Available in PDF, EPUB and Kindle. Book excerpt: Primary productivity in the sea accounts for ~30% of the total global annual production. Holistic understanding of the factors determining marine productivity requires detailed knowl edge of algal physiology and of hydrodynamics. Traditionally studies of aquatic primary productivity have heen conducted hy workers in two major schools: experimental laboratory biology, and empirical field ecology. Here an attempt was made .to hring together people from both schools to share information and con cepts; each author was charged with reviewing his field of exoer tise. The scope of the Symposium is broad, which we feel is its strength. We gratefully acknowledge financial support from the Depart ment of Energy, the United States Environmental Protection Agency, the National Oceanic and Atmospheric Administration, including the NMFS Northeast Fisheries Center and the MESA New York Bight Project. Thanks are due to Mrs. Margaret Dienes, with out whose editorial skills this volume could not have been pro duced, and to Mrs. Helen Kondratuk as Symposium Coordinator. Finally, we wish to record our indebtedness to Dr. Alexander Hollaender for his tireless efforts and valuable advice in sup porting all aspects of this Symposium.

Available in PDF, EPUB and Kindle. Book excerpt: The period since World War II, and especially the last decade influenced by the International Biological Program, has seen enormous growth in research on the function of ecosystems. The same period has seen an exponential' rise in environmental problems including the capacity of the Earth to support man's population. The concern extends to man's effects on the "biosphere"-the film of living organisms on the Earth's surface that supports man. The common theme of ecologic research and environmental concerns is primary production the binding of sunlight energy into organic matter by plants that supports all life. Many results from the IBP remain to be synthesized, but enough data are available from that program and other research to develop a convincing sum mary of the primary production of the biosphere-the purpose of this book. The book had its origin in the parallel interests of the two editors and Gene E. Likens, which led them to prepare a symposium on the topic at the Second Biological Congress of the American Institute of Biological Sciences in Miami, Florida, October 24, 1971. Revisions of the papers presented at that symposium appear as Chapters 2, 8, 9, 10, and 15 in this book. We have added other chapters that complement this core; these include discussion and evaluation of methods for measuring productivity and regional production, current findings on tropical productivity, and models of primary productivity.

Available in PDF, EPUB and Kindle. Book excerpt: This book relates some fundamental aspects of biological oceanography and freshwater biology to global aspects of the future protein nutrition of man and to our understanding of the processes of evolution. Seasonal and other factors controlling organic productivity in temperate oceans are outlined, and more unusual trophic features are considered. Methods for future exploitation of the oceans--particularly through sea-farming--are discussed and critically assessed. The finite nature of the oceans' resources is stressed. Energetics of food chains, the dynamics of exploited fish stocks, and the biogeochemistry of organic cycles are clearly explained and examined.--

Download or read book Fundamentals of Aquatic Ecology written by R. S. K. Barnes and published by John Wiley & Sons. This book was released on 2009-07-21 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Aquatic Ecology is a completely updated and revised edition of the earlier work, Fundamentals of Aquatic Ecosystems. The new edition has been re-titled to reflect the fact that the authors found that, from the modification exercise, a completely different and new book emerged. The new edition concentrates heavily of the fundamental features common to all aquatic systems, both marine and freshwater. This unique synthesis allows for the discussion of ecological processes comparatively, across environments. A general introduction is followed by discussion of various 'types' of aquatic ecosystems - open waters, coastal zones, benthos, and the aquatic ecosystem as a whole. This is followed by an important new chapter on aquatic ecosystems and global ecology. Later chapters consider the individuals and communities in aquatic ecosystems. A totally re-written and rejuvenated edition of an established student text. Synthesizes both marine and freshwater ecology. Covers both ecosystem ecology and population biology. In depth consideration of man's impact on the aquatic environment.

This book was released on with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic agricultural systems (AAS) are food production systems in which the productivity of freshwater or coastal ecosystems contributes significantly to total household nutrition, food security, and income in developing countries. The Consultative Group of International Agricultural Research (CGIAR) engages in research in development to address this challenge. The goal of the CGIAR research program on Aquatic Agricultural Systems (referred to in this paper as “the AAS program”) is to harness the development potential of aquatic agricultural systems to improve the livelihood security and well-being of an estimated 10 million by 2016 poor people who are dependent on these systems This working paper draws lessons from the target countries through a review of productivity interventions such as modifying habitats, harnessing underutilized productive resources, improving the integration of production commodities, supporting community-based natural resource management, and genetically improving strains. In total, this paper reviewed 20 productivity interventions.

Download or read book Restoration of productive aquatic ecosystems by small scale fisheries and aquaculture communities in Asia written by Gardiner, N.M. and published by Food & Agriculture Org.. This book was released on 2022-04-06 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report showcases examples of actions taken by small-scale fishers and aquaculture farmers in Asia to restore the productivity of aquatic ecosystems. Small-scale fishers and fish farmers include some of the world’s most marginalized and impoverished people groups, yet their harvests account for over half of the world’s aquatic food production. The marine, coastal and freshwater ecosystems their livelihoods depend upon are degraded from human impacts and further at risk from climate change. Ecosystem restoration actions by fisherfolk communities can revitalize the socio-ecological services and sustain progress over time. Both passive and active restoration approaches are being employed across Asia’s marine, coastal and inland waterways. Fishers, fish farmers, and fishworkers’ restorative actions are focused on increasing the sustainability of their operations. Common approaches include eliminating destructive fishing, reducing overfishing through gear changes and effort control, restoring connectivity of floodplains and fish migration pathways, integrated aquaculture and rice-farming practices, re-stocking of native fisheries, and actively rehabilitating and / or re-establishing habitats. Progress is measurable through a diverse array of environmental, socio-economic and governance related metrics. Changes in fisheries catches, ecological connectivity, water quality, habitat diversity and structure, and fish consumption provide important measures of biodiversity gains (or losses). Common enablers of success include economic incentives, co-management and legal recognition of fishing rights, highly engaged fisherfolk cooperatives or community groups, women’s leadership and development, and community partnerships with stakeholders that focus on enabling fisherfolk’s own goals for sustainable livelihoods. Ecosystem restoration activities have not lasted when these enablers are insufficiently attended to and when environmental aspects of project feasibility, such as the choice of rehabilitation locations and / or species, are poorly planned. Successes in ecosystem restoration by fisherfolk can and are being scaled out to neighbouring communities and countries. Key to this is the sharing of stories, lessons learned and tools through south-south partnerships, learning exchanges, and women’s groups. Simple, low-cost tools and actions have enabled long-term engagement by small-scale fishers in sustainable operations. More complex actions, such as the uptake of integrated aquaculture systems, are also enabling stepwise changes in ecosystem restoration. By sharing stories from different ecosystems, fisheries, and geographies, this report seeks to help fisherfolk and their partners glean from one another and achieve faster progress in ecosystem restoration.
