Abstract As part of a national ecosystem review of large ocean management areas, this report examines the marine ecosystem of the Pacific North Coast Integrated Management Area (PNCIMA). PNCIMA encompasses approximately 102,000 km2 from the edge of the continental shelf east to the British Columbia mainland. The region extends from the British Columbia-Alaska border south […]
Summary This report provides a summary of the emerging consensus on indicators of marine ecosystems, and makes recommendations applicable to North Pacific waters of PICES interest. In addition, it attempts to take a broader view of indicators for EBM of marine systems rather than the narrower application to fisheries management (even though most research to […]
Abstract This report is the twelfth in an annual series on the state of physical, biological, and selected fishery resources of Canadian Pacific marine ecosystems. The region supports important resident and migratory populations of invertebrates, groundfish and pelagic fishes, marine mammals and seabirds. Monitoring the physical and biological oceanographic conditions and fishery resources of the […]
Abstract A new system of salmon status categorization will provide useful indicators of ocean conditions and climate variability in the North Pacific Ocean. Under Canada’s new Wild Salmon Policy, biological status will be assessed and categorized for a few hundred largely independent lineages of chinook, sockeye, coho, chum, and pink salmon. Changes to the status […]
Abstract This eleventh report of an annual series updates the state of physical, biological, and selected fishery resources of Canadian Pacific marine ecosystems. One of the biggest stories for 2009 was the return of far fewer Sockeye salmon than expected. Accurately forecasting salmon returns is difficult as there are few observations of salmon between the […]
Abstract This paper discusses how ecosystem modelling could be a valuable tool in the management and conservation of Canada’s west coast fisheries and salmon stocks. In this study ecosystem modelling refers to a computer application that examines aquatic ecosystems, and species therein, with the ability to simulate biological changes, such as biomass, mortality, catch, feeding […]
Abstract This report summarizes highlights from the tenth in an annual report series updating the state of physical, biological, and selected fishery resources of Canadian Pacific marine ecosystems. Canadian Pacific marine waters lie in a transition zone between coastal upwelling (California Current) and downwelling (Alaskan Coastal Current) regions, and experience strong seasonality and considerable freshwater […]
Executive Summary Fisheries ecosystem modelling could be a useful tool to complement present approaches to salmon research and management on Canada’s west coast. Ecosystem modelling refers to a computer application that simulates, through time, biological changes such as biomass, mortality, catch, feeding and competition in managed species. The models emulate such changes by considering factors […]
Summary This report is the thirteenth in an annual series on the state of physical, biological, and selected fishery resources of Canadian Pacific marine ecosystems. The region supports important resident and migratory populations of invertebrates, groundfish and pelagic fishes, marine mammals and seabirds. Monitoring the physical and biological oceanographic conditions and fishery resources of the […]
Abstract This report is the twelfth in an annual series on the state of physical, biological, and selected fishery resources of Canadian Pacific marine ecosystems. The region supports important resident and migratory populations of invertebrates, groundfish and pelagic fishes, marine mammals and seabirds. Monitoring the physical and biological oceanographic conditions and fishery resources of the […]
Abstract This report is the ninth in an annual series describing the state of physical, biological, and selected fishery resources of Pacific Canadian marine ecosystems. This region has seen dramatic changes in atmospheric and oceanic conditions over these years, all of which affect resident and migratory marine populations in B.C., many of which are of […]
Summary This report summarizes the thirteenth annual workshop on the state of physical, biological, and selected fishery resources of Canadian Pacific marine ecosystems. The region supports important resident and migratory populations of invertebrates, groundfish and pelagic fishes,marine mammals and seabirds. Monitoring the physical and biological oceanographic conditions and fishery resources of the Pacific Region is […]
