The Biosciences Division (Code 51) of the Naval Command, Control and Ocean Surveillance Center, RDT & E Division (NRaD) investigated and evaluated reintroduction to the wild as an option for managing the Navy's marine mammals. Data were gathered from expert sources and two NRaD-organized workshops. The first workshop involved experts in reintroduction and marine mammal research and management. It focused on identifying requirements for the reintroduction of captive marine mammals to the wild in general. Closing statements made by the participants are provided in appendices. The second workshop involved NRaD marine mammal experts and focused on applying the first workshop's general findings to an evaluation of the potential for reintroducing Navy marine mammals specifically. This report summarizes the workshops' findings, suggests a general model for planning a reintroduction program, and considers issues relevant to the Navy's marine mammal programs. This report recommends that the development of the required reintroduction methods and technologies could benefit the conservation of endangered species, but that the continued provision of lifetime care and maintenance for the Navy's marine mammals is the preferable option in terms of cost effectiveness.

This important scientific volume comprehensively explores the biology and ecological status of manatees and dugongs in all of the geographic regions where they can be found today, from the Caribbean to Eastern Africa, from Arabia to the Amazon, and from Japan through the South Pacific to Australia. Many of these dwindling populations are situated in developing countries--locales that have previously received little attention in the scientific literature. In these areas, people occupying rivers or coastlines still capture sirenians for food and other uses (oil, bones for carving, leather). In addition, disruption, erosion, or complete loss of sirenian habitat occurs because of dredge and fill, coastal run-off, chemical pollution, and damage from boat propellers. Sirenian Conservation features contributions from an international group of scientists who are working to address the many challenges to manatee and dugong food supply, environment, reproduction, and survival. They share stories of programs that rescue, rehabilitate, release, and monitor these animals; offer reports on practical, replicable, and cost-effective management techniques; and summarize current research strategies.

Whaling has become one of the most controversial environmental issues. It is not that all whale species are at the brink of extinction, but that whales have become important symbols to both pro- and anti-whaling factions and can easily be appropriated as the common heritage of humankind. This book, the first of its kind, is therefore not about whales and whaling per se but about how people communicate about whales and whaling. It contributes to a better understanding and discussion of controversial environmental issues: Why and how are issues selected? How is knowledge on these issues produced and distributed by organizations and activists? And why do affluent countries like Japan and Norway still support whaling, which is of insignificant economic importance? Basing his analysis on fieldwork in Japan and Norway and at the International Whaling Commission, the author argues how an image of a “superwhale” has been constructed and how this image has replaced meat and oil as the important whale commodity. He concludes that the whaling issue provides an arena where NGOs and authorities on each side can unite, swapping political legitimacy and building personal relations that can be useful on issues where relations are less harmonious.
