rapid development, and new threts are emerging as a result of global climate change and expected sea-level rise. Focusing on the developing countries of Asia, Africa and South America, chapters explore the impact of development strategies and existing land and water management practices on delta environments. New management techniques are also explored, which address conflicts between rice-based agriculture, aquaculture, fisheries, and the emerging threat of climate change. Illustrating the current key management challenges involved in protecting tropical deltaic systems in the face of environmental change, this book will be an essential reference for students, researchers and policy makers in agriculture, environmental science and aquaculture.

Download or read book Risk analysis in aquaculture written by Lind, C.E. and published by WorldFish. This book was released on 2015-04-07 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is based on materials covered and outputs generated during the Workshop on Risk Assessment Methodologies and Tools for Aquaculture in Sub-Saharan Africa, which was jointly held by WorldFish and FAO in Siavonga, Zambia on 28 June - 2 July 2010. The workshop was delivered as a training exercise to 17 participants from seven sub-Saharan countries and was designed to highlight current methodologies and tools available for environmental risk analysis in aquaculture development. A key focus of the workshop was to encourage participants to consider hypothetical but realistic scenarios and to discuss issues relevant to evaluating the environmental risks of a given activity or scenario. This publication presents selected scenarios from the workshop and the outcomes of the deliberative process as developed by the participants. This publication is factual but not comprehensive, therefore any statements or estimations of risk do not represent the actual risks arising from the described scenario. It is intended to serve as an easily readable introduction to risk analysis, highlighting worked examples that will provide guidance on how a risk analysis may be approached in a similar situation.ÿ

Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.
Download or read book Review of the state of the world fishery resources Inland fisheries written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-11-05 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: The FAO Fishery and Aquaculture Circular C942 Revision 3 (C942 Rev. 3) updates and expands the scope of previous revisions of the circular. C942 Rev. 3 is an important baseline document, intended to assist in the global understanding of inland fisheries and inform dialogue on their current and future role. The third revision reviews the status and trends of inland fisheries catch at global, continental and subcontinental levels. It places inland capture fisheries in the context of overall global fish production, and calls attention to the importance of inland capture fisheries with respect to food security and nutrition and the Sustainable Development Goals. It quantifies global inland fisheries resources in terms of food production, nutrition, employment, economic contribution with respect to those countries/regions or subnational areas where they are important. A characterization approach to distinguish large-scale and small-scale fishing operations and their relative contributions is provided. The review provides estimated economic values of inland fisheries, as well as a valuation of potential replacement cost of these (in terms of dollars, other resources such as land and water, feeds). There is also an analysis of the extent and economic value of recreational inland fisheries. The contribution to employment and the gender differences related to this are quantified. The linkages between inland fisheries and biodiversity are also explored. C942 Rev. 3 discusses ways to measure and assess inland fisheries, in particular, how to establish more accurately inland fishery catches in the many situations where there are challenges to collection of catch statistics.
