Sea otters are good indicators of ocean health. In addition, they are a keystone species, offering a stabilizing effect on ecosystem, controlling sea urchin populations that would otherwise inflict damage to kelp forest ecosystems. The kelp forest ecosystem is crucial for marine organisms and contains coastal erosion. With the concerns about the imperiled status of sea otter populations in California, Aleutian Archipelago and coastal areas of Russia and Japan, the last several years have shown growth of interest culturally and politically in the status and preservation of sea otter populations. Sea Otter Conservation brings together the vast knowledge of well-respected leaders in the field, offering insight into the more than 100 years of conservation and research that have resulted in recovery from near extinction. This publication assesses the issues influencing prospects for continued conservation and recovery of the sea otter populations and provides insight into how to handle future global changes. - Covers scientific, cultural, economic and political components of sea otter conservation - Provides guidance on how to manage threats to the sea otter populations in the face of future global changes - Highlights the effects that interactions of coastal animals have with the marine ecosystem

The impetus for this volume comes from two sources. The first is scientific: by virtue of a preference for certain large benthic invertebrates as food, sea otters have interesting and significant effects on the structure and dynamics of nearshore communities in the North Pacific. The second is political: be cause of the precarious status of the sea otter population in coastal California, the U.S. Fish and Wildlife Service (USFWS) announced, in June 1984, a proposal to establish a new population of sea otters at San Nicolas Island, off southern California. The proposal is based on the premise that risks of catastrophic losses of sea otters, due to large oil spills, are greatly reduced by distributing the population among two geographically separate locations. The federal laws of the U.S. require that USFWS publish an Environmental Impact Statement (ElS) regarding the proposed translocation of sea otters to San Nicolas Island. The EIS is intended to be an assessment of likely bio logical, social, and economic effects of the proposal. In final form, the EIS has an important role in the decision of federal management authority (in this case, the Secretary of the Interior of the U.S.) to accept or reject the proposal.

This 592-page spiral-bound reference provides a baseline of information for all those involved with managing living marine resources in California and chronicles changes that have occurred in many of the state’s fisheries. Organized by marine ecosystems: bays and estuaries, nearshore and offshore. Includes illustrated species descriptions with details of biological knowledge, fishery history, landings data, population status and references. Also includes sections on marine birds and mammals and appendices containing management considerations (by species), a glossary of technical terms and acronyms and fishing gear illustrations. Jointly produced by the California Sea Grant Extension Program and the California Department of Fish and Game following the passage of the Marine Life Protection Act in January 1999.

"Captivating. . . . a full portrait of this adorable and ecologically important animal." —Publishers Weekly A science journalist travels the Pacific Coast in search of sea otters in this entertaining and inspiring book on the importance and history of this charismatic endangered species Sea otters—the adorable, furry marine mammals often seen floating on their backs holding hands—reveal the health of the coastal ecosystem along the Pacific Ocean. Once hunted for their prized fur in the 18th and 19th centuries, these animals nearly went extinct. Only now, nearly a century after hunting ceased, are populations showing stable growth in some places. Sea otters are a keystone species in coastal areas, feeding on sea urchins, clams, crab, and other crustaceans. When they are present, kelp beds are thick and healthy, providing homes for an array of sea life. When otters disappear, sea urchins take over, and the kelp disappears along with all the creatures that live in the beds. Now, thanks to their protected status, sea otters are making a comeback in California, Washington, and Alaska. In this hopeful book, science writer Todd McLeish embarks on an epic journey along the Pacific Coast—traveling from California to Alaska—to track the status, health, habits, personality, and viability of sea otters, and reveals how conservationists brought them back from the brink of extinction.
