Available in PDF, EPUB and Kindle. Book excerpt: As traditional commercial fishing becomes increasingly expensive and restrictive, aquacultural fish production emerges as a practical viable alternative. The Aquaculture Sourcebook is an introductory text and ready reference for information on the fresh-, brackish-, and salt-water farming of both fish and shellfish, as well as of several important algae. Until now, such material has been available only in scattered publications; but the Aquaculture Sourcebook incorporates all the feasibility data pertinent to farming aquacultural species in North America into one easy-to-use text. It will be welcomed not only by current and future aquaculturists, but also by fisheries, seafood company managers, biologists, teachers, and students. The Aquaculture Sourcebook has been designed to satisfy the needs of fisheries, scientists, and commercial aquaculturists by providing, in a handy and well-organized format, information vital for successful North American aquacultural ventures. Concise details are given for over a hundred individual speices, including not only those raised for human consumption, but also organisms reared for feed, bait, or other purposes. Each entry in this valuable volume covers such relevant material as: *the scientific and common names of the organism *its visual appearance and distinctive characteristics *habitat range specifications *species reproduction and development *age- and growth-related factors *specific parasites an diseases *potential predators and/or competitive species *its prospects for future aquacultural success Key groups of closely related species are discussed in a geographical context, highlighting areas which each will find the habitat best for its survival. Great care has been taken to specify ranges of tolerable salinity and optimum temperature for candidate species, and emphasis has been placed on creating aquacultural environments that replicate those normally habitated in nature. Comprehensive, informative, and accessible to layperson and scientist alike, the Aqualculture Sourcebook is both the perfect desktop reference for anyone establishing an aquacultural facility, and a ready reference to help maintain one.

Download or read book Sustainable Land Management Sourcebook written by World Bank and published by World Bank Publications. This book was released on 2008-06-17 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Policies promoting pro-poor agricultural growth are the key to helping countries achieve the Millennium Development Goals especially the goal of halving poverty and hunger by 2015. The public sector, private sector, and civil society organizations are working to enhance productivity and competitiveness of the agricultural sector to reduce rural poverty and sustain the natural resource base. The pathways involve participation by rural communities, science and technology, knowledge generation and further learning, capacity enhancement, and institution building. Sustainable land management (SLM) an essential component of such policies will help to ensure the productivity of agriculture, forestry, fisheries, and hydrology. SLM will also support a range of ecosystem services on which agriculture depends. The 'Sustainable Land Management Sourcebook' provides a knowledge repository of tested practices and innovative resource management approaches that are currently being tested. The diverse menu of options represents the current state of the art of good land management practices. Section one identifies the need and scope for SLM and food production in relation to cross-sector issues such as freshwater and forest resources, regional climate and air quality, and interactions with biodiversity conservation and increasingly valuable ecosystem services. Section two categorizes the diversity of land management systems globally and the strategies for improving household livelihoods in each system type. Section three presents a range of investment notes that summarize good practice, as well as innovative activity profiles that highlight design of successful or innovative investments. Section four identifies easy-to-access, Web-based resources relevant for land and natural resource managers. The 'Sourcebook' is a living document that will be periodically updated and expanded as new material and findings become available on good land management practices. This book will be of interest to project managers and practitioners working to enhance land and natural resource management in developing countries.

Download or read book Fishery Science written by Lee A. Fuiman and published by John Wiley & Sons. This book was released on 2009-02-12 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now clear that data based on the studies of fish eggs and larvae make a number of unique contributions to fishery science that are crucial for accurate assessment and management of fish populations, including those of commercially important fisheries. This valuable book demonstrates why fish eggs and larvae are important, how the characteristics of early life stages require a somewhat different research approach and how information on early life stages can be applied and interpreted to yield unique insights into fish populations. The editors of Fishery Science have drawn together an extremely useful and well-written book with contributions from internationally respected researchers from North America, Asia and Europe. Chapters include a discussion of the unique nature of early life stages, age and growth, mortality, recruitment, populations analysis, habitats, human impacts and management. A carefully selected set of case studies demonstrates several specific applications of early life history information to a number of fishery problems. Fishery Science was designed to complement existing textbooks and is an essential purchase for all fisheries students and professionals, and for biologists working on the early life stages of fish. This exciting book is also of great value to ecologists, marine, freshwater and environmental scientists, populations biologists and oceanographers. All libraries in universities and research establishments where biological and fishery science are studied and taught should have copies of this book available on their shelves.

Book excerpt: Fishing has played a vital role in human history and culture. But today this key resource faces a serious crisis as most species are being overfished or fished to their very limit. Governments have tried to tackle the problem with limited success. Many of their actions have been counterproductive or ineffective. What will happen to global fisheries, and the populations that depend on them, as we continue to catch more fish than the oceans can reproduce? This book explores the causes of the current crisis in the world's fisheries, and what needs to be done to address the situation. It explains the structure of the fishing industry, the incentives that persuade individuals or companies to catch fish at unsustainable levels, and illuminates the problems created by governmental efforts to use fishing policy as a tool for economic development or to win votes in domestic elections. It also looks at the role of aquaculture in either decreasing or increasing the pressure on wild fish stocks. The dire condition of fish stocks has led governments and consumer organizations to consider new approaches to protect the global supply of fish. DeSombre and Barkin conclude by showing how such methods, along with new forms of international regulation and informed decision-making by consumers, all have an important part to play in rewarding and thus encouraging sustainable fishing behaviour in the future.
