The reports in this Bulletin summarize the studies of the early marine period of the life history of juvenile Pacific salmon. Review paper included: 1) A history of the research on the early marine life of Pacific salmon off Canada's Pacific coast; 2) Japanese studies on the early ocean life of juvenile salmon; 3) Review of Russian marine investigations of juvenile Pacific salmon; 4) Research conducted by the United States on the early ocean life of Pacific salmon.
Recent declines in the abundance of salmon in the Arctic-Yukon-Kuskokwim (AYK) region of western Alaska have created hardships for the people and communities who depend on this resource. In 2002, the AYK Sustainable Salmon Initiative (SSI) was created to undertake research to understand the reasons for this decline and to help support sustainable management in the region. This report makes recommendations for developing the research that the AYK SSI science plan should be based on, and relates the development of a restoration plan to the results of that research.
This book describes the work of the North Pacific Marine Science Organization (PICES) since its launch 1992. Mapping the evolution of its agenda gives insight into the development of modern marine science in the context of competing demands of stakeholders within and outside the organization. The opening chapter consider the challenges of marine science as a large scale, and places PICES in the contexts of internationalism and science-based resource management. They also lay out the organization’s longstanding focus on the development of climate science and its applications. Subsequent chapters explore the pros and cons of national vs. international science, negotiating the nature of investigation and cooperation across scientific, political and institutional boundaries in the region; national perspectives on purpose, scope, and mandates; assessing two major initiatives undertaken to date; the challenges of incorporating social science into an organization of mainly natural scientists.
This document provides a review, commentary and tabulations of the main trends that have occurred in exploitation of fisheries resources since the 1970s, largely as they are reflected in the FAO database on fishery landings, supplemented with selected information from the fishery literature. Reviews were prepared separately for the 15 main areas into which FAO divides the world's oceans for statistical purposes. They are then compared from a global perspective to reveal relative trends by species and areas, which are highlighted. Several special topics are reviewed, including tuna and tuna-like species, whales and dolphins, and environmental issues in fisheries.
This comprehensive text is a major synthesis on ecological change in the Gulf of Alaska. It encompasses the structural and annual changes, forces of change, long-ecological changes in the atmosphere and ocean, plankton, fish, birds and mammals, and the effects of the 1989 Exxon Valdez Oil Spill. With 5 major sections, Long-term Ecological Change in the Northern Gulf of Alaska first describes the physical features, the atmosphere and physical oceanography, the annual production cycle, the forage base for higher animals and trophic transfer, and the adaptations for survival in this changing environment for 9 portal species. Then, the major forces of change are introduced: climate, geophysics, fisheries and harvesting, species interactions, disease and contaminants. Next, the long-term records of change in physical factors and biological populations are presented, as well as the potential reasons for the biological changes. Following is the history of the Exxon Valdez oil spill and its long-term effects. And, finally, the emergent properties of the ecosystem are discussed and an attempt is made to weigh the importance of the major forcing factors in terms of their temporal and spatial scales of influence.* Examines important data on long-term change in the ecosystem and the forcing factors that are responsible for it * Provides an account of the 1989 Exxon Valdez oil spill with emphasis on the long-term effects * Describes the effects of climate change, geophysical change, species interactions, harvesting, disease, the 1989 oil spill, and marine contaminants on key populations of marine organisms
This publication describes major developments affecting fisheries in OECD countries, including changes in government policies, trade, and fisheries and aquaculture production. This edition contains a special chapter on fishing capacity and a special study on the Russian Federation.
