Excerpt from Destruction of Undersized Haddock on Georges Bank, 1947-51 In normal fishing operations, the entire catch from a haul is dumped into one or more checkers (fig. From these checkers the marketable fish are selected and separated according to species. The haddock are graded for size, then gutted and tossed into a wash box from which they are pitched below decks for icing. The biologist usually obtains his measurements and scale samples of the marketable fish before the fish are gutted.

Leading political innovation activist Katherine Gehl and world-renowned business strategist Michael Porter bring fresh perspective, deep scholarship, and a real and actionable solution, Final Five Voting, to the grand challenge of our broken political and democratic system. Final Five Voting has already been adopted in Alaska and is being advanced in states across the country. The truth is, the American political system is working exactly how it is designed to work, and it isn't designed or optimized today to work for us—for ordinary citizens. Most people believe that our political system is a public institution with high-minded principles and impartial rules derived from the Constitution. In reality, it has become a private industry dominated by a textbook duopoly—the Democrats and the Republicans—and plagued and perverted by unhealthy competition between the players. Tragically, it has therefore become incapable of delivering solutions to America's key economic and social challenges. In fact, there's virtually no connection between our political leaders solving problems and getting reelected. In The Politics Industry, business leader and path-breaking political innovator Katherine Gehl and world-renowned business strategist Michael Porter take a radical new approach. They ingeniously apply the tools of business analysis—and Porter's distinctive Five Forces framework—to show how the political system functions just as every other competitive industry does, and how the duopoly has led to the devastating outcomes we see today. Using this competition lens, Gehl and Porter identify the most powerful lever for change—a strategy comprised of a clear set of choices in two key areas: how our elections work and how we make our laws. Their bracing assessment and practical recommendations cut through the endless debate about various proposed fixes, such as term limits and campaign finance reform. The result: true political innovation. The Politics Industry is an original and completely nonpartisan guide that will open your eyes to the true dynamics and profound challenges of the American political system and provide real solutions for reshaping the system for the benefit of all.

Computation and Interpretation of Biological Statistics of Fish Populations, first published in 1975, deals with the general field of biological statistics of fish populations. It is a compilation of the more important procedures used to estimate abundance, age composition, rate of growth, and mortality rates in fish populations, with working examples of all the computations. Computation and Interpretation of Biological Statistics of Fish Populations is one of the most highly cited scientific references in the field of fisheries.
It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.
Addressing a field that has been dominated by astronomers, physicists, engineers, and computer scientists, the contributors to this collection raise questions that may have been overlooked by physical scientists about the ease of establishing meaningful communication with an extraterrestrial intelligence. These scholars are grappling with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected. By drawing on issues at the core of contemporary archaeology and anthropology, we can be much better prepared for contact with an extraterrestrial civilization, should that day ever come.
This publication comprises the proceedings of an international workshop convened in St. John's, Nfld, Nov. 26-29, 1979. The purpose of the workshop was to discuss the results of recent multispecies research, its applications to management, and to consider future directions for research in this field. A total of 26 papers were presented, including a combination of experience papers, state-of-the-art review, and new scientific findings. Sequential sessions were held on fisheries systems research by the Department of Fisheries and Oceans, multispecies considerations in fisheries research and management advice in the ICES area, species interactions in the Northeast Pacific and Northwest Atlantic, fisheries interactions, and applications to fisheries management. The workshop concluded with a substantial discussion of implications of present knowledge for advice to fisheries managers and implications for research program planning. The Workshop Report comprises the Chairman's opening remarks, a report on main elements of discussion in the sessions, and a summarization of workshop conclusions.
The Worldwide review of bottom fisheries in the high seas in 2016 is an update to the first Worldwide review of bottom fisheries in the high seas, published in 2009 based on information from 2003 to 2006. It provides states and other interested parties with a summary of the current status of high seas bottom fisheries worldwide. The present, updated review begins with a description of the demersal finfish and shellfish resources, before offering a global perspective on fisheries and management; it then provides specific, regional information over eleven chapters covering the high seas of the world’s oceans, by region. Drawing on data up to and including 2016, it provides a survey of the current state of bottom fisheries since the original Worldwide review, considering these fisheries in the context of their historical evolution.
Shifting Baselines explores the real-world implications of a groundbreaking idea: we must understand the oceans of the past to protect the oceans of the future. In 1995, acclaimed marine biologist Daniel Pauly coined the term "shifting baselines" to describe a phenomenon of lowered expectations, in which each generation regards a progressively poorer natural world as normal. This seminal volume expands on Pauly's work, showing how skewed visions of the past have led to disastrous marine policies and why historical perspective is critical to revitalize fisheries and ecosystems. Edited by marine ecologists Jeremy Jackson and Enric Sala, and historian Karen Alexander, the book brings together knowledge from disparate disciplines to paint a more realistic picture of past fisheries. The authors use case studies on the cod fishery and the connection between sardine and anchovy populations, among others, to explain various methods for studying historic trends and the intricate relationships between species. Subsequent chapters offer recommendations about both specific research methods and effective management. This practical information is framed by inspiring essays by Carl Safina and Randy Olson on a personal experience of shifting baselines and the importance of human stories in describing this phenomenon to a broad public. While each contributor brings a different expertise to bear, all agree on the importance of historical perspective for effective fisheries management. Readers, from students to professionals, will benefit enormously from this informed hindsight.
Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.
