Download or read book Ecosystem Concepts for Sustainable Bivalve Mariculture written by National Research Council and published by National Academies Press. This book was released on 2010-03-18 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. mariculture production of bivalve molluscs-those cultivated in the marine environment-has roughly doubled over the last 25 years. Although mariculture operations may expand the production of seafood without additional exploitation of wild populations, they still depend upon and affect natural ecosystems and ecosystem services. Every additional animal has an incremental effect arising from food extraction and waste excretion. Increasing domestic seafood production in the United States in an environmentally and socially responsible way will likely require the use of policy tools, such as best management practices (BMPs) and performance standards. BMPs represent one approach to protecting against undesirable consequences of mariculture. An alternative approach to voluntary or mandatory BMPs is the establishment of performance standards for mariculture. Variability in environmental conditions makes it difficult to develop BMPs that are sufficiently flexible and adaptable to protect ecosystem integrity across a broad range of locations and conditions. An alternative that measures performance in sustaining key indicators of ecosystem state and function may be more effective. Because BMPs address mariculture methods rather than monitoring actual ecosystem responses, they do not guarantee that detrimental ecosystem impacts will be controlled or that unacceptable impact will be avoided. Ecosystem Concepts for Sustainable Bivalve Mariculture finds that while performance standards can be applied for some broad ecosystem indicators, BMPs may be more appropriate for addressing parameters that change from site to site, such as the species being cultured, different culture methods, and various environmental conditions. This book takes an in-depth look at the environmental, social, and economic issues to present recommendations for sustainable bivalve mariculture.

Download or read book Homewaters written by David B. Williams and published by University of Washington Press. This book was released on 2021-04-24 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Not far from Seattle skyscrapers live 150-year-old clams, more than 250 species of fish, and underwater kelp forests as complex as any terrestrial ecosystem. For millennia, vibrant Coast Salish communities have lived beside these waters dense with nutrient-rich foods, with cultures intertwined through exchanges across the waterways. Transformed by settlement and resource extraction, Puget Sound and its future health now depend on a better understanding of the region’s ecological complexities. Focusing on the area south of Port Townsend and between the Cascade and Olympic mountains, Williams uncovers human and natural histories in, on, and around the Sound. In conversations with archaeologists, biologists, and tribal authorities, Williams traces how generations of humans have interacted with such species as geoducks, salmon, orcas, rockfish, and herring. He sheds light on how warfare shaped development and how people have moved across this maritime highway, in canoes, the mosquito fleet, and today’s ferry system. The book also takes an unflinching look at how the Sound’s ecosystems have suffered from human behavior, including pollution, habitat destruction, and the effects of climate change. Witty, graceful, and deeply informed, Homewaters weaves history and science into a fascinating and hopeful narrative, one that will introduce newcomers to the astonishing life that inhabits the Sound and offers longtime residents new insight into and appreciation of the waters they call home.

Download or read book Organism and Environment written by Sonia E. Sultan and published by OUP Oxford. This book was released on 2015-09-10 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, advances in both molecular developmental biology and evolutionary ecology have made possible a new understanding of organisms as dynamic systems interacting with their environments. This innovative book synthesizes a wealth of recent research findings to examine how environments influence phenotypic expression in individual organisms (ecological development or 'eco-devo'), and how organisms in turn alter their environments (niche construction). A key argument explored throughout the book is that ecological interactions as well as natural selection are shaped by these dual organism-environment effects. This synthesis is particularly timely as biologists seek a unified contemporary framework in which to investigate the developmental outcomes, ecological success, and evolutionary prospects of organisms in rapidly changing environments. Organism and Environment is an advanced text suitable for graduate level students taking seminar courses in ecology, evolution, and developmental biology, as well as academics and researchers in these fields.

Download or read book Shellfish Mariculture in Drakes Estero Point Reyes National Seashore California written by National Research Council and published by National Academies Press. This book was released on 2009-08-17 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Drakes Estero, which lies within the Point Reyes National Seashore (PRNS) about 25 miles northwest of San Francisco, California, was designated by Congress in 1976 as Potential Wilderness, it contained a commercial shellfish mariculture operation. Oyster mariculture began in Drakes Estero with the introduction of the nonnative Pacific oyster in 1932, and has been conducted continuously from that date forward. Hence, the cultural history of oyster farming predates the designation of Point Reyes as a National Seashore in 1962. Nevertheless, with the approach of the 2012 expiration date of the current National Park Service (NPS) Reservation of Use and Occupancy (RUO) and Special Use Permit (SUP) that allows Drakes Bay Oyster Company (DBOC) to operate within the estero, NPS has expressed concern over the scope and intensity of impacts of the shellfish culture operations on the estero's ecosystem. Public debate over whether scientific information justifies closing the oyster farm led to the request for this study to help clarify the scientific issues raised with regard to the shellfish mariculture activities in Drakes Estero.

Download or read book Coastal Heritage and Cultural Resilience written by Lisa L. Price and published by Springer. This book was released on 2018-11-24 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the knowledge, work and life of Pacific coastal populations from the Pacific Northwest to Panama. Center stage in this volume is the knowledge people acquire on coastal and marine ecosystems. Material and aesthetic benefits from interacting with the environment contribute to the ongoing building of coastal cultures. The contributors are particularly interested in how local knowledge -either recently generated or transmitted along generations- interfaces with science, conservation, policy and artistic expression. Their observations exhibit a wide array of outcomes ranging from resource and human exploitation to the magnification of cultural resilience and coastal heritage. The interdisciplinary nature of ethnobiology allows the chapter authors to have a broad range of freedom when examining their subject matter. They build a multifaceted understanding of coastal heritage through the different lenses offered by the humanities, social sciences, oceanography, fisheries and conservation science and, not surprisingly, the arts. Coastal Heritage and Cultural Resilience establishes an intimate bond between coastal communities and the audience in a time when resilience of coastal life needs to be celebrated and fortified.

Download or read book An Identification Guide to the Larval Marine Invertebrates of the Pacific Northwest written by Alan L. Shanks and published by . This book was released on 2001 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of larval invertebrates is a vital and growing field in contemporary marine science. The key ecological role of larvae in determining adult population sizes has been recognized for decades and has inspired extensive research. This volume, the first of its kind, is an identification guide to the planktonic larvae of shallow subtidal and intertidal invertebrates common to the Pacific Northwest coast.Each chapter provides a brief background to the larval biology of an invertebrate group; keys, drawings, and descriptions for the identification of larvae; a list of the species present in the Pacific Northwest; and a reference section. The geographic range covered is roughly from southeast Alaska to northern California; however many of the species are found along the entire coast of California, as far south as Baja California.An essential reference for anyone attempting to identify larval invertebrates from zooplankton samples, this working manual is intended for students as well as scientists and researchers. It offers an important new resource for marine biologists, biological oceanographers, marine and intertidal ecologists, and especially larval biologists.

Download or read book Nonnative Oysters in the Chesapeake Bay written by National Research Council and published by National Academies Press. This book was released on 2004-02-09 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonnative Oysters in the Chesapeake Bay discusses the proposed plan to offset the dramatic decline in the bay's native oysters by introducing disease-resistant reproductive Suminoe oysters from Asia. It suggests this move should be delayed until more is known about the environmental risks, even though carefully regulated cultivation of sterile Asian oysters in contained areas could help the local industry and researchers. It is also noted that even though these oysters eat the excess algae caused by pollution, it could take decades before there are enough of them to improve water quality.
