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.

Available in PDF, EPUB and Kindle. Book excerpt: This environmental history of America’s largest estuary provides insight into how and why its former productivity and abundant fisheries have declined. The concept of “shifting baselines”—changes in historical reference points used in environmental assessments—illuminates a foundational challenge when evaluating the health of ecosystems and seeking to restore degraded wildlife populations. In this important book, Victor S. Kennedy examines the problem of shifting baselines for one of the most productive aquatic resources in the world: the Chesapeake Bay. Kennedy explains that since the 1800s, when the Bay area was celebrated for its aquatic bounty, harvest baselines have shifted downward precipitously. Over the centuries, fishers and hunters, supported by an extensive infrastructure of boats, gear, and processing facilities, overexploited the region’s fish, crustaceans, terrapin, and waterfowl, squandering a profound resource. Beginning with the colonial period and continuing through the twentieth century, Kennedy gathers an unparalleled collection of scientific resources and eyewitness reports by colonists, fishers, managers, scientists, and newspaper reporters to create a comprehensive examination of the Chesapeake’s environmental history. Focusing on the relative productivity and health of its fisheries and wildlife and highlighting key species such as shad, oysters, and blue crab, Shifting Baselines in the Chesapeake Bay helps readers understand the remarkable extent of the Bay’s natural resources in the past so that we can begin to understand what has changed since, and why. Such knowledge can help illustrate the Bay’s potential fertility and stimulate efforts to restore this pivotal maritime system’s ecological health and productivity.

Download or read book The Oyster Question written by Christine Keiner and published by University of Georgia Press. This book was released on 2010 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Oyster Question, Christine Keiner applies perspectives of environmental, agricultural, political, and social history to examine the decline of Maryland’s iconic Chesapeake Bay oyster industry. Oystermen have held on to traditional ways of life, and some continue to use preindustrial methods, tonging oysters by hand from small boats. Others use more intensive tools, and thus it is commonly believed that a lack of regulation enabled oystermen to exploit the bay to the point of ruin. But Keiner offers an opposing view in which state officials, scientists, and oystermen created a regulated commons that sustained tidewater communities for decades. Not until the 1980s did a confluence of natural and unnatural disasters weaken the bay’s resilience enough to endanger the oyster resource. Keiner examines conflicts that pitted scientists in favor of privatization against watermen who used their power in the statehouse to stave off the forces of rural change. Her study breaks new ground regarding the evolution of environmental politics at the state rather than the federal level. The Oyster Question concludes with the impassioned ongoing debate over introducing nonnative oysters to the Chesapeake Bay and how that proposal might affect the struggling watermen and their identity as the last hunter-gatherers of the industrialized world.

Download or read book The Aquatic Frontier written by Samuel P. Hanes and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although few remember their former significance, oysters were one of the largest U.S. fisheries at their peak in the late nineteenth century. As the fishery industrialized on-and offshore, oyster farms and canning factories spread along the Eastern Seaboard, with overharvesting becoming increasingly common. During the Progressive Era, state governments founded new agencies to cope with this problem and control this expanding economy. Regulators faced a choice: keep elaborate conservation systems based on common property rights or develop new ones with private, hatchery-stocked aquaculture farms. The tradition-preserving solution won, laying the groundwork for modern oyster management. The Aquatic Frontier explores the forms this debate took between 1870 and 1920 in law enforcement, legislative advising, natural science, and oyster cartography. Samuel P. Hanes argues that the effort to centralize and privatize the industry failed due to a lack of understanding of the complex social-ecological systems in place--a common dilemma for environmental managers in this time period and for fisheries management confronting dangers from dwindling populations today.
