Evolving Approaches to Managing Marine Recreational Fisheries
"Increasing coastal populations, rising recreational demand, and growing conflicts with other users are adding to the challenge of managing marine recreational fisheries today. Traditional regulations - such as daily bag limits and seasonal closures - are often not enough to control fishing impacts and they tend to generate greater discontent and lower economic benefits in the angling community as they become more restrictive. This volume is the first to examine management approaches that promise to better control fishing, generate more information on fishing impacts, and give anglers more freedom to enjoy their sport."--BOOK JACKET.
Exploration of the Seas
In the summer of 1803, Thomas Jefferson sent Meriwether Lewis and William Clark on a journey to establish an American presence in a land of unqualified natural resources and riches. Is it fitting that, on the 200th anniversary of that expedition, the United States, together with international partners, should embark on another journey of exploration in a vastly more extensive region of remarkable potential for discovery. Although the oceans cover more than 70 percent of our planet's surface, much of the ocean has been investigated in only a cursory sense, and many areas have not been investigated at all. Exploration of the Seas assesses the feasibility and potential value of implementing a m...
International Bibliography of Economics
IBSS is the essential tool for librarians, university departments, research institutions and any public or private institution whose work requires access to up-to-date and comprehensive knowledge of the social sciences.
Review Procedures for Water Resources Project Planning
The U.S. Army Corps of Engineers, through its civil works program, can take pride in its contributions throughout our nation's history to the development of waterways infrastructure, navigation, flood damage reduction, water resources development and protection, and environmental restoration. Many projects that have been pioneering in their concept and bold in their execution were made possible by the creativity and dedication of outstanding scientists, engineers, and builders. The Corps has always had review processes for evaluation of its planning studies and projects, with the focus often being largely on the technical aspects. In recent years, however, increased consideration of such fac...
Nonnative Oysters in the Chesapeake Bay
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.
Spills of Emulsified Fuels
Spills of Emulsified Fuels: Risks and Response is part of an evolving body of work conducted by the National Research Council (NRC) to help inform debate and decision-making regarding the ecological consequences of releases associated with the widespread use of fossil fuels. Like earlier NRC reports, it attempts to understand the chemical, physical, and biological behavior of a complex mix of compounds that make up various petroleum hydrocarbon-based fuels. The specific risk factors presented by emulsified fuels are difficult to characterize, mainly because there have been no spills of emulsified fuels to date, and thus there is little practical experience with these products.
Future Needs in Deep Submergence Science
Deep-diving manned submersibles, such as Alvin, which gained worldwide fame when researchers used it to reach the wreck of the Titanic, have helped advance deep-ocean science. But many scholars in this field have noted that the number and capabilities of today's underwater vehicles no longer meet current scientific demands. At the same time, the relative value of manned and unmanned vehicles is often disputed. The report finds that new submersibles-both manned and unmanned-that are more capable than those in the current fleet are needed and would be of great value to the advancement of ocean research.
Effects of Trawling and Dredging on Seafloor Habitat
Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.
Pesticide Law and Compliance Decision Making
This book investigates pesticide compliance in China in order to provide a more comprehensive understanding of compliance and offers some feasible and adaptable suggestions for enhancing the effectiveness of this compliance. It discusses the weak implementation of Chinese laws and rules and emphasizes the necessity and importance of a compliance perspective in China that focuses on why laws are obeyed or broken. It examines how vegetable farmers’ perceptions of amoral calculation affect their pesticide compliance behavior and analyzes how the legitimacy of law is related to compliance to better explain how all the variables interact to shape compliance. It discusses both qualitative and quantitative methods, and uses a large-N qualitative approach, which allows for systematic analysis and in-depth exploration. This book will help readers to understand compliance in developing China by adopting and developing compliance theories which are broadly developed in the West.
