Book Description
This report documents results from a workshop on the estimation of salmon escapement, defined to be the number of adult salmon that escape marine fisheries and return to freshwater to spawn. The introductory session discussed effective methods for estimating escapement and the variability associated with different estimation techniques. Separate sessions provided area overviews and case studies of escapement estimation in British Columbia and Washington state; a review of salmon escapement databases; presentations on the training of fisheries staff in escapement data collection; and papers on new and developing technologies for salmon escapement estimation, including video technology and hydroacoustics. The bibliography includes references to literature on capture-recapture, visual counts, electronic and video techniques, hydroacoustic and other methods, and geographically-specific studies on escapement.

Book Description
This publication gives an updated review of the quantity of discards in the world's marine fisheries, using information from a broad range of fisheries in all continents. A number of policy issues are discussed including a 'no discards' approach to fisheries management, the need for balance between bycatch reduction and bycatch utilisation initiatives, and concerns arising from incidental catches of marine mammals, birds and reptiles. The report also highlights the need for more robust methods of estimating discards, and the development of bycatch management plans.

Book Description
Praise for the Second Edition "All statistics students and teachers will find in this book a friendly and intelligentguide to . . . applied statistics in practice." —Journal of Applied Statistics ". . . a very engaging and valuable book for all who use statistics in any setting." —CHOICE ". . . a concise guide to the basics of statistics, replete with examples . . . a valuablereference for more advanced statisticians as well." —MAA Reviews Now in its Third Edition, the highly readable Common Errors in Statistics (and How to Avoid Them) continues to serve as a thorough and straightforward discussion of basic statistical methods, presentations, approaches, and modeling techniques. Further enriched with new examples and counterexamples from the latest research as well as added coverage of relevant topics, this new edition of the benchmark book addresses popular mistakes often made in data collection and provides an indispensable guide to accurate statistical analysis and reporting. The authors' emphasis on careful practice, combined with a focus on the development of solutions, reveals the true value of statistics when applied correctly in any area of research. The Third Edition has been considerably expanded and revised to include: A new chapter on data quality assessment A new chapter on correlated data An expanded chapter on data analysis covering categorical and ordinal data, continuous measurements, and time-to-event data, including sections on factorial and crossover designs Revamped exercises with a stronger emphasis on solutions An extended chapter on report preparation New sections on factor analysis as well as Poisson and negative binomial regression Providing valuable, up-to-date information in the same user-friendly format as its predecessor, Common Errors in Statistics (and How to Avoid Them), Third Edition is an excellent book for students and professionals in industry, government, medicine, and the social sciences.

Book Description
"Rebuilding depleted stocks is a central part of the fisheries governance agenda. By analysing the available literature, Part 1 of "Rebuilding of marine fisheries" provides a global review of the emergence of the rebuilding paradigm, its key concepts, the trends in fishery resources, and the empirical evidence available on stocks depletion, collapse and rebuilding. It addresses the bio-ecological, economic, and human dimensions of rebuilding or restoration of stocks, multispecies assemblages and habitats/ecosystems and touches on the need for rebuilding at the whole sector level when depletion has become widespread and chronic. The human imensions of stocks and fisheries are given particular attention, looking at conflicting objectives, the bio-economy of rebuilding, its costs and benefits, and the distributional effects of the related reform among actors with their potential social consequences in the short and long terms. Governance is addressed in detail: legal and policy frameworks; rationale and objectives of a rebuilding regime; alternative rebuilding strategies; reference values and protocols; regulatory time-frames; risk management and harvest control rules; impacts of climatic oscillations; management tool-box; implementation guidance and performance evaluation. The document ends with a review of the determinants of success of a rebuilding programme."--Publisher's description for part 1.

Book Description
The California Current System is one of the best studied ocean regions of the world, and the level of oceanographic information available is perhaps only surpassed by the northeast and northwest Atlantic. The current literature (later than 1993) offers no comprehensive, integrated review of the regional fisheries oceanography of the California Current System. This volume summarizes information of more than 60-year California Cooperative Oceanic Fisheries Investigation (CalCOFI). While providing a large bibliography, the intent was to extract themes relevant to current research rather than to prepare a compendious review of the literature. The work presents a useful review and reference point for multidisciplinary fisheries scientists and biological oceanographers new to working in the California Current System, and to specialists wishing to access information outside their core areas of expertise. In addition it aims to deliver an up to date reference to the current state of knowledge of fisheries oceanography in the California Current System.

Book Description
This book develops an adaptive approach to environmental impact assessment and management and is based on a study initiated by a workshop convened in early 1974 by SCOPE (Scientific Committee on Problems of the Environment). CS Holling discusses the nature and behavior of ecological systems and its issues, limitations, and potential of environmental assessment. Further, he discusses how we can incorporate impact assessment studies with actual environmental planning and decision making.Crawford Holling received his B.A. and M.Sc. at the University of Toronto (1952) and his Ph.D. at the University of British Columbia (1957). He worked in the laboratories of the Department of the Environment, Government of Canada. Since then, he has been, at various times, Professor and Director of the Institute of Resource Ecology, University of British Columbia, Vancouver, Canada, and Director of the International Institute for Applied Systems Analysis (IIASA), Vienna, Austria. He now occupies the Arthur R. Marshall Jr. Chair in Ecological Sciences at the University of Florida and has launched a comparative study of the structure and dynamics of ecosystems.

Book Description
What causes bear attacks? When should you play dead and when should you fight an attacking bear? What do we know about black and grizzly bears and how can this knowledge be used to avoid bear attacks? And, more generally, what is the bear’s future? Bear Attacks is a thorough and unflinching landmark study of the attacks made on men and women by the great grizzly and the occasionally deadly black bear. This is a book for everyone who hikes, camps, or visits bear country–and for anyone who wants to know more about these sometimes fearsome but always fascinating wild creatures.
