Computer Modelling of Marine Ecosystems

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 like environment, predation, competition or fisheries effects. Because these models capture both ecosystem and species changes over time, they offer a potential guide to future changes.
