Public Summary — Computer Modelling of Marine Ecosystems: Applications to Pacific Salmon Management and Research

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 […]

Computer Modelling of Marine Ecosystems: Applications to Pacific Salmon Management and Research

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 […]

Economic Dimensions of Skeena Watershed Salmonid Fisheries

This report provides an economic snapshot of contemporary fisheries for Skeena salmon and steelhead, including aboriginal, commercial, and sport fisheries. The focus of the economic study is to: (1) gain a comprehensive understanding of the Skeena-area commercial salmon industry, (2) gain a similar level of understanding of the marine and freshwater recreational fisheries on the […]
