This book was released on 2011 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: A considerable quantity of data and information were collected on many aspects of the systems of the three reservoirs, including hydrological, biophysical and limnological features, primary production, and fish and fisheries data. This information was condensed and synthesized with the aim of providing a baseline against which the ecological changes that have taken place since impoundment can be described and analysed. Efforts are made to explain changes in fish catch in relation to climatic variations, ecological succession and fishing effort. The review shows that biological data and information are generally available. However, as is also common elsewhere, all three cases suffer from the general tendency to isolate and compartmentalize research into separate disciplines.

Download or read book Post harvest Losses in Small scale Fisheries written by Gbola Akande and published by . This book was released on 2010 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The programme provided capacity building for fishery officers in qualitative and quantitative fish loss assessments methods, planned support, and supervised the implementation of loss assessment studies in five sub-Saharan African countries (Ghana, Kenya, Mali, United Republic of Tanzania and Uganda). Data were generated on quality and physical losses - the main types of losses identified - and quantified by researchers using three assessment methods. The fieldwork indicates that post-harvest fish losses in small-scale fisheries occur at all stages in the fish supply chain from capture to consumer. Huge physical and quality losses were found to occur in some supply chains assessed in all the countries, with quality losses reported to account for more than 70 percent of total losses.

Available in PDF, EPUB and Kindle. Book excerpt: Co-published with the Food and Agriculture Organization of the United Nations. Fisheries management is the process that has evolved to try to ensure that fisheries operate in a manner that provides the immediate benefits in a sustainable manner. The widely accepted goal is that the full range of benefits should not only be available for this generation but for generations to come. Fisheries management has been successful in some cases but there have also been many, many cases of failure. This volume is intended to contribute to improving this unsatisfactory state by addressing the widespread need for information and guidance on the broad and often complex task of fisheries management. It is an updated and expanded edition of the first version of "A fishery manager's guidebook" which was published as a FAO Fisheries Technical Paper in 2002. The major part of this new edition is divided into five parts intended to cover the range of concerns, tools and techniques essential to the modern fisheries manager, whether that manager is an individual or a formal or informal group. Following the Introduction: Part I examines the primary dimensions of fisheries: biological, ecological, social and economic Part II looks at the legal and institutional characteristics of fisheries Part III explores the tools that fishery managers have to achieve the objectives expected from a fishery Part IV discusses the role of scientific information of indicators and reference points Part V moves into implementation of fisheries management and includes a chapter on special considerations in small-scale fisheries This landmark publication is aimed at fishery managers and scientists. All libraries in research establishments and universities where fisheries and aquatic sciences are studied and taught will need copies of this important volume. Fisheries around the world make essential contributions to human well-being including the provision of basic food supplies, employment, recreational opportunities, foreign currency and others, providing benefits to hundreds of millions of people. Despite these benefits, our record of managing fisheries so that the benefits can be sustained has been poor, at best, and most fisheries around the world are experiencing serious ecological, social or economic problems and usually all three. Today there is global concern about the state of fishery resources and aquatic ecosystems, their resilience to future stresses such as climate change and their ability to continue to provide benefits.
Download or read book Geographical Information Systems written by Geoffery J. Meaden and published by Food & Agriculture Org.. This book was released on 1996 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The late 20th century has witnessed increasing crises in the world's marine fisheries. A causal analysis of these reveals that a common element are various manifestations of spatial inequity. This most frequently includes the inequity of access rights to the resource, but factors such as variations in resource depletion, spatio-temporal variations in stock recruitment, the imposition of regulatory zoning, destruction of marine ecosystems and the siting of mariculture facilities are other examples. To resolve some of these problems, management practices must be improved. As has been shown in other fields where spatially related problems occur, there is now a promising tool, Geographical Information Systems (GIS), which, combined with other analytical tools and models, could allow for improved spatial management. GIS are basically integrated computer based systems which allow for the input of digital geo-referenced data to produce maps plus other textual, graphical and tabular output. The essential usefulness of GIS however, lies in its ability to manipulate data in a large number of ways and to perform various analytical functions so as to produce output which makes for more efficient decision making.As with many computer based systems, the key to GIS success lies in the acquisition of suitable data. The various means by which both primary and secondary data can be located, gathered, accessed and stored are described.
Download or read book Adaptive management of fisheries in response to climate change written by Bahri, T., Vasconcellos, M., Welch, D.J., Johnson, J., Perry, R.I., Ma, X. & Sharma, R. and published by Food & Agriculture Org.. This book was released on 2021-02-01 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report aims to accelerate climate change adaptation implementation in fisheries management throughout the world. It showcases how flexibility can be introduced in the fisheries management cycle in order to foster adaptation, strengthen the resilience of fisheries, reduce their vulnerability to climate change, and enable managers to respond in a timely manner to the projected changes in the dynamics of marine resources and ecosystems. The publication includes a set of good practices for climate-adaptive fisheries management that have proven their effectiveness and can be adapted to different contexts, providing a range of options for stakeholders including the fishing industry, fishery managers, policymakers and others involved in decision-making. These good practices were linked to one or more of the three common climate-related impacts on fisheries resources: distributional change; productivity change; and species composition change. Therefore, these three impacts can serve as practical entry points to guide decision-makers in identifying good practice adaptation measures suitable for their local contexts. These good practices are based upon transferable experiences and lessons learned from the thirteen case studies across the globe and hopefully will contribute to greater uptake and implementation of climate-adaptive fisheries management measures on the ground.
Download or read book Fisheries Bioeconomics written by J.C. Seijo and published by Daya Books. This book was released on 2001 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overutilization of fish stocks, the overcapitalization of fisheries, the removal of associated benefits to society and growing concern over the conservation of marine biodiversity have resulted in a line of fisheries research that is multidisciplinary, dynamic and precautionary in approach. All the biological, ecological and economic factors need to be analysed if the forces regulating the dynamics of a fishery are to be appraised. This publication looks at the assumptions underlying the optimal allocation of renewable natural resources; lists the bioeconomic points of reference resulting from analysis of fisheries is supposed conditions of equilibrium; analysis bioeconomic models according to ecological interdependence factors (such as competition and predation) and technological factors (such as competition between fleets with different fishing capacity); offers a time-series analysis of fisheries and estimates the level of optimal effort; proposes mathematical models applied to bioeconomic analysis to support fisheries management plans; refutes the assumption of uniform resource distribution, incorporating a spatial dimension in fisheries dynamics analysis; and expounds basic elements of decision-making theory and criteria that reflect different attitudes to risk aversion in fisheries management.
