Download or read book Operational Plan Reproductive and Biological Sampling of Yelloweye Rockfish Sebastes Ruberrimus and Black Rockfish Sebastes Melanops from Southeast Alaska Sport and Commercial Fisheries written by Kelly S. Reppert and published by . This book was released on 2022 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a limited understanding of the reproductive biology of yelloweye rockfish (Sebastes ruberrimus) and black rockfish (S. melanops) in Alaskan waters. The purpose of this project is to sample yelloweye and black rockfish in order to estimate maturity schedules (length and age at maturity) and fecundity (both absolute and relative) in Southeast Alaska. An understanding of the reproductive biology of these rockfish species is necessary for science-based management and population dynamics modeling for stock assessment purposes. This project will estimate important life history parameters for these rockfish in Southeast Alaska.

Download or read book The Rockfishes of the Northeast Pacific written by Milton S. Love and published by Univ of California Press. This book was released on 2002 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A major landmark contribution to fisheries science and fish ecology. Rockfish populations are in a severe decline throughout the Northeastern Pacific, and the need for a deep understanding of their biology, ecology, and management has never been more critical. This book addresses all aspects of our current knowledge of this diverse and interesting group of groundfish species, and it is written clearly and with humor. An outstanding work!"--Larry G. Allen, California State University, Northridge "Quite simply the best account ever of the fascinating, diverse, and valuable rockfishes. If you are interested in the marine fishes of the Pacific Coast, you need this book."--Peter B. Moyle, author of Inland Fishes of California
Download or read book Stock Identification Methods written by Steven X. Cadrin and published by Academic Press. This book was released on 2013-10-04 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stock Identification Methods, 2e, continues to provide a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, this valuable resource offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach. - Describes 18 distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks - Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method - Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis - Focuses on the challenges of interpreting data and managing mixed-stock fisheries
Download or read book Climate Change and Human Responses written by Gregory Monks and published by Springer. This book was released on 2017-03-21 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contributes to the current discussion on climate change by presenting selected studies on the ways in which past human groups responded to climatic and environmental change. In particular, the chapters show how these responses are seen in the animal remains that people left behind in their occupation sites. Many of these bones represent food remains, so the environments in which these animals lived can be identified and human use of those environments can be understood. In the case of climatic change resulting in environmental change, these animal remains can indicate that a change has occurred, in climate, environment and human adaptation, and can also indicate the specific details of those changes.

Book excerpt: Drafting a Conservation Blueprint lays out for the first time in book form a step-by-step planning process for conserving the biological diversity of entire regions. In an engaging and accessible style, the author explains how to develop a regional conservation plan and offers experience-based guidance that brings together relevant information from the fields of ecology, conservation biology, planning, and policy. Individual chapters outline and discuss the main steps of the planning process, including: • an overview of the planning framework • selecting conservation targets and setting goals • assessing existing conservation areas and filling information gaps • assessing population viability and ecological integrity • selecting and designing a portfolio of conservation areas • assessing threats and setting priorities A concluding section offers advice on turning conservation plans into action, along with specific examples from around the world. The book brings together a wide range of information about conservation planning that is grounded in both a strong scientific foundation and in the realities of implementation.
Download or read book Waters in Peril written by Leah Bendell-Young and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Who Speaks for the Oceans? The question has been asked a lot in recent years - just who is looking out for our oceans? Covering over seventy percent of the earth's surface it is the world's largest common property resource,jojntly owned by over six billion humans. It is the foundation for life on earth as we know it. Over the years, many people have spoken about various aspects of our ocean environments and they have spoken to different audiences in many different ways. For many in the public realm, Jacques Cousteau spoke for the ocean. Since his passing, no single voice with the sallle public identity or recognition has emerged. Certainly the many governments bordering our oceans cannot agree on common principles or issues of ocean use and management. We might be tempted think that we do not have an ocean spokesperson or champion, but we would be wrong. Today, the rapidly growing number of scientists working hard to expand our under standing of our ocean realm are the ocean voices we should listen to. At the same time as our scientists advance their understanding of the oceans, we all need to advance our abilities and commitment to communicate on behalf of the oceans with broader and broader audiences who need to be aware of where things stand. Often called "the last great frontier", earth's oceans are vast, widely varied, and are hard to get to, arid into, to do the research we need done.

Available in PDF, EPUB and Kindle. Book excerpt: The last half-century has shown a dramatic increase in the standard of living of millions of people in Europe, North America and many parts of the Third World. This has, in many ways been brought about by scientific and technical developments which were initiated in the 1940s and 1950s. Promises were then made that nuclear energy would provide electricity so cheap that it would not need metering, pesticides would end malnutrition throughout the world and plastics and other synthetic chemicals would revolutionise our manufacturing industry and our way of life. Whilst some of these promises have been fulfilled, the problems of long-term health risks to humans and wildlife arising from the use, production and disposal of these products were either unknown or deliberately understated. Nuclear power is rendered economically unviable when the real cost of decommissioning and storage of waste for several millenia is included, and the effects on health of both humans and wildlife of early pest eradication programmes with organochlorine pesticides were well documented in Rachel Carson's "Silent Spring". Evidence of the effects of aerosols and refrigerants on depletion of the ozone layer has led to restriction on the use of CFCs, and there is now increasing evidence of climate change resulting from our profligate use of fossil fuels.
