Book Description
"Preliminary report in which sockeye escapement goals are given for each of the major systems in Bristol Bay for 1966... Although this preliminary forecast of 23.9 million sockeye originally represented the total return (including those fish to be harvested by the Japanese high seas fishery) to Bristol Bay, more recent analysis ... indicates that the final forecast will be substatially larger"--Leaf [2] of cover.

Book Description
The last major synthesis of our knowledge of fish migration and the underlying transport and guidance phenomena, both physical and biological, was "Fish Migration" published 16 years ago by F.R. Harden Jones (1968). That synthesis was based largely upon what could be gleaned by classical fishery-biology techni.ques, such as tagging and recapture studies, commercial fishing statistics, and netting and trapping studies. Despite the fact that Harden Jones also provided, with a good deal of thought and speculation, a theoretical basis for studying the various aspects of fish migration and migratory orientation, progress in this field has been, with a few excepti.ons, piecemeal and more disjointed than might have been expected. Thus we welcomed the approach from the NATO Marine Sciences Programme Panel and the encouragement from F.R. Harden Jones to develop a proprosal for, and ultimately to organize, a NATO Advanced Research Institute (ARI) on mechanisms of fish migration. Substantial progress had been made with descriptive, analytical and predictive approaches to fish migration since the appearance of "Fish ~ligration." Both because of the progress and the often conflicting results of research, we felt that the time was again right and the effort justified to synthesize and to critically assess our knowledge. Our ultimate aim was to identify the gains and shortcomings and to develop testable hypotheses for the next decade or two.

Book Description
The Atlantic salmon (Salmo salar) has occupied a salient position in the history of eastern North America for at least the past 1000 years. Initially the species occupied a prominant niche in the prolific web of life that existed throughout its former occurrence area; millions of pounds of salmon were produced annually from the freshwater streams between New York and Ungava - a resource that was a principal food source for the Amerindian cultures which shared its range. In a chronological and cumulative way, the salmon became an increasingly important factor in both the domestic and commercial life of the developing colonies; it provided a recreational outlet for the sportsman, and evolved as a principal object of intellectual and scientific investigation. The documented specifics of the salmon's history, however, are largely comprised of repetitive instances of overexploitation, careless destruction of stocks and their environment, and ineffectual conservation actions. Despite the species' former importance, its more recent history is one of declining presence, and its destiny appears to be extinction. By documenting this story of discovery, exploitation, and decline, the urgent need for the employment of sound resource management practices to preserve the salmon is emphasized. Appendix A: Historical methods of packing salmon.

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.
