The Transition in the Contribution of Living Aquatic Resources to Food Security
The fishing industrys aggressive and expanding search for fish from the sea reached a turning point in 1990. After many years of increasing production, the global marine and inland catch from natural stocks declined from the 1989 peak of about 89 million tons to 85 million tons in 1993. Aquaculture production did not increase enough to meet the shortfall, and total production also fell in 1990 and 199. Present indications are that production from natural stocks will be below the current level in the year 2020; at best, it will maintain its present level. The author addresses five major issues: (1) maximizing the use of aquatic resources; (2) resource management; (3) intensification of fisheries exploitation; (4) integration of fisheries and aquaculture; and (5) the difficult problem of balancing national versus international interests.
Using Detection Dogs to Monitor Aquatic Ecosystem Health and Protect Aquatic Resources
This book is about the varied range of emerging applications using specially trained detection dogs to monitor and protect aquatic ecosystems, animals, plants and related resources. Featuring contributions from those at the forefront of converging disciplines ranging from canine training, ecological and biological monitoring, water resource management, law enforcement, and eco-toxicology, it addresses everyone already immersed in these or related fields, and anyone seeking to gain a broader understanding of them. Chapters cover several common themes including monitoring presence/absence through biological and ecological surveys; maintaining and evaluating water quality; law enforcement and a...

Efficient fishing methods and the highest advancements with the advent of mechanisation of fishing crafts in modern times, leading to dr...
Restoration of Aquatic Ecosystems
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
